Cuarenta Casas is thought to be a branch of which settlement?


La Cueva De Las Ventanas (The Cave of Windows), a series of cliff dwellings along an important trade route, and Las Jarillas Cave scrambled along the canyons of the Sierra Madre in Northwestern Chihuahua date between AD 1205 and 1260 and belong to the Paquimé culture. Cuarenta Casas is thought to have been a branch settlement from Paquime to protect the trade route from attack. Archaeologists believe the civilization began to decline during the 13th century and by the 15th century the inhabitants of Paquime sought refuge in the Sierra Madre Occidental while others are thought to have emigrated north and joined the Ancestral Pueblo peoples. According to anthropologist current natives tribes (Yaqui, Mayo, Opata, and Tarahumara) are descendants of the Casas Grandes culture.


Which current native tribes are thought to be descendants of the Casas Grandes?


Which precious metal did Biezma discover?

and Camargo. In 1631 Juan Rangel de Biezma discovered a rich vein of silver, and subsequently established San Jose del Parral near the site. Parral remained an important economic and cultural center for the next 300 years. On December 8, 1659 Fray García de San Francisco founded the mission of Nuestra Señora de Guadalupe de Mansos del Paso del Río del Norte and founded the town El Paso Del Norte (present day Ciudad Juárez) in 1667. The Spanish society that developed in the region replaced the sparse population of indigenous peoples. The absence of servants and workers forged the spirit of northern people as self-dependent, creative people that defended their European heritage. In 1680 settlers from Santa Fe, New Mexico sought refuge in El Paso Del Norte for twelve years after fleeing the attacks from Pueblo tribes, but returned to Santa Fe in 1692 after Diego de Vargas recaptured the city and vicinity. In 1709, Antonio de Deza y Ulloa founded the state capital Chihuahua City; shortly after, the city became the headquarters for the regional mining offices of the Spanish crown known as Real de Minas de San Francisco de Cuéllar in honor of the Viceroy of New Spain, Francisco Fernández de la Cueva Enríquez, Duke of Alburquerque and the Marquee of Cuéllar..

How many people left the state for the U.S. between 2000-2005?

During the period from 2000–2005 it is estimated that 49,722 people left the state for the United States. Some 82,000 people are thought to have immigrated to the state from 2000–2005 mainly coming from Veracruz (17.6%), United States (16.2%), Durango (13.2%), Coahuila (8.0%) and Chiapas (4.5%). It is believed that there is a large number of undocumented immigrants in that state the come from Central and South America which mainly settle in Ciudad Juárez. According to the 2005 census, the population grew 1.06% from 2000 to 2005. The state has an uneven settlement of people and the lowest population density of any Mexican state; according to the 2005 census there were 12 people per km2. Of all the 3,241,444 people in the state, two-thirds (2,072,129) live in the cities of Ciudad Juárez and Chihuahua. Only three other cities have populations over 100,000: Parral 101,147, Cuauhtémoc 105,725, and Delicias 108,187.

Which nicknames were used to form the conservative and liberal elements?

In the constituent legislature or convention, the conservative and liberal elements formed using the nicknames of Chirrines and Cuchas. The military entered as a third party. The elections for the first regular legislature were disputed, and it was not until May 1, 1826, that the body was installed. The liberals gained control and the opposition responded by fomenting a conspiracy. This was promptly stopped with the aid of informers, and more strenuous measures were taken against the conservatives. Extra powers were conferred on the Durango governor, Santiago Baca Ortiz, deputy to the first national congress, and leader of the liberal party.


In 1562 Francisco de Ibarra headed a personal expedition in search of the mythical cities of Cibola and Quivira; he traveled through the present-day state of Chihuahua. Francisco de Ibarra is thought to have been the first European to see the ruins of Paquime. In 1564 Rodrigo de Río de Loza, a lieutenant under Francisco de Ibarra, stayed behind after the expedition and found gold at the foot of the mountains of the Sierra Madre Occidental; he founded the first Spanish city in the region, Santa Barbara in 1567 by bringing 400 European families to the settlement. A few years later in 1569 Franciscan missionaries led by Fray Agustín Rodríguez from the coast of Sinaloa and the state of Durango founded the first mission in the state in Valle de San Bartolomé (present-day Valle de Allende). Fray Agustín Rodríguez evangelized the native population until 1581. Between 1586 and 1588 a epidemic caused a temporary exodus of the small population in the territory of Nueva Vizcaya.

According to the Instituto Nacional de Estadística, Geografía e Informática (INEGI), 95.6% of the population over the age of 15 could read and write Spanish, and 97.3% of children of ages 8–14 could read and write Spanish. An estimated 93.5% of the population ages 6–14 attend an institution of education. Estimated 12.8% of residents of the state have obtained a college degree. Average schooling is 8.5 years, which means that in general the average citizen over 15 years of age has gone as far as a second year in secondary education.

The state's economy ranks in what place in the country Mexico

The state has the 12th-largest state economy in Mexico, accounting for 2.7% of the country’s GDP. Chihuahua has the fifth highest manufacturing GDP in Mexico and ranks second for the most factories funded by foreign investment in the country. As of 2011[update], the state had an estimated 396 billion pesos (31.1 billion dollars) of annual GDP. According to official federal statistical studies, the service sector accounted for the largest portion of the state economy at 59.28%; the manufacturing and industrial sector is estimated to account for 34.36% of the state's GDP, with the agricultural sector accounting for 6.36% of the state's GDP.

Who was the first person elected under the new constitution?

The general features of the preceding occurrence applied also to Chihuahua, although in a modified form. The first person elected under the new constitution of 1825 was Simón Elías Gonzalez, who being in Sonora, was induced to remain there. José Antonio Arcé took his place as ruler in Chihuahua. In 1829, González became general commander of Chihuahua, when his term of office on the west coast expired. Arcé was less of a yorkino than his confrere of Durango. Although unable to resist the popular demand for the expulsion of the Spaniards, he soon quarreled with the legislature, which declared itself firmly for Guerrero, and announcing his support of Bustamante's revolution, he suspended, in March 1830, eight members of that body, the vice-governor, and several other officials, and expelled them from the state. The course thus outlined was followed by Governor José Isidro Madero, who succeeded in 1830, associated with J. J. Calvo as general commander, stringent laws being issued against secret societies, which were supposed to be the main spring to the anti-clerical feeling among liberals.

In which region of the state did culture develop?

Between AD 300 and 1300 in the northern part of the state along the wide, fertile valley on the San Miguel River the Casas Grandes (Big Houses) culture developed into an advanced civilization. The Casas Grandes civilization is part of a major prehistoric archaeological culture known as Mogollon which is related to the Ancestral Pueblo culture. Paquime was the center of the Casas Grandes civilization. Extensive archaeological evidence shows commerce, agriculture, and hunting at Paquime and Cuarenta Casas (Forty Houses).

Until what year did the state remain calm?

