The South American plate was pushed upwards as a result of the Nazca plate moving over the South American plate. A plate capped by thin oceanic crust subducts beneath one capped by thick continental crust, forming an accretionary wedge and volcanic arc on the overriding plate. [3] The collision of these two plates is responsible for lifting the massive Andes Mountains and for creating the numerous volcanoes (including both stratovolcanoes and shield volcanoes) that are strewn throughout them.
