Step-by-step explanation:
The mountain range found along the east coast of Mexico is the Sierra Madre Oriental. It is an extension of the Rocky Mountains and spans approximately 808 miles. In contrast, the Sierra Madre Occidental is on the west coast extending from the Sierra Nevada range, spanning over 3,000 miles with peaks reaching above 9,843 feet. Mexico also features the notable Cordillera Neovolcánica range, which consists of volcanoes that stretch nearly 620 miles across the central and southern part of the country, serving as the dividing line between North and Central America with peaks soaring higher than 16,404 feet. These mountainous regions contribute to Mexico's diverse climates and natural resources, promoting tourism and providing a habitat for a wide variety of species.