The state seemed at relative calm compared to the rest of the country due to its close ties to the United States until 1841. In 1843 the possibility of war was anticipated by the state government and it began to reinforce the defense lines along the political boundary with Texas. Supplies of weapons were sent to fully equip the military and took steps to improve efficiency at the presidios. Later, the Regimen for the Defenders of the Border were organized by the state which were made up of: light cavalry, four squads of two brigades, and a small force of 14 men and 42 officials at the price of 160,603 pesos per year. During the beginning of the 1840s, private citizens took it upon themselves to stop the commercial caravans of supplies from the United States, but being so far away from the large suppliers in central Mexico the caravan was allowed to continue in March 1844. Continuing to anticipate a war, the state legislature on July 11, 1846 by decree enlisted 6,000 men to serve along the border; during that time Ángel Trías quickly rose to power by portraying zealous anti-American rhetoric. Trías took the opportunity to dedicate important state resources to gain economic concessions from the people and loans from many municipalities in preparation to defend the state; he used all the money he received to equip and organize a large volunteer militia. Ángel Trías took measures for state self-dependence in regards to state militia due to the diminishing financial support from the federal government.

Which city became the launching place for expeditions into New Mexico?

Santa Bárbara became the launching place for expeditions into New Mexico by Spanish conquistadors like: Antonio de Espejo, Gaspar Castaño, Antonio Gutiérrez de Umaña, Francisco Leyba de Bonilla, and Vicente de Zaldívar. Several expeditions were led to find a shorter route from Santa Barbara to New Mexico. In April 1598, Juan de Oñate finally found a short route from Santa Barbara to New Mexico which came to be called El Paso del Norte (The Northern Pass). The discovery of El Paso Del Norte was important for the expansion of El Camino Real de Tierra Adentro (The Inner Land Royal Road) to link Spanish settlements in New Mexico to Mexico City; El Camino Real de Tierra Adentro facilitated transport of settlers and supplies to New Mexico.

Who was hailed as the Father of the Nation?

Hidalgo is hailed as the Father of the Nation even though it was Agustin de Iturbide and not Hidalgo who achieved Mexican Independence in 1821. Shortly after gaining independence, the day to celebrate it varied between September 16, the day of Hidalgo's Grito, and September 27, the day Iturbide rode into Mexico City to end the war. Later, political movements would favor the more liberal Hidalgo over the conservative Iturbide, so that eventually September 16, 1810 became the officially recognized day of Mexican independence. The reason for this is that Hidalgo is considered to be "precursor and creator of the rest of the heroes of the (Mexican War of) Independence." Hidalgo has become an icon for Mexicans who resist tyranny in the country. Diego Rivera painted Hidalgo's image in half a dozen murals. José Clemente Orozco depicted him with a flaming torch of liberty and considered the painting among his best work. David Alfaro Siqueiros was commissioned by San Nicolas University in Morelia to paint a mural for a celebration commemorating the 200th anniversary of Hidalgo's birth. The town of his parish was renamed Dolores Hidalgo in his honor and the state of Hidalgo was created in 1869. Every year on the night of 15–16 September, the president of Mexico re-enacts the Grito from the balcony of the National Palace. This scene is repeated by the heads of cities and towns all over Mexico. The remains of Miguel Hidalgo y Costilla lie in the column of the Angel of Independence in Mexico City. Next to it is a lamp lit to represent the sacrifice of those who gave their lives for Mexican Independence.

In which year did Doniphan march with men from Missouri?

On February 8, 1847, Doniphan continued his march with 924 men mostly from Missouri; he accompanied a train of 315 wagons of a large commercial caravan heading to the state capital. Meanwhile, the Mexican forces in the state had time to prepare a defense against the Americans. About 20 miles (32 km) north of the capital where two mountain ranges join from east to west is the only pass into the capital; known as Sacramento Pass, this point is now part of present-day Chihuahua City. The Battle of Sacramento was the most important battle fought in the state of Chihuahua because it was the sole defense for the state capital. The battle ended quickly because of some devastating defensive errors from the Mexican forces and the ingenious strategic moves by the American forces. After their loss at the Battle of Sacramento, the remaining Mexican soldiers retreated south, leaving the city to American occupation. Almost 300 Mexicans were killed in the battle, as well as almost 300 wounded. The Americans also confiscated large amounts of Mexican supplies and took 400 Mexican soldiers prisoners of war. American forces maintained an occupation of the state capital for the rest of the Mexican–American War.

Who supported the reaction against the government?

The anti-clerical feeling was widespread, and Durango supported the initial reaction against the government at Mexico. In May 1832, José Urrea, a rising officer, supported the restoration of President Pedraza. On July 20, Governor Elorriaga was reinstated, and Baca along with the legislative minority were brought back to form a new legislature, which met on September 1. Chihuahua showed no desire to imitate the revolutionary movement and Urrea prepared to invade the state. Comandante-general J.J.Calvo threatened to retaliate, and a conflict seemed imminent. The entry of General Santa Anna into Mexico brought calm, as the leaders waited for clarity.

Who was deposed under threat from conservative forces?

Under threat from the conservative forces, Governor Terrazas was deposed, and the state legislature proclaimed martial law in the state in April 1864 and established Jesús José Casavantes as the new governor. In response, José María Patoni decided to march to Chihuahua with presidential support. Meanwhile, Maximilian von Habsburg, a younger brother of the Emperor of Austria, was proclaimed Emperor Maximilian I of Mexico on April 10, 1864 with the backing of Napoleon III and a group of Mexican conservatives. Before President Benito Juárez was forced to flee, Congress granted him an emergency extension of his presidency, which would go into effect in 1865 when his term expired, and last until 1867. At the same time, the state liberals and conservatives compromised to allow the popular Ángel Trías take the governorship; by this time the French forces had taken control over the central portions of the country and were making preparations to invade the northern states.

In which year was the new constitution ratified?

The state united behind the Plan of Ayutla and ratified the new constitution in 1855. The state was able to survive through the Reform War with minimal damage due to the large number of liberal political figures. The 1858 conservative movement did not succeed in the state even after the successful military campaign of the conservative Zuloaga with 1,000 men occupied the cities of Chihuahua and Parral. In August 1859, Zuloaga and his forces were defeated by the liberal Orozco and his forces; Orozco soon after deposed the state governor, but had to flee to Durango two months later. In the late 1860s the conservative General Cajen briefly entered the state after his campaign through the state of Jalisco and helped establish conservative politicians and ran out the liberal leaders Jesús González Ortega and José María Patoni. Cajen took possession of the state capital and established himself as governor; he brooked no delay in uniting a large force to combat the liberal forces which he defeated in La Batalla del Gallo. Cajen attained several advantages over the liberals within the state, but soon lost his standing due to a strong resurgence of the liberal forces within the state. The successful liberal leaders José María Patoni of Durango and J.E. Muñoz of Chihuahua quickly strengthened their standing by limiting the political rights of the clergy implementing the presidential decree. The state elected General Luis Terrazas, a liberal leader, as governor; he would continue to fight small battles within the state to suppress conservative uprisings during 1861.

Brincourt made preparations to invade which state?

