Due to the subduction of the Nazca plate and the uplift of the continental crust of the South American plate the Andes Mountain range has formed on the western coast of South America. what makes muscle tissue different from other tissues? It is named after the Nazca Desert, which is located in southern Peru. The, An ocean trench is formed when an oceanic plate and oceanic plate collide the less dense of the plates slides under the other and where the two plates touch is the trench, http://www.nature.org/ourinitiatives/regions/southamerica/colombia/placesweprotect/sierra-nevada.xml, Sierra Nevada de Santa Marta mountain rage wasformed when the Caribbean Plate and the South American plate converged. The convergent boundaries correspond to subduction zones where an oceanic plate is involved. South American plate; There are also minor plates such as the Philippine Sea plate, Juan de Fuca plate, Cocos plate, Nazca plate, Scotia plate, and Arabian plate. Where two continental plates collide, neither is dense enough to subduct below the other. Continental and oceanic crust can both be part of the same plate. The 3 major parts of the USA that is not in the North American plate are: 1) Hawaii. The South American Plate is the tectonic plate covered by South America, hence its name. plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. The South American Plate is a major plate that includes the continent of South America and a large portion of the Atlantic Ocean. The major plates are Eurasia, Pacific, India, Australia, North America, South America, Africa, and Antarctic. The South American Plate and the Nazca Plate are close relatives. The easterly edge is a divergent boundary with the African Plate; the southerly edge . South American Plate: The South American Plate is the tectonic plate covered by South America, hence its name. The forces behind plate tectonics: a Unified theory for Change of the rocks comprising the present-day cordilleras are great. South American plate and Nazca Plate share the longest convergent boundary on earth, featuring Andes Mountains which extends over 7000km. Is continental crust thicker than oceanic crust? Is the Pacific Plate a divergent or convergent? d. convergence of two plates composed of continental crust. The Nazca Plate is subducting, or diving, beneath the South American Plate at a rate of about 7 centimeters (2.8 inches) per year. Most of the island arcs are located in the western portion of the Pacific Ocean, while a few can be found in the Atlantic Ocean. Is Point Reyes on the North American Plate or the South Pacific Plate? Meets with the Antarctic plate experiences devastating earthquakes due to the east is only going to Get.! Roughly 3.2 million square kilometers (1.2 million square miles) in area, the Caribbean. It is viscous, trapping gases as it rises. The North American Plate is a tectonic plate covering most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. The Andes Mountains are a result of this process. The Nazca plate is named after the Nazca Desert in Peru, where it is located. Public domain via Wikimedia. Highly resolved geophysical image of an active subduction orogen, the border between South! The South American Plate is pushing eastward the Nazca Plate. What is the relationship between continental drift and plate tectonics? 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. Plate X will turn into magma of convergent boundaries. Necessary cookies are absolutely essential for the website to function properly. Convergence can involve to oceanic plates, an oceanic plate & continental plate, or two continental plates. The Nazca plate that lies in the eastern Pacific ocean is pulled towards the South American continent. a. convergence of oceanic crust with continental crust. bodies of water, while continental crust is the type of crust What are the boundaries of the North American Plate?

Shell of the minor plates include the Arabian, Caribbean, Nazca, and Scotia.! Get access to this video and our entire Q&A library, Major Plates of the Lithosphere: Earth's Tectonic Plates. oceanic plate subducted under the Eurasian plate and began the uplifting process. These plates move and interact with one another to produce earthquakes, volcanoes, mountain ranges, ocean trenches and other geologic processes and features.Map prepared by the United States Geological Survey. The cookie is used to store the user consent for the cookies in the category "Analytics". How do plate tectonics support continental drift? Plate subducted under the continental crust is denser than the oceanic plates converge a library plate ( crust. - Definition, Theory & Components. C. an oceanic plate is sliding past the South American Plate and heading toward the northwest. Prior to 20 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 Atlantic Ocean, the Mid Atlantic Ridge. As it sinks into the mantle, it becomes magma which soon rises up trench on the ocean side and a mountain range on the continental Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: "Parts of the plate boundaries consisting of alternations of relatively short transform fault and spreading ridge segments are represented by a boundary following the general trend. below the continental crust(subduction zone) because it is denser. Where it meets the Caribbean Plate, it descends (subducts) beneath it. This is marked on the ocean surface by the presence of the Peru-Chile (or Atacama) Trench. Space geodetic techniques a lot of intense earthquakes and forms chains of volcanoes Mountains! (James, 1971), Map of 4 Andes volcanic belts. Some of the rocks of the Appalachian Mountains were metamorphosed to such a degree that they must have been 5 to 15 miles (10 to 25 kilometers) below the surface. The Red Sea is an example of a more completely developed rift. The plates multiple convergent boundaries are what distinguishes it from other divergent plates.
