Figure 1.--Most of Mexico's volcanos like other volcanoes are long established. Amazinglky, the Parícutin volcano east of Mexico City emerged out Dionisio Pulido's corn field (February 20, 1943). High seismic activity, subteranean noise, and tremors were registered in the Sun Juan Parangaricutiro area before Pulido and his family witnessed the birth of the volcano. This is the volcano a few days later after the cone had begun to form. Volcanos have played a more important role in the creation of Mexico than is fully understood.
Mexico is the northernmost constituent of Latin America and the most populous Spanish-speaking country in the world. Mexico when discussing geography has been called a land of extremes. The country is domimatd by two parallel mountain chains with rugged mountains and deep canyons skirting both coasts. Over half the countries lies at altitudes above 1,000 meters. The Sierra Madre Oriental is inland from the Gulf of Mexcico coast. The Sierra Madre Occidental with much higher peaks skirts the Pacific Coast and extends north into the United States. There are narrow coastal lowlands. In between is the rugged central platau, the country's central land mass with smaller mountain ranges. There are mineral resources in these ranges, including copper and silver. The north constiututes about 40 percent of Mexican territory. Most of it is arid including border deserts which is why in addition to hostile Native American tribesthat the north,including Texas, was not heavily populated in the era before the Mexican-Amrican War (1846-48). Mexico has a 5,000-kilometer border with the United States. Much of it is defined by the meandering Río Bravo del Norte (the Rio Grande) from Ciudad Juárez east to the Gulf of Mexico. Westward from Ciudad Juárez to the Pacific Ocedan there are natural and artificial markers. Mexico has many small rivers, but few important ones. Most have short runs from the Sierra Madere Oriente into the Gulf of MNexici=on and Sierrra Madre Occidental into the Pacfiic. The Rio Bravo is the longest river, but the volume is realtively low. The Mexican landmass narrows as it moves in a southeasterly direction from the United States border toward Central America. In the south bordering on Guatemala are dense rain forests--the homeland of the Maya. There are two appendages. The Yucantan Peninsuka in the southeast and Baja Califoirnia in the far west. The Yucatan lies between the Gulf of Mexico and the Caribbean Sea. It along with the American Florida peninsula forms the Gulf. It is where the Spanish first landed and encountered the Maya before launching the conquest of Mexico at the time dominated by the Aztecs centered in Tenochtitlan (modern Mexico City). The Conquistadores who grew up in the gritty villages of Extrenmadura were amazed at the magifiicance of the Aztec city. The Aztec capital doiminated the Valley of Mexico and the precious. lfe giving waters of Lake Texcoco. The Pacific Ring of Fire runs across southern Mexico into the Pacific (Trans-Mexican Volcanic Belt) and then heads northwest up the Pacific coast. The snow covered Pico de Orizaba (Citlaltépetl) south of Mexico City is an inactive stratovolcano, the highest mountain in Mexico and the third highest in North America. Nearby Popocatépetl is the highest active volcano. Most Mexicans volcanos are long established, one Parícutin further west rose out of a corn field in 1943 (figure 1).
Location
Mexico is the northernmost constituent of Latin America and the most populous Spanish-speaking country in the world. Mexico is geologically part of north America, but culturally more relzated to Lzatin America dominated by Iberian culture. The morterly locastion also means that it is the Latin American country bordering on the United States. That has had profound historical and economic consequences.
Extremes
Mexico when discussing geography has been called a land of extremes. The country is domimatd by two parallel mountain chains with rugged mountains and deep canyons skirting both coasts. And in cebntral Mecxico, volcanos from coast to coast. There are sweltering tropical, lowlands and snow ciovered peaks.
Mountains
Over half the countries lies at altitudes above 1,000 meters. The Sierra Madre Oriental is inland from the Gulf of Mexcico coast. The Sierra Madre Occidental with much higher peaks skirts the Pacific Coast and extends north into the United States. There are narrow coastal lowlands. In between is the rugged central platau, the country's central land mass with smaller mountain ranges. There are mineral resources in these ranges, including copper and silver. The Pacific Ring of Fire runs across southern Mexico into the Pacific (Trans-Mexican Volcanic Belt) and then heads northwest up the Pacific coast. . The snow covered Pico de Orizaba (Citlaltépetl) south of Mexico City is an inactive stratovolcano, the highest mountain in Mexico and the third highest in North America. Nearby Popocatépetl is the highest active volcano. Most Mexicans volcanos are long established, one Parícutin further west rose out of a corn field in 1943 (figure 1).
Regions
The country's nothern, cental, and southern regions are very differemt.
The north constiututes about 40 percent of Mexican territory. Most of it is arid including border deserts which is why in addition to hostile Native American tribesthat the north, including Texas, was not heavily populated in the era before the Mexican-Amrican War (1846-48). Northerrn Mexico is still lightly populated, altough griowing because industru there can be tied into the American economy. .
The central region in a band eastb and west of Mexicon city has the coytry;s higest peaks as a result of a string of volcanos. This is the heart of Meso-America and continues to be heart of Mexico today. Great Amer-Indian civililaztions rose there. It was one of the six regions world wide where agriculture independent arose. Most were river vallies. Latin America was a little different, more assocted with volcanos. Meso-America is more assocyted with the volcanic band across central America. And where the Amer-Indians develooped the world's most imprtant agriculturalm plant--corn. Southern Mexico is made up of tropical lowlands. The Mexican landmass narrows as it moves in a southeasterly direction from the United States border toward Central America. In the south bordering on Guatemala are dense rain forests--the homeland of the Maya. There are two appendages. The Yucantan Peninsuka in the southeast and Baja Califoirnia in the far west. The Yucatan lies between the Gulf of Mexico and the Caribbean Sea. It along with the American Florida peninsula forms the Gulf of Mexixo. .
Bodies of Water
Mexico has a 5,000-kilometer border with the United States. Much of it is defined by the meandering Río Bravo del Norte (the Rio Grande) from Ciudad Juárez east to the Gulf of Mexico. Westward from Ciudad Juárez to the Pacific Ocedan there are natural and artificial markers. Mexico has many small rivers, but few imprtant ones. There are important lakes, but no navigable rivers. That was of huge imprtance in the era before railroads. Most have short, steep runs from the Sierra Madere Oriente into the Gulf of Mexicn and Sierrra Madre Occidental into the Pacfic. The Rio Bravo is the longest river, but the volume is realtively low.
Demographics
Mexican demographics are dominated by as simple phenomenon. Most of the population lives in a narrow population band east and west of Mexico City. This is where Cortez landed to begin the conquest of the Aztec Empire. The Aztec capital was Tenochtitlan (modern Mexico City) located on the lakes of the Central Valley. The Conquistadores who grew up in the gritty villages of Extrenmadura were amazed at the magificance of the Aztec city. The Aztec capital doiminated the Valley of Mexico and the narrow band across central Mexico. This was where the bulk of the population was located. This was and continued to be the case for one primary reason--the volcanos. The volcanos not only created rich soils, but elevated the landscape so we don't have the problems associated with tropical agriculture. For most of recorded time, agriculture was the primary way of making a living and this narrow band was the only area of Mexico with high agricultural productivity. The northrrn areas were arid. The north was very lightly populated by Mexicams. most of the population was Amer-Indians. The southerrn areas were tropical lowlands with low garicultural productivity.