After running imperial military affairs in the states of Coahuila and Durango, General Agustín Enrique Brincourt made preparations to invade the state of Chihuahua. On July 8, 1865 Brincourt crossed the Nazas River in northern Durango, heading toward Chihuahua. On July 22 Brincourt crossed the banks of Río Florido into Ciudad Jiménez; one day later he arrived at Valle de Allende where he sent Colonel Pyot with a garrison to take control of Hidalgo del Parral. Brincourt continued through Santa Rosalia de Camargo and Santa Cruz de Rosales. President Juárez remained in the state capital until August 5, 1865 when he left for El Paso del Norte (present-day Ciudad Juárez) due to evidence that the French were to attack the city. On the same day, the President named General Manuel Ojinaga the new governor and placed him in charge of all the republican forces. Meanwhile, General Villagran surprised the imperial forces in control of Hidalgo de Parral; after a short two-hour battle, Colonel Pyot was defeated and forced to retreat. At the Battle of Parral, the French lost 55 men to the Republican forces. On August 13, 1865, the French forces with an estimated 2,500 men arrived at the outskirts of Chihuahua City, and on August 15, 1865, General Brincourt defeated the republican forces, taking control of the state capital. Brincourt designated Tomás Zuloaga as Prefect of Chihuahua. Fearing the French would continue their campaign to El Paso del Norte, President Juárez relocated to El Carrizal, a secluded place in the mountains near El Paso del Norte, in August 1865, . It would have been easy for the French forces to continue in pursuit of President Juárez across the border, but they feared altercations with American forces. General François Achille Bazaine ordered the French troops to retreat back to the state of Durango after only reaching a point one days travel north of Chihuahua City. General Brincourt asked for 1,000 men to be left behind to help maintain control over the state, but his request was denied. After the death of General Ojinaga, the Republican government declared General Villagran in charge of the fight against the Imperial forces. The French left the state on October 29, 1865. President Juárez returned to Chihuahua City on November 20, 1865 and remained in the city until December 9, 1865 when he returned to El Paso del Norte. Shortly after the president left Chihuahua City, Terrazas was restored as governor of the state on December 11, 1865.

Where did Aguirre defeat the French forces?

General Aguirre moved to the deserts of the southeastern portion of the state and defeated the French forces in Parral, led by Colonel Cottret. By the middle of 1866, the state of Chihuahua was declared free of enemy control; Parral was the last French stronghold within the state. On June 17, 1866, President Juárez arrived in Chihuahua City and remained in the capital until December 10, 1866. During his two years in the state of Chihuahua, President Juárez passed ordinances regarding the rights of adjudication of property and nationalized the property of the clergy. The distance of the French forces and their allies allowed the Ministry of War, led by General Negrete, to reorganize the state's national guard into the Patriotic Battalion of Chihuahua, which was deployed to fight in the battle of Matamoros, Tamaulipas against the French. After a series of major defeats and an escalating threat from Prussia, France began pulling troops out of Mexico in late 1866. Disillusioned with the liberal political views of Maximilian, the Mexican conservatives abandoned him, and in 1867 the last of the Emperor's forces were defeated. Maximilian was sentenced to death by a military court; despite national and international pleas for amnesty, Juárez refused to commute the sentence. Maximilian was executed by firing squad on June 19, 1867.

The United States Congress declared war on Mexico on May 13, 1846 after only having a few hours to debate. Although President José Mariano Paredes's issuance of a manifesto on May 23 is sometimes considered the declaration of war, Mexico officially declared war by Congress on July 7. After the American invasion of New Mexico, Chihuahua sent 12,000 men led by Colonel Vidal to the border to stop the American military advance into the state. The Mexican forces being impatient to confront the American forces passed beyond El Paso del Norte about 20 miles (32 km) north along the Rio Grande. The first battle that Chihuahua fought was the battle of El Bracito; the Mexican forces consisting of 500 cavalry and 70 infantry confronted a force of 1,100–1,200 Americans on December 25, 1846. The battle ended badly by the Mexican forces that were then forced to retreat back into the state of Chihuahua. By December 27, 1846, the American forces occupied El Paso Del Norte. General Doniphan maintained camp in El Paso Del Norte awaiting supplies and artillery which he received in February 1847.

But the peace in the state did not last long, the elections of 1875 caused new hostilities. Ángel Trías led a new movement against the government in June 1875 and maintained control over the government until September 18, 1875 when Donato Guerra the orchestrator of the Revolution of the North was captured. Donato Guerra was assassinated in a suburb of Chihuahua City where he was incarcerated for conspiring with Ángel Trías. During October 1875 several locations were controlled by rebel forces, but the government finally regained control on November 25, 1875.

Under which governor was the education system unified?

Under Governor Miguel Ahumada, the education system in the state was unified and brought under tighter control by the state government, and the metric system was standardized throughout the state to replace the colonial system of weights and measures. On September 16, 1897, the Civilian Hospital of Chihuahua was inaugurated in Chihuahua City and became known among the best in the country. In 1901 the Heroes Theater (Teatro de los Héroes) opened in Chihuahua City. On August 18, 1904, Governor Terrazas was replaced by Governor Enrique C. Creel. From 1907 to 1911, the Creel administration succeeded in advancing the state's legal system, modernizing the mining industry, and raising public education standards. In 1908 the Chihuahuan State Penitentiary was built, and the construction on the first large scale dam project was initiated on the Chuviscar River. During the same time, the streets of Chihuahua City were paved and numerous monuments were built in Chihuahua City and Ciudad Juárez.

The internal stability was known as what?

Despite the internal stability (known as the paz porfiriana), modernization, and economic growth in Mexico during the Porfiriato from 1876 to 1910, many across the state became deeply dissatisfied with the political system. When Díaz first ran for office, he committed to a strict “No Re-election” policy in which he disqualified himself to serve consecutive terms. Eventually backtracking on many of his initial political positions Díaz became a de facto dictator. Díaz became increasingly unpopular due to brutal suppression of political dissidents by using the Rurales and manipulating the elections to solidify his political machine. The working class was frustrated with the Díaz regime due to the corruption of the political system that had increased the inequality between the rich and poor. The peasants felt disenfranchised by the policies that promoted the unfair distribution of land where 95% of the land was owned by the top 5%.

Orozco responded to whose letter to action?

In response to Madero's letter to action, Pascual Orozco (a wealthy mining baron) and Chihuahua Governor Abraham González formed a powerful military union in the north, taking military control of several northern Mexican cities with other revolutionary leaders, including Pancho Villa. Against Madero's wishes, Orozco and Villa fought for and won Ciudad Juárez. After militias loyal to Madero defeated the Mexican federal army, on May 21, 1911, Madero signed the Treaty of Ciudad Juárez with Díaz. It required that Díaz abdicate his rule and be replaced by Madero. Insisting on a new election, Madero won overwhelmingly in late 1911, and he established a liberal democracy and received support from the United States and popular leaders such as Orozco and Villa. Orozco eventually became disappointed with the Madero's government and led a rebellion against him. He organized his own army, called "Orozquistas"—also called the Colorados ("Red Flaggers")—after Madero refused to agree to social reforms calling for better working hours, pay and conditions. The rural working class, which had supported Madero, now took up arms against him in support of Orozco.

