The subduction of the Nazca Plate is a slow and steady process that has been occurring for millions of years. [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. The South American plate was pushed upwards as a result of the Nazca plate moving over the South American plate. South American plate is a relatively large sized plate located below the continent, South America. Some scientists believe that the Nazca Plate is divergent, while others believe it is convergent. The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge .

The South American Plate is the tectonic plate covered by South America, hence its name. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape. 3 Does the North American plate consist of continental lithosphere? The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). A number of smaller plates are used in addition to the Nazca Plate. This active convergent margin on the Aqueous Plate is the worlds longest subduction zone, stretching 7500 km (Klotz et al., 2001) and producing the largest earthquake ever recorded on Earth, the M 9.5 Valdivia earthquake. 1: North America, South America, Europe, and Africa were all part of the same super-continent.
