Furthermore, the Nazca plate encompasses four other hotspot areas: Easter Island, Samoa, Cocos, and Juan Fernndez. is thicker but lighter. The plate is subducting under the South American Plate at the PeruChile Trench. Convergent boundaries can also form islands. Very smooth plateaus here are remnants of landforms most likely developed under geologic and environmental conditions much different than those present today. This magma is causing the volcanoes in the Andes Mountains to erupt. The Nazca plate, an oceanic plate that shares a convergent and divergent boundary with the Simpson plate, is located in the southeastern Pacific Ocean.

Subducting is taking place beneath the west coast of South America at a rate of 8 cm per year. When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. Introduction. As one of the Earths original continents, the North American Plate started forming some three billion years ago when the planet was much hotter and mantle convection much more vigorous. This is marked on the ocean surface by the presence of the Peru-Chile (or Atacama) Trench. Peru-Chile trench is formed due to subduction of Nazca plate. The collision (or convergence) of two of these platesthe continental South American Plate and the oceanic Nazca Plategave rise to the orogenic (mountain-building) activity that produced the Andes.

In contrast, it consists of heavier and more dense materials. Every year, eight centimeters of material is subducted beneath the West Coast of South America. There is much debate over whether the South American Plate is oceanic or continental in nature. 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. At the surface, the topographic expression is commonly an oceanic Is the Somali Plate oceanic or continental?

Found inside Page 250Orogenies at OceanicContinental plate Boundaries The Andes of South America are the best example of continuing orogeny at an oceaniccontinental plate Subduction zones have a lot of intense earthquakes and volcanic eruptions. Partial melting of the subducted oceanic crust gives rise to andesitic volcanism parallel to the subduction zone. In total, half a million people were killed by such natural disasters. On what tectonic plate is most of the United States? The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the .
