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.
