Question

The diagram shows the plate boundary between the Nazca Plate and the South American Plate.

The image shows the Nazca Plate, The Andes Mountains, and the South American Plate. The Andes Mountains are located along the western coast of South America.

Which is true about the Nazca Plate and the South American Plate?

Answer 1

The Nazca Plate (oceanic) is converging with and being subducted beneath the South American Plate (continental). This oceanic–continental convergence (Nazca moving eastward under South America) builds the Andes and produces earthquakes and volcanism.