The situation became so tense that war with the United States seemed imminent. On April 22, 1914, on the initiative of Felix A. Sommerfeld and Sherburne Hopkins, Pancho Villa traveled to Juárez to calm fears along the border and asked President Wilson's emissary George Carothers to tell "Señor Wilson" that he had no problems with the American occupation of Veracruz. Carothers wrote to Secretary William Jennings Bryan: "As far as he was concerned we could keep Vera Cruz [sic] and hold it so tight that not even water could get in to Huerta and . . . he could not feel any resentment". Whether trying to please the U.S. government or through the diplomatic efforts of Sommerfeld and Carothers, or maybe as a result of both, Villa stepped out from under Carranza’s stated foreign policy.

Which state is the largest in the country by land?

The state of Chihuahua is the largest state in the country and is known as El Estado Grande (The Big State); it accounts for 12.6% of the land of Mexico. The area is landlocked by the states of Sonora to the west, Sinaloa to the south-west, Durango to the south, and Coahuila to the east, and by the U.S. states of Texas to the northeast and New Mexico to the north. The state is made up of three geologic regions: Mountains, Plains-Valleys, and Desert, which occur in large bands from west to east. Because of the different geologic regions there are contrasting climates and ecosystems.

Climate in the state depends mainly on what?

The climate in the state depends mainly in the elevation of the terrain. According to Köppen climate classification the state has five major climate zones. The Sierra Madre Occidental dominates the western part of the state; there are two main climates in this area: Subtropical Highland (Cfb) and Humid Subtropical (Cwa). There are some microclimates in the state due to the varying topology mostly found in the western side of the state. The two best known microclimates are: Tropical savanna climate (Aw) in deep canyons located in the extreme southern part of the state; Continental Mediterranean climate (Dsb) in the extremely high elevations of the Sierra Madre Occidental. Satellite image to the right shows the vegetation is much greener in the west because of the cooler temperatures and larger amounts of precipitation as compared to the rest of the state.

Villa and Carranza had different political goals causing Villa to become an enemy of Carranza. After Carranza took control in 1914, Villa and other revolutionaries who opposed him met at what was called the Convention of Aguascalientes. The convention deposed Carranza in favor of Eulalio Gutiérrez. In the winter of 1914 Villa's and Zapata's troops entered and occupied Mexico City. Villa was forced from the city in early 1915 and attacked the forces of Gen. Obregón at the Battle of Celaya and was badly defeated in the bloodiest battle of the revolution, with thousands dead. With the defeat of Villa, Carranza seized power. A short time later the United States recognized Carranza as president of Mexico. Even though Villa's forces were badly depleted by his loss at Celaya, he continued his fight against the Carranza government. Finally, in 1920, Obregón—who had defeated him at Celaya—finally reached an agreement with Villa end his rebellion.

Which months make up the pronounced rainy season in the steppe?

The plains at the foot of the Sierra Madre Occidental is an elongated mesa known as Altiplanicie Mexicana that exhibits a steppe climate and serves as a transition zone from the mountain climate in the western part of the state to the desert climate in the eastern side of the state. The steppe zone accounts for a third of the state's area, and it experiences pronounced dry and wet seasons. The pronounced rainy season in the steppe is usually observed in the months of July, August, and September. The steppe also encounters extreme temperatures that often reach over 100 °F in the summer and drop below 32 °F in the winter. The steppe zone is an important agriculture zone due to an extensive development of canals exploiting several rivers that flow down from the mountains. The steppe zone is the most populated area of the state.


The steppe reaches temperatures above what in the winter?


The steppe is important agriculturally because of what feature?


The mountain climate is found in which part of the state?


The state has great diversity thanks to the large number of what?

The state has a great diversity due to the large number of microclimates found and dramatic varying terrain. The flora throughout the Sierra Madre Occidental mountain range varies with elevation. Pine (Pinus) and oak (Quercus) species are usually found at an elevation of 2,000 m (6,560 ft) above sea level. The most common species of flora found in the mountains are: Pinus, Quercus, Abies, Ficus, Vachellia, Ipomoea, Acacia, Lysiloma, Bursera, Vitex, Tabebuia, Sideroxylon, Cordia, Fouquieria, Pithecellobium. The state is home to one of the largest variation species of the genus Pinus in the world. The lower elevations have a steppe vegetation with a variety of grasses and small bushes. Several species of Juniperus dot the steppe and the transition zone.

The state is home to one of the largest variation species of which genus?


Several species of which type dot the steppe and transition zone?


Which city in the state exceeds one million?

The state has one city with a population exceeding one million: Ciudad Juárez. Ciudad Juárez is ranked eighth most populous city in the country and Chihuahua City was ranked 16th most populous in Mexico. Chihuahua (along with Baja California) is the only state in Mexico to have two cities ranked in the top 20 most populated. El Paso and Ciudad Juárez comprise one of the largest binational metropolitan areas in the world with a combined population of 2.4 million. In fact, Ciudad Juárez is one of the fastest growing cities in the world in spite of the fact that it is "the most violent zone in the world outside of declared war zones". For instance, a few years ago the Federal Reserve Bank of Dallas published that in Ciudad Juárez "the average annual growth over the 10-year period 1990–2000 was 5.3 percent. Juárez experienced much higher population growth than the state of Chihuahua and than Mexico as a whole". Chihuahua City has one of the highest literacy rates in the country at 98%; 35% of the population is aged 14 or below, 60% 15-65, and 5% over 65. The growth rate is 2.4%. The 76.5% of the population of the state of Chihuahua live in cities which makes the state one of the most urbanized in Mexico.

French forces tried to capture the liberal government based where?

The French forces tried to subdue and capture the liberal government based in Saltillo. On September 21, 1864, José María Patoni and Jesús González Ortega lost against the French forces at the Battle of Estanzuelas; the supreme government led by President Juárez was forced to evacuate the city of Saltillo and relocate to Chihuahua. Juárez stopped in Ciudad Jiménez, Valle de Allende, and Hidalgo de Parral, in turn. He decreed Parral the capital of Mexico from October 2–5, 1864. Perceiving the threat from the advancing French forces, the president continued his evacuation through Santa Rosalía de Camargo, Santa Cruz de Rosales, and finally Chihuahua, Chihuahua. On October 12, 1864, the people of the state gave President Juárez an overwhelmingly supportive reception, led by Governor Ángel Trías. On October 15, 1864 the city of Chihuahua was declared the temporary capital of Mexico.

Benito Juarez was reelected in which year?

President Benito Juárez was re-elected in the general election of 1867 in which he received strong liberal support, especially in Chihuahua. Luis Terrazas was confirmed by the people of Chihuahua to be governor of the state. But soon after the election, President Juárez had another crisis on his hands; the Juárez administration was suspected to be involved in the assassination of the military chief José María Patoni executed by General Canto in August 1868. General Canto turned himself over to Donato Guerra. Canto was sentenced to death, but later his sentence changed to 10 years imprisonment. The sense of injustice gave rise to a new rebellion in 1869 that threatened the federal government. In response, the Juárez administration took drastic measures by temporarily suspending constitutional rights, but the governor of Chihuahua did not support this action. Hostilities continued to increase especially after the election of 1871 which was perceived to be fraudulent. A new popular leader arose among the rebels, Porfirio Díaz. The federal government was successful in quelling rebellions in Durango an Chihuahua. On July 18, 1872, President Juárez died from a heart attack; soon after, many of his supporters ceased the fighting. Peace returned to Chihuahua and the new government was led by Governor Antonio Ochoa (formerly a co-owner of the Batopilas silver mines) in 1873 after Luis Terrazas finished his term in 1872.

