The Andes Mountain Range of South America is the second tallest mountain range in the world (next to the Himalayas). The Andes Mountains stretch along the Pacific coast of South America from Venezuela to Cape Horn. The Andes Mountains are volcanic in origin and are very abrupt and steep. They are part of the volcanic "Ring of Fire" that circles the Pacific Ocean. The Andes Mountains have formed due to volcanic activity along the boundary between the Pacific Plate and the South American Plate.

Volcanoes also exist in Middle America. Many of the Caribbean Islands were formed due to volcanic activity. Volcanoes exist in Mexico as well. The Popocatepetl Volcano near Mexico City is currently active. Click Here for the latest info on this volcano (optional)
