Which Sierra Madre range is in the West?
The largely volcanic Sierra Madre Occidental, which forms the western border of the Mexican Plateau, has an average elevation of 8,000–9,000 feet (2,400–2,700 metres) and extends roughly 700 miles (1,100 km) from north to south.
Where do the Sierra Madre mountains start and end?
The Sierra Madre de Oaxaca mountain range is located in southern Mexico, primarily in the state of Oaxaca, extending north into the states of Puebla and Veracruz. The mountain range begins at Pico de Orizaba and extends in a southeasterly direction for 300 km (190 miles) until reaching the Isthmus of Tehuantepec.
What lies between the Sierra Madre mountains?
Mexican Plateau
The Mexican Plateau, which averages 1,100 metres (3,600 ft) in elevation, lies between the Sierra Madre Oriental and the Sierra Madre Occidental further west.
Why is the Sierra Madre Oriental important?
This long range of tall mountains is noted for its abundant biodiversity and large number of endemic species of plants and wildlife, from the dry north to the wetter south. The Sierra Madre Oriental pine-oak forests are found at high elevations in the range (1,000–3,500 m or 3,300–11,500 ft above sea level).
How does Sierra Madre mountain range formed?
Large amounts of lava and ash were deposited on earlier surfaces in the Cenozoic Era. The Sierra Madre Oriental, composed largely of folded sedimentary rocks of the Cretaceous Period (about 145 to 65 million years ago), owes its present relief to uplift, faulting, and erosion since about 23 million years ago.
What landform lies between the Sierra Madre Occidental and the Sierra Madre Oriental?
What is happening to Sierra Madre mountains?
The Sierra Madre mountain range forest habitat is threatened by human activities. Human activities like illegal logging, mining, conversion of forest for agriculture, and migration threatened the Sierra Madre mountain range.