The Diaz administration allowed the elite to concentrate wealth by favoring what?

The Díaz administration made political decisions and took legal measures that allowed the elite throughout Mexico to concentrate the nation's wealth by favoring monopolies. During this time, two-fifths of the state's territory was divided among 17 rich families which owned practically all of the arable land in Chihuahua. The state economy grew at a rapid pace during the Porfiriato; the economy in Chihuahua was dominated by agriculture and mining. The Díaz administration helped Governor Luis Terrazas by funding the Municipal Public Library in Chihuahua City and passing a federal initiative for the construction of the railroad from Chihuahua City to Ciudad Júarez. By 1881, the Central Mexican Railroad was completed which connected Mexico City to Ciudad Juárez. In 1883 telephone lines were installed throughout the state, allowing communication between Chihuahua City and Aldama. By 1888 the telephone services were extended from the capital to the cites of Julimes, Meoqui, and Hidalgo del Parral; the telecommunication network in the state covered an estimated 3,500 kilometers. The need of laborers to construct the extensive infrastructure projects resulted in a significant Asian immigration, mostly from China. Asian immigrants soon become integral to the state economy by opening restaurants, small grocery stores, and hotels. By the end of the Terrazas term, the state experienced an increase in commerce, mining, and banking. When the banks were nationalized, Chihuahua became the most important banking state in Mexico.

The end of the Porfiriato came in 1910 with the beginning of the Mexican Revolution. Díaz had stated that Mexico was ready for democracy and he would step down to allow other candidates to compete for the presidency, but Díaz decided to run again in 1910 for the last time against Francisco I. Madero. During the campaign Díaz incarcerated Madero on election day in 1910. Díaz was announced the winner of the election by a landslide, triggering the revolution. Madero supporter Toribio Ortega took up arms with a group of followers at Cuchillo Parado, Chihuahua on November 10, 1910.

The uneasy alliance between whom eventually won rebels the victory?

The uneasy alliance of Carranza, Obregón, Villa, and Zapata eventually led the rebels to victory. The fight against Huerta formally ended on August 15, 1914, when Álvaro Obregón signed a number of treaties in Teoloyucan in which the last of Huerta's forces surrendered to him and recognized the constitutional government. On August 20, 1914, Carranza made a triumphal entry into Mexico City. Carranza (supported by Obregón) was now the strongest candidate to fill the power vacuum and set himself up as head of the new government. This government successfully printed money, passed laws, etc.

Which is the main mountain range in the state?

The main mountain range in the state is the Sierra Madre Occidental reaching a maximum altitude of 10,826 ft (3,300 m) known as Cerro Mohinora. Mountains account for one third of the state's surface area which include large coniferous forests. The climate in the mountainous regions varies Chihuahua has more forests than any other state in Mexico making the area a bountiful source of wood; the mountainous areas are rich in minerals important to Mexico's mining industry. Precipitation and temperature in the mountainous areas depends on the elevation. Between the months of November and March snow storms are possible in the lower elevations and are frequent in the higher elevations. There are several watersheds located in the Sierra Madre Occidental all of the water that flows through the state; most of the rivers finally empty into the Río Grande. Temperatures in some canyons in the state reach over 100 °F in the summer while the same areas rarely drop below 32 °F in the winter. Microclimates found in the heart of the Sierra Madre Occidental in the state could be considered tropical, and wild tropical plants have been found in some canyons. La Barranca del Cobre, or Copper Canyon, a spectacular canyon system larger and deeper than the Grand Canyon; the canyon also contains Mexico's two tallest waterfalls: Basaseachic Falls and Piedra Volada. There are two national parks found in the mountainous area of the state: Cumbres de Majalca National Park and Basaseachic Falls National Park.

Which state has more forests than any other?


Precipitation and temperature in the mountainous region depend on what?


What type of plants can be found in some canyons?


In the far eastern part of the state the Chihuahuan Desert dominates due to low precipitation and extremely high temperatures; some areas of the eastern part of the state are so dry no vegetation is found like the Sand Dunes of Samalayuca. There are two distinctive climate zones found in the eastern part of the state: Hot Desert (BWh) and Cool Desert (BWk) which are differentiated by average annual temperature due to differences in elevation. There is a transition zone in the middle of the state between the two extremely different climates from the east and west; this zone is the Steppe characterized by a compromise between juxtaposed climate zones.

Who invited Canadians to resettle in Mexico during the Mexican Revolution?

During the Mexican Revolution, Álvaro Obregón invited a group of Canadian German-speaking Mennonites to resettle in Mexico. By the late 1920s, some 7,000 had immigrated to Chihuahua State and Durango State, almost all from Canada, only a few from the U.S. and Russia. Today, Mexico accounts for about 42% of all Mennonites in Latin America. Mennonites in the country stand out because of their light skin, hair, and eyes. They are a largely insular community that speaks a form of German and wear traditional clothing. They own their own businesses in various communities in Chihuahua, and account for about half of the state's farm economy, excelling in cheese production.

Agriculture varies across the state because of the variation in what?

Agriculture is a relatively small component of the state's economy and varies greatly due to the varying climate across the state. The state ranked first in Mexico for the production of the following crops: oats, chile verde, cotton, apples, pecans, and membrillo. The state has an important dairy industry with large milk processors throughout the state. Delicias is home to Alpura, the second-largest dairy company in Mexico. The state has a large logging industry ranking second in oak and third in pine in Mexico. The mining industry is a small but continues to produce large amounts of minerals. The state ranked first place in the country for the production of lead with 53,169 metric tons. Chihuahua ranked second in Mexico for zinc at 150,211 metric tons, silver at 580,271 kg, and gold at 15,221.8 kg.

What was the first province of northern New Spain to be explored?

Nueva Vizcaya (New Biscay) was the first province of northern New Spain to be explored and settled by the Spanish. Around 1528, a group of Spaniard explorers, led by Álvar Núñez Cabeza de Vaca, first entered the actual territory of what is now Chihuahua. The conquest of the territory lasted nearly one century, and encountered fierce resistance from the Conchos tribe, but the desire of the Spanish Crown to transform the region into a bustling mining center led to a strong strategy to control the area.

The Spanish crown wanted to turn the region into what type of industry?


Which tribe resisted fiercely this conquest?


Hidalgo was turned over to the Bishop of Durango, Francisco Gabriel de Olivares, for an official defrocking and excommunication on July 27, 1811. He was then found guilty of treason by a military court and executed by firing squad on July 30 at 7 in the morning. Before his execution, he thanked his jailers, Private Soldiers Ortega and Melchor, in letters for their humane treatment. At his execution, Hidalgo placed his right hand over his heart to show the riflemen where they should aim. He also refused the use of a blindfold. His body, along with the bodies of Allende, Aldama and José Mariano Jiménez were decapitated, and the heads were put on display on the four corners of the Alhóndiga de Granaditas in Guanajuato. The heads remained there for ten years until the end of the Mexican War of Independence to serve as a warning to other insurgents. Hidalgo's headless body was first displayed outside the prison but then buried in the Church of St Francis in Chihuahua. Those remains would later be transferred in 1824 to Mexico City.


