The Andes Mountains were formed at a convergent boundary. This occurs where two tectonic plates collide, and in the case of the Andes, it is primarily the South American Plate colliding with the Nazca Plate. The Nazca Plate is an oceanic plate that is being subducted beneath the continental South American Plate. This subduction process leads to the uplift of the Andes Mountains, as well as volcanic activity in the region.
