How was the Sierra Madre del Sur formed?

The Sierra Madre del Sur is a mountain range in southern Mexico. It was formed by the collision of the North American and Cocos plates. The Cocos plate is subducting beneath the North American plate, and as it does so, it is melting and rising to the surface. This magma is then erupted by volcanoes, which build up the mountains of the Sierra Madre del Sur.

The Sierra Madre del Sur is a young mountain range, and it is still growing. The volcanoes in the range are still active, and they erupt periodically. The most recent major eruption was in 1982, when the El Chichón volcano erupted. The eruption killed over 2,000 people and destroyed several villages.

The Sierra Madre del Sur is a beautiful and rugged mountain range. It is home to a variety of plants and animals, and it is a popular destination for hiking, camping, and other outdoor activities.