How was Hidalgo executed after having been found guilty?


Hidalgo refused the use of what during his execution?


In which state was Hidalgo's headless body buried?


During which year was the federal government unstable?

Because of the general instability of the federal government during 1828, the installation of the new legislature did not take place until the middle of the following year. It was quickly dissolved by Governor Santiago de Baca Ortiz, who replaced it with a more pronounced Yorkino type. When Guerrero's liberal administration was overthrown in December, Gaspar de Ochoa aligned with Anastasio Bustamante, and in February 1830, organized an opposition group that arrested the new governor, F. Elorriaga, along with other prominent Yorkinos. He then summoned the legislature, which had been dissolved by Baca. The civil and military authorities were now headed by J. A. Pescador and Simón Ochoa.

Who now headed the civil and military authorities?


Military command was given to whom based on his firmness?

Comandante general Simón Elías González, was nominated governor and military command was given to Colonel J.J. Calvo, whose firmness had earned well-merited praise. The state was in the midst of a war with the Apaches, which became the focus of all their energy and resources. After a review of the situation, Simón Elías González declared that the interests of the territory would be best served by uniting the civil and military power, at least while the campaign lasted. He resigned under opposition, but was renominated in 1837.


Who declared the state's civil and military forces should be combined during the campaign?


In which year did Gonzalez receive renomination?


What group continuously attacked Mexican settlements?

During the American occupation of the state, the number of Indian attacks was drastically reduced, but in 1848 the attacks resumed to such a degree that the Mexican officials had no choice but to resume military projects to protect Mexican settlements in the state. Through the next three decades the state faced constant attacks from indigenous on Mexican settlements. After the occupation the people of the state were worried about the potential attack from the hostile indigenous tribes north of the Rio Grande; as a result a decree on July 19, 1848, the state established 18 military colonies along the Rio Grande. The new military colonies were to replace the presidios as population centers to prevent future invasions by indigenous tribes; these policies remained prominent in the state until 1883. Eventually the state replaced the old state security with a state policy to form militias organized with every Mexican in the state capable to serve between the ages of 18 and 55 to fulfill the mandate of having six men defending for every 1000 residents.

Which political forces maintained strong control over the state until shortly after French intervention?

The liberal political forces maintained strong control over the state government until shortly after the French Intervention which turned the tables in favor to the conservative forces once again. The intervention had serious repercussions for the state of Chihuahua. President Juárez, in an effort to organize a strong defense against the French, decreed a list of national guard units that every state had to contribute to the Ministry of War and the Navy; Chihuahua was responsible for inducting 2,000 men. Regaining power, Governor Luis Terrazas assigned the First Battalion of Chihuahua for integration into the national army led by General Jesús González Ortega; the battalion was deployed to Puebla. After the defeat of the army in Puebla, the Juárez administration was forced to abandon Mexico City; the president retreated further north seeking refuge in the state of Chihuahua.

To where was the battalion first deployed?


Juarez again based his government in which state?

President Juárez once again based his government in the state of Chihuahua and it served as the center for the resistance against the French invasion throughout Mexico. On March 25, 1866, a battle ensued in the Plaza de Armas in the center of Chihuahua City between the French imperial forces that were guarding the plaza and the Republican forces led by General Terrazas. Being completely caught off guard, the French imperial forces sought refuge by bunkering themselves in the Cathedral of the Holy Cross, Our Lady of Regla, and St Fancis of Assisi and made it almost impossible to penetrate their defenses. General Terrazas then decided to fire a heavy artillery barrage with 8 kg cannonballs. The first cannon fired hit a bell in the tower of the church, instantly breaking it in half; soon after, 200 men of the imperial army forces surrendered. The republican forces had recovered control over the state capital. The bell in the church was declared a historical monument and can be seen today in the Cathedral. By April 1866, the state government had established a vital trading route from Chihuahua City to San Antonio, Texas; the government began to replenish their supplies and reinforce their fight against the Imperial forces.

The officials in Mexico reduced the price of what food from six cents to two cents per pound?

The officials in Mexico City reduced the price of corn from six cents to two cents a pound. The northern portion of the state continued to decline economically which led to another revolt led by G. Casavantes in August 1879; Governor Trías was accused of misappropriation of funds and inefficient administration of the state. Casavantes took the state capital and occupied it briefly; he was also successful in forcing Governor Trías to exile. Shortly afterwards, the federal government sent an entourage led by Treviño; Casavantes was immediately ordered to resign his position. Casavantes declared political victory as he was able to publicly accuse and depose Governor Trías. At the same time the states of Durango and Coahuila had a military confrontation over territorial claims and water rights; this altercation between the state required additional federal troops to stabilize the area. Later a dispute ensued again among the states of Coahuila, Durango, and Chihuahua over the mountain range area known as Sierra Mojada, when large deposits of gold ore was discovered. The state of Chihuahua officially submitted a declaration of protest in May 1880 that shortly after was amicably settled. Despite the difficulties at the beginning, Díaz was able to secure and stabilize the state, which earned the confidence and support of the people.

Casavantes was successful in getting which Governor to exile?


Durango and Coahuila had a military confrontation over what natural resource?


Who was able to secure and stabilize the state eventually and gain the support of the people?


The state's economy was largely defined by these two industries.

A handful of families owned large estates (known as haciendas) and controlled the greater part of the land across the state while the vast majority of Chihuahuans were landless. The state economy was largely defined by ranching and mining. At the expense of the working class, the Díaz administration promoted economic growth by encouraging investment from foreign companies from the United Kingdom, France, Imperial Germany and the United States. The proletariat was often exploited, and found no legal protection or political recourse to redress injustices.


Diaz promoted economic growth by encouraging investment from foreign companies at the expense of what group?


What was the name of the large estates owned by wealthy families?


This group was often exploited and had no legal protection or recourse.


On March 26, 1913, Venustiano Carranza issued the Plan de Guadalupe, which refused to recognize Huerta as president and called for war between the two factions. Soon after the assassination of President Madero, Carranza returned to Mexico to fight Huerta, but with only a handful of comrades. However, by 1913 his forces had swelled into an army of thousands, called the División del Norte (Northern Division). Villa and his army, along with Emiliano Zapata and Álvaro Obregón, united with Carranza to fight against Huerta. In March 1914 Carranza traveled to Ciudad Juárez, which served as rebellion's capital for the remainder of the struggle with Huerta. In April 1914 U.S. opposition to Huerta had reached its peak, blockading the regime's ability to resupply from abroad. Carranza trying to keep his nationalistic credentials threatened war with the United States. In his spontaneous response to U.S. President Woodrow Wilson Carranza asked "that the president withdraw American troops from Mexico.”

Carranza threatened war with what country in order to maintain credibility nationally?


The desert zone accounts for how much of the state's surface area?

