What is mined on the South American Plate? 9) According to the theory of plate tectonics: a. the asthenosphere is divided into plates. At this boundary there is a deep trench that occurs known as the Peru-Chile Trench which runs the length of this plate boundary. Off the coast of South America along the Peru-Chile trench, the oceanic Nazca Plate is pushing into and being subducted under the continental part of the South American Plate. The crust underneath the super-continent was uplifted by underlying magma moving toward the surface. This compression is causing the Nazca Plate to buckle and fold, creating the Andes Mountains. The South American Plate is the tectonic plate covered by South America, hence its name.

Today, the largest flat slab is found beneath Peru, where the oceanic Nazca Plate is being subducted under the continental South American Plate. Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. The entire region is known as a subduction zone. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape. And if you have any questions or feedback, please use the comment form below to let us know what is on your mind. The term sial refers to the composition of the upper layer of the Earths crust, It is sometimes thought to be a continental crust, despite the fact that it is absent from the vast oceanic basins, but it is a geochemical term rather than a plate tectonic one. The North and South American plates continued to move westward past the Caribbean Plate. The Andes are a continental arc (narrow, continental volcanic chain) formed due to the volcanism above the subduction zone.
