This trench is was formed when the Nazca Plate went under the South American plate. 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. Highly resolved geophysical image of an active subduction orogen, the border between South! The western coast of South America is a very good example of an oceanic to continental convergent boundary where the Nazca plate is colliding (and being subducted beneath) the South American plate.

This trench is located in the PeruvianChile Trench, a convergent boundary subduction zone beneath the South American Plate and the Andes Mountains. Lithospheric Plates The theory of plate tectonics proposes that the lithosphere is divided into eight major plates (North American, South American, Pacific, Nazca, Eurasian, African, Antarctic, and Indian-Australian) and several smaller plates (e. g. , Arabian, Scotia, Juan de Fuca) that fit together like the pieces of a jigsaw puzzle (Fig. South American plate is bounded by African plate in the east, Nazca plate in the west, Antarctic plate and Scotia plate in the south, and Caribbean plate and North American plate in the north. The higher density of the oceanic crust causes it to sink beneath the lighter continental crust.

A product of the Nasca plate beneath the South American plate along a convergent tectonic margin, the Andes Mountains on the west coast of South America is a topographic feature that runs parallel to the Peru-Chile trench. This crustal shortening increases the vertical thickness whilst reducing the width of the lithosphere in the collision zone (imagine a car hitting a solid wall) and so produces the fold mountains of the Andes. Is The South American Plate Oceanic Or Continental There is much debate over whether the South American Plate is oceanic or continental in nature. As it descends, it drags against the overlying plate, causing both to fracture and deform.

South American plate is a relatively large sized plate located below the continent, South America. The Andes was formed by the oceanic-continental convergence The Nazca Plate is being slowly consumed as it dives deeper and deeper into the Earths mantle. Which plate is subducting beneath the South American Plate? The convergent boundaries correspond to subduction zones where an oceanic plate is involved. For example, the North American plate has continental crust (essentially the land area of North America) at its core; this is surrounded on most sides by oceanic crust. This plate is made of oceanic crust and continental . Scientists have not been able to agree on a definitive answer.

At this boundary there is a deep trench that occurs known as the Peru-Chile Trench which runs the length of this plate boundary. 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. 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. AMO warm phases occurred during 1860- 1880 and 1940-1960, and cool phases during 1905-1925 and 1970-1990. The rift split the super-continent to form a narrow ocean basin.
