Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. The Andes are a continental arc (narrow, continental volcanic chain) formed due to the volcanism above the subduction zone. As subduction of the Nazca Plate continues, some of the sediments that accumulated on the ocean floor (together with some of the ocean crust) are scraped off and forced (accreted) onto the South American Plate in a process called obduction. Arrows along the boundary between the South American Plate and the Nazca . cocos plate and north american plate boundary type.
