What tectonic plates make up South America? South American plate is a relatively large sized plate located below the continent, South America. crust. As subduction of the Nazca Plate continues, some of the sediments that accumulated on the ocean floor (together with some of the ocean crust) are scraped off and forced (accreted) onto the South American Plate in a process called obduction.

Both plates are capped by oceanic crust. In this lesson, you'll read about the composition and life cycle of this oceanic crust. With an area of 76 million km2, it is the Earths second largest tectonic plate, behind the Pacific Plate. 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. Are there any earthquakes on the Indo-Australian Plate? 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.

What is the relationship between continental drift and plate tectonics? Is the Pacific Plate convergent or divergent? Oceanic crust is thinner but denser, while the continental crust Andesitic magma is less dense than the surrounding material, and can have a temperature of 1000oC. Several hotspots have formed volcanic islands as a result of the movement of the Nazca Plate, which has also created seamount chains beneath South Americas surface. Partial melting of the subducted oceanic crust gives rise to andesitic volcanism parallel to the subduction zone. For example, the South American Plate moves at an average rate of about 3 centimeters per year. 2 Does North American plate consists of lithosphere?

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. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault. The new data indicates that 85% of fresh basalts and gabbros were used, and 15% of all basalts had been fully metamorphosed. The oceanic mazda plate is being subducted beneath the continental south american plate. [3] The collision of these two plates is responsible for lifting the massive Andes Mountains and for creating the numerous volcanoes (including both stratovolcanoes and shield volcanoes) that are strewn throughout them.