The desert zone also accounts for about a third of the state's surface area. The Chihuahuan Desert is an international biome that also extends into the neighboring Mexican state of Coahuila and into the U.S. states of Texas and New Mexico. The desert zone is mainly of flat topography with some small mountain ranges that run north to south. The desert in the state varies slightly with a small variant in climate. The lower elevations of the desert zone are found in the north along the Rio Grande which experience hotter temperatures in the summer and winter while the southern portion of the desert zone experiences cooler temperatures due to its higher elevation. The Samalayuca dunes cover an area of about 150 km2; it is an impressive site of the Chihuahuan Desert and is a protected area by the state due to unique species of plants and animals.

Lower elevations and higher temperature are found in which region of the state; north, south, east, or west?


Which well-known river runs in the northern part of the state?


The fauna in the state is just as diverse as the flora and varies greatly due to the large contrast in climates. In the mountain zone of the state the most observed mammals are: Mexican fox squirrel (Sciurus nayaritensis), antelope jackrabbit (Lepus alleni), raccoon (Procyon lotor), hooded skunk (Mephitis macroura), wild boar (Sus scrofa), collared peccary (Pecari tajacu), white-tailed deer (Odocoileus virginianus), mule deer Odocoileus hemionus, American bison Bison bison, cougar (Puma concolor), eastern cottontail Sylvilagus floridanus, North American porcupine Erethizon dorsatum, bobcat Lynx rufus, Mexican wolf Canis lupus baileyi, and coyote Canis latrans. American black bear Ursus americanus is also found but in very small numbers. The Mexican wolf, once abundant, has been extirpated. The main cause of degradation has been grazing. Although there are many reptilian species in the mountains the most observed species include: Northern Mexican pine snake, Pituophis deppei jani, Texas horned lizard (Phrynosoma cornutum), rock rattlesnake (Crotalus lepidus), black-tailed rattlesnake (Crotalus molossus), and plateau tiger salamander Ambystoma velasci, one of possibly many amphibians to be found in the mountains.

The last census in Mexico that asked for race was carried out in which year?

The last census in Mexico that asked for an individual's race, which was taken in 1921, indicated that 50.09% of the population identified as Mestizo (mixed Amerindian and European descent). The second-largest group was whites at 36.33% of the population. The third-largest group was the "pure indigenous" population, constituting 12.76% of the population. The remaining 0.82% of the population of Chihuahua was considered "other", i.e., neither Mestizo, indigenous, nor white. The most important indigenous tribes of the state of Chihuahua are:

What agreement sparked industrial development during the 1990s?

During the 1990s after NAFTA was signed, industrial development grew rapidly with foreign investment. Large factories known as maquiladoras were built to export manufactured goods to the United States and Canada. Today, most of the maquiladoras produce electronics, automobile, and aerospace components. There are more than 406 companies operating under the federal IMMEX or Prosec program in Chihuahua. The large portion of the manufacturing sector of the state is 425 factories divided into 25 industrial parks accounting for 12.47% of the maquiladoras in Mexico, which employ 294,026 people in the state. While export-driven manufacturing is one of the most important components of the state's economy, the industrial sector is quite diverse and can be broken down into several sectors, which are: electronics, agro-industrial, wood base manufacturing, mineral, and biotech. Similar to the rest of the country, small businesses continue to be the foundation of the state’s economy. Small business employs the largest portion of the population.[citation needed]

Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.


Each persons perception of sound is called?


This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C♯ (61) can be labeled 60.5.


Semitones in linear pitch are what size?


An equal-tempered semitone is subdivided into how many cents?


The pitch halfway between C (60) and C♯ (61) is labeled what?


What is the most common method of organization?

The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).


The pitch ratio between any two successive notes is?


All these different methods have what in common?


Pitch is the auditory attribute to what?

According to the American National Standards Institute, pitch is the auditory attribute of sound according to which sounds can be ordered on a scale from low to high. Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation. Despite that, the idiom relating vertical height to sound pitch is shared by most languages. At least in English, it is just one of many deep conceptual metaphors that involve up/down. The exact etymological history of the musical sense of high and low pitch is still unclear. There is evidence that humans do actually perceive that the source of a sound is slightly higher or lower in vertical space when the sound frequency is increased or decreased.


This produces many modes of vibration that occur simultaneously?

A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once. The vibration with the lowest frequency is called the fundamental frequency; the other frequencies are overtones. Harmonics are an important class of overtones with frequencies that are integer multiples of the fundamental. Whether or not the higher frequencies are integer multiples, they are collectively called the partials, referring to the different parts that make up the total spectrum.


A listener can hear how many frequencies at once?


Harmonics are an important class of what?


Integer multiples are collectively called?


The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon the observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones, also known as upper partials, harmonic or otherwise. A complex tone composed of two sine waves of 1000 and 1200 Hz may sometimes be heard as up to three pitches: two spectral pitches at 1000 and 1200 Hz, derived from the physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental, which is often the greatest common divisor of the frequencies present.

The just-noticeable difference, at which a change is perceived depends on what?

The just-noticeable difference (jnd) (the threshold at which a change is perceived) depends on the tone's frequency content. Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies. The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120.


What is the range of perceptible pitch steps to human hearing?


Which drum has a higher perceived pitch even though they both have indefinite pitch?

It is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A special type of pitch often occurs in free nature when sound reaches the ear of an observer directly from the source, and also after reflecting off a sound-reflecting surface. This phenomenon is called repetition pitch, because the addition of a true repetition of the original sound to itself is the basic prerequisite.


Repetition pitch is caused by what phenomenon?


It is possible and often easy to roughly discern the relative pitches of two sounds of what?


The notion of pitch is insensitive to what?

For example, one might refer to the A above middle C as a', A4, or 440 Hz. In standard Western equal temperament, the notion of pitch is insensitive to "spelling": the description "G4 double sharp" refers to the same pitch as A4; in other temperaments, these may be distinct pitches. Human perception of musical intervals is approximately logarithmic with respect to fundamental frequency: the perceived interval between the pitches "A220" and "A440" is the same as the perceived interval between the pitches A440 and A880. Motivated by this logarithmic perception, music theorists sometimes represent pitches using a numerical scale based on the logarithm of fundamental frequency. For example, one can adopt the widely used MIDI standard to map fundamental frequency, f, to a real number, p, as follows


The description "G4 double sharp" refers to the same pitch as what?


Human perception of musical intervals is approximately what?


Music theorist represent pitches using what kind of scale?


The precise way this temporal structure helps code for pitch at higher levels is based on what?

Temporal theories offer an alternative that appeals to the temporal structure of action potentials, mostly the phase-locking and mode-locking of action potentials to frequencies in a stimulus. The precise way this temporal structure helps code for pitch at higher levels is still debated, but the processing seems to be based on an autocorrelation of action potentials in the auditory nerve. However, it has long been noted that a neural mechanism that may accomplish a delay—a necessary operation of a true autocorrelation—has not been found. At least one model shows that a temporal delay is unnecessary to produce an autocorrelation model of pitch perception, appealing to phase shifts between cochlear filters; however, earlier work has shown that certain sounds with a prominent peak in their autocorrelation function do not elicit a corresponding pitch percept, and that certain sounds without a peak in their autocorrelation function nevertheless elicit a pitch. To be a more complete model, autocorrelation must therefore apply to signals that represent the output of the cochlea, as via auditory-nerve interspike-interval histograms. Some theories of pitch perception hold that pitch has inherent octave ambiguities, and therefore is best decomposed into a pitch chroma, a periodic value around the octave, like the note names in western music—and a pitch height, which may be ambiguous, that indicates the octave the pitch is in.


