Continental plate, which is denser than the oceanic mazda plate is being subducted beneath crust Events have increased our awareness of the South American plate - ( Surrounded by divergent boundaries. This depends on the The continental plate is less dense that the oceanic plate and so sinks underneath the oceanic plate. The Nazca Plate will continue to be subducted beneath the South American Plate until it is completely consumed. The Nazca Plate and the South American Plate are colliding. The oceanic mazda plate is being subducted beneath the continental south american 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. This results in frequent shallow focus earthquakes that get deeperas the ocean plate descends further, defining a zone of earthquake foci known as a Benioff zone.

The South American plate is bounded by African plate in the East, Nazca plate in the west, Arctic plate and Scotia plate in the south also Caribbean plate and North America plate in the north. Because of this, the margins of the plates are always interacting with one another. The Nazca Plate is subducting, or diving, beneath the South American Plate at a rate of about 7 centimeters (2.8 inches) per year. This is occurring as North and South America are moving westwards, widening the Atlantic . This mountain is a massive 18,942 feet tall making it the largest costalmountainin the world. As it sinks into the mantle, it becomes magma which soon rises up This magma is causing the volcanoes in the Andes Mountains to erupt. Brazil, Argentina, Bolivia, Paraguay, Peru, and Uruguay. Fractures paralleling the coast are likely related to the opening of the Atlantic Ocean as South America drifted away from Africa, starting about 130 million years ago. At the Chile Triple Junction, near the west coast of the TaitaoTres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American Plate.

The Andes Mountains were formed during a volcanic process known as the orogeny. Relative plate motions can be calculated by using global positioning system to the accuracy of 1-2mm/year. This producesmagma, which rises and maybe erupted explosively as andesite at the surface. 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. Necessary cookies are absolutely essential for the website to function properly. Is Greenland on the North American Plate? Is Point Reyes on the North American Plate or the South Pacific Plate? The Andes Mountains are the highest mountain range in the world. Surrounded by divergent boundaries. 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 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). For example, the South American Plate moves at an average rate of about 3 centimeters per year. 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.

The Nazca Plate is a geological plate in the eastern Pacific Ocean. There is a sequence composed of four periods of contrasting relative motion starting in Late Triassic that describes the relative motion of South American plate away from North American plate (Ladd, 1975). - Relatively low angle of subduction (5-15) The North American Plate is the second largest tectonic plate. 1 ). The Pacific Plate can show the chronology of the Pacific seafloor in a stair-step way, with the oldest being subducted into Asian Pacific trenches as early as 145 million years ago. The Nazca plate that lies in the eastern Pacific ocean is pulled towards the South American continent. Is the Eurasian Plate oceanic or continental? Is the Indian Plate oceanic or continental? Is the North American tectonic plate oceanic or continental? The formation of some of the youngest oceanic crusts in the world occurs as a result of a diverging plate motion. This compression is causing the Nazca Plate to buckle and fold, creating the Andes Mountains. Covers ocean-ocean and ocean-continent convergent plate boundaries, including the creation of volcanic arcs and earthquakes. Furthermore, the Nazca plate encompasses four other hotspot areas: Easter Island, Samoa, Cocos, and Juan Fernndez. 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. The Andes are a continental arc (narrow, continental volcanic chain) formed due to the volcanism above the subduction zone. The triple junction of the San Francisco and Trinidad plates is located on the Nazca plate. (Weber et al, 2001). Is the North American Plate oceanic or continental? The South American Plate is pushing eastward the Nazca Plate.
