The Trans-Mexican Volcanic Belt is a mountain range that stretches across central Mexico, running approximately 1,000 kilometers (620 miles) from west to east. This region is known for its numerous volcanoes, many of which are still active. The belt includes notable peaks such as Popocatépetl and Iztaccíhuatl, which are significant both geologically and culturally. Formed by the subduction of the Cocos Plate beneath the North American Plate, the volcanic activity in this area has created a diverse landscape. The belt is characterized by a variety of ecosystems, ranging from temperate forests to high-altitude grasslands, making it an important area for biodiversity and research.
