Which type of volcanism formed the Andes in South America?


convergence between two continental plates


convergence between a continental plate and an oceanic plate


production of mantle plumes


divergence between two continental plates

Answer 1

The Andes in South America were formed primarily by **convergence between a continental plate and an oceanic plate**. Specifically, the Nazca Plate, which is an oceanic plate, is subducting beneath the South American Plate, which is a continental plate. This subduction process leads to volcanic activity and the formation of the Andean mountain range.