Is a temporal delay necessary to produce an autocorrelation model of pitch perception?


Pitch perception has inherent octave what?


When did King Richard I begin his reign?

The motif of the England national football team has three lions passant guardant, the emblem of King Richard I, who reigned from 1189 to 1199. The lions, often blue, have had minor changes to colour and appearance. Initially topped by a crown, this was removed in 1949 when the FA was given an official coat of arms by the College of Arms; this introduced ten Tudor roses, one for each of the regional branches of the FA. Since 2003, England top their logo with a star to recognise their World Cup win in 1966; this was first embroidered onto the left sleeve of the home kit, and a year later was moved to its current position, first on the away shirt.

What color were England's first away kits?

Although England's first away kits were blue, England's traditional away colours are red shirts, white shorts and red socks. In 1996, England's away kit was changed to grey shirts, shorts and socks. This kit was only worn three times, including against Germany in the semi-final of Euro 96 but the deviation from the traditional red was unpopular with supporters and the England away kit remained red until 2011, when a navy blue away kit was introduced. The away kit is also sometimes worn during home matches, when a new edition has been released to promote it.

In what year was England most recently eliminated from FIFA World Cup contention?

England failed to qualify for the World Cup in 1974, 1978 and 1994. The team's earliest exit in the competition itself was its elimination in the first round in 1950, 1958 and most recently in the 2014 FIFA World Cup, after being defeated in both their opening two matches for the first time, versus Italy and Uruguay in Group D. In 1950, four teams remained after the first round, in 1958 eight teams remained and in 2014 sixteen teams remained. In 2010, England suffered its most resounding World Cup defeat (4–1 to Germany) in the Round of 16, after drawing with the United States and Algeria and defeating Slovenia 1–0 in the group stage.

Their first ever defeat on home soil to a foreign team was an 0–2 loss to the Republic of Ireland, on 21 September 1949 at Goodison Park. A 6–3 loss in 1953 to Hungary, was their second defeat by a foreign team at Wembley. In the return match in Budapest, Hungary won 7–1. This still stands as England's worst ever defeat. After the game, a bewildered Syd Owen said, "it was like playing men from outer space". In the 1954 FIFA World Cup, England reached the quarter-finals for the first time, and lost 4–2 to reigning champions Uruguay.

In what year did Capello resign as England's football manager?

In February 2012, Capello resigned from his role as England manager, following a disagreement with the FA over their request to remove John Terry from team captaincy after accusations of racial abuse concerning the player. Following this, there was media speculation that Harry Redknapp would take the job. However, on 1 May 2012, Roy Hodgson was announced as the new manager, just six weeks before UEFA Euro 2012. England managed to finish top of their group, winning two and drawing one of their fixtures, but exited the Championships in the quarter-finals via a penalty shoot-out, this time to Italy.

Who is the current team manager of England's football team?


To begin with, England had no permanent home stadium. They joined FIFA in 1906 and played their first ever games against countries other than the Home Nations on a tour of Central Europe in 1908. Wembley Stadium was opened in 1923 and became their home ground. The relationship between England and FIFA became strained, and this resulted in their departure from FIFA in 1928, before they rejoined in 1946. As a result, they did not compete in a World Cup until 1950, in which they were beaten in a 1–0 defeat by the United States, failing to get past the first round in one of the most embarrassing defeats in the team's history.

Sven-Göran Eriksson took charge of the team between 2001 and 2006, and was the first non–English manager of England. Despite controversial press coverage of his personal life, Eriksson was consistently popular with the majority of fans.[citation needed] He guided England to the quarter-finals of the 2002 FIFA World Cup, UEFA Euro 2004, and the 2006 FIFA World Cup. He lost only five competitive matches during his tenure, and England rose to an No.4 world ranking under his guidance. His contract was extended by the Football Association by two years, to include UEFA Euro 2008. However, it was terminated by them at the 2006 FIFA World Cup's conclusion.

Commentated broadcasts of all England matches air on what network?

All England matches are broadcast with full commentary on BBC Radio 5 Live. From the 2008–09 season until the 2017–18 season, England's home and away qualifiers, and friendlies both home and away are broadcast live on ITV (often with the exception of STV, the ITV affiliate in central and northern Scotland). England's away qualifiers for the 2010 World Cup were shown on Setanta Sports until that company's collapse. As a result of Setanta Sports's demise, England's World Cup qualifier in Ukraine on 10 October 2009 was shown in the United Kingdom on a pay-per-view basis via the internet only. This one-off event was the first time an England game had been screened in such a way. The number of subscribers, paying between £4.99 and £11.99 each, was estimated at between 250,000 and 300,000 and the total number of viewers at around 500,000.

Where were Augustus Chapman Allen and John Kirby Allen from?

In August 1836, two real estate entrepreneurs—Augustus Chapman Allen and John Kirby Allen—from New York, purchased 6,642 acres (26.88 km2) of land along Buffalo Bayou with the intent of founding a city. The Allen brothers decided to name the city after Sam Houston, the popular general at the Battle of San Jacinto, who was elected President of Texas in September 1836. The great majority of slaves in Texas came with their owners from the older slave states. Sizable numbers, however, came through the domestic slave trade. New Orleans was the center of this trade in the Deep South, but there were slave dealers in Houston. Thousands of enslaved African-Americans lived near the city before the Civil War. Many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs. In 1860 forty-nine percent of the city's population was enslaved. A few slaves, perhaps as many as 2,000 between 1835 and 1865, came through the illegal African trade. Post-war Texas grew rapidly as migrants poured into the cotton lands of the state. They also brought or purchased enslaved African Americans, whose numbers nearly tripled in the state from 1850 to 1860, from 58,000 to 182,566.

What event cause shipping activities to be suspended?

When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of non-discrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years.

In what year did the space shuttle Challenger explode after launch?

One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.

What materials are underpinning the land surface of Houston?

Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.

Downtown Houston consisted of what type of building in the 1960's?

In the 1960s, Downtown Houston consisted of a collection of mid-rise office structures. Downtown was on the threshold of an energy industry–led boom in 1970. A succession of skyscrapers were built throughout the 1970s—many by real estate developer Gerald D. Hines—culminating with Houston's tallest skyscraper, the 75-floor, 1,002-foot (305 m)-tall JPMorgan Chase Tower (formerly the Texas Commerce Tower), completed in 1982. It is the tallest structure in Texas, 15th tallest building in the United States, and the 85th tallest skyscraper in the world, based on highest architectural feature. In 1983, the 71-floor, 992-foot (302 m)-tall Wells Fargo Plaza (formerly Allied Bank Plaza) was completed, becoming the second-tallest building in Houston and Texas. Based on highest architectural feature, it is the 17th tallest in the United States and the 95th tallest in the world. In 2007, downtown Houston had over 43 million square feet (4,000,000 m²) of office space.
