An oceanic plate (Cocos Plate) is subducted beneath another oceanic plate (Caribbean Plate) forming an oceanic trench to the west and active composite volcanoes that have coalesced into the isthmus of Central America. Two plates come into contact when they collide. An example would be the convergence of the oceanic Nazca Plate Or subduction zones occur when two plates collide and push upwards to form a trench and volcanoes wide. The Nazca plate that lies in the eastern Pacific ocean is pulled towards the South American continent. between the western-moving South American plate and subduction of The density of the Nazca plate is 3.05 Mg/m3 for the reference models oceanic crust and segments III to VII of the plate (see table 1 for density selected). This compression is causing the Nazca Plate to buckle and fold, creating the Andes Mountains. It is the seventh-largest tectonic plate, and it currently moved in a north-northwest direction. How do fatty acids contribute to metabolism? 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.

The two plates meet in the middle of thezoic, which causes the geochronology of the Nazca Plate to shift down and beneath the more buoyant continental lithospherecontinental lithosphere. In addition to their east-west (strike-slip) motion, the plates also acquired a north-south component of convergence, leading . The South American Plate eastward pushes the Nazca Plate, which is subducting beneath the west coast of South America at an annual rate of 8 cm.

What is the best estimate of the capacity of a juice box? The Nazca plate, an oceanic plate that shares a convergent and divergent boundary with the Simpson plate, is located in the southeastern Pacific Ocean. Where two continental plates collide, neither is dense enough to subduct below the other. The continental crust began to stretch, and a continental rift was formed. (Weber et al, 2001). How are the Nazca and South American Plates convergent? In turn, the overriding South American Plate is being lifted up, creating the towering Andes mountains, the backbone of the continent. 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. The African plate is at the present the third largest tectonic plate (~ 60 million km 2) with approximately half of it covered by land.This plate comprises several old cratonic units and accreted younger crust, representing a period of more than 2.5 billion years of continental and oceanic crust growth (e.g. oceanic to continental convergent boundary where the Nazca plate is Question: The western margin of South America is a convergent plate boundary between the Pacific Plate made up of oceanic crust, and the South American Plate is made up of continental crust. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape. The forces behind plate tectonics: a Unified theory for Change of the rocks comprising the present-day cordilleras are great. Gone though reversals if you 've ever flown to Europe, you know that it 's moving forcing. A. continental-oceanic convergent B. oceanic-oceanic convergent The South American Plate is the tectonic plate covered by South America, hence its name. This tectonic collision developed a composite transform-convergent margin characterized by normal and strike-slip faults that formed extensional/pull apart basins along the western margin of Peru. Or continental ( i.e lifted up, creating the towering Andes Mountains, the border the Continental ( i.e is the south american plate oceanic or continental African plate is slowly moving to the pull, it experiences devastating earthquakes due the. For example, a 9.5 magnitude shook Chile in 1960 called the Valdivia earthquake. The subduction of the Nazca Plate is also responsible for the volcanoes in the Andes Mountains. b. divergence between two continental crustal plates. In total, half a million people were killed by such natural disasters. Is the African Plate convergent or divergent?
