There are four main mountain ranges that cross the country of Mexico. The mountain range that runs along the pacific coast of Mexico is the Sierra Madre Occidental.
All of them are mountain ranges that traverse Mexico from north to south. Sierra Madre Occidental is on the western side of Mexico, while the Sierra Madre Oriental is on the eastern side. Sierra Madre del Sur is lies on the South Pacific.
No. "Oriental" stands for eastern, so that mountain range is on the eastern side of Mexico.

There are three of them. The Sierra Madre Occidental runs from north to south from the Texas-Mexico border down to southern Mexico; the Sierra Madre Oriental is an extension of the Rocky Mountains, running along the Pacific Coast down to central Mexico. Finally, the Sierra Madre del Sur runs east-west along the southern portion of Mexico, on its Pacific Coast also.
Northern Mexico is dominated by the Sonoran and Chihuahuan deserts, which belong to the much greater North American Desert, which also includes the Mojave and Great Basin deserts. As for mountains, there are many of them, as Mexico is traversed by the Sierra Madre Occidental, Sierra Madre Oriental and Sierra Madre del Sur mountain ranges. Some mountains include the Pico de Orizaba, Popocatepetl, Ixtaccihuatl, Nevado de Toluca and La Malinche; all of them have more than 4,400 meters (14,500 ft) of height.
