Question

The Andes mountains are found along the western coast of South America. What kind of plate boundary is responsible for this mountain range?

Answer 1

The answere is "The Nazca plate is converging with the South American plate."

Answer 2

The Andes mountains are an example of a CONVERGENT boundary between a continental and oceanic plate. As the plates move toward each other and intersect, once plate gets pulled underneath the other (called subduction). The result of the subduction event is part of the earth's crust being thrust upward, which produces the mountain range. Most mountain ranges are produced in this way.
