Can also be used as an up-to-date reference at Universities and Colleges across British Columbia and '' Is pulled towards the South American plate 'll read about the term lithosphere, is formed as the plate And oceanic plates converge rock, just like the ice in that glass Different boundaries. The higher density of the oceanic crust causes it to sink beneath the lighter continental crust. This diverging plate motion creates some of the youngest oceanic crusts on the planet. These recurring events have increased our awareness of the destructive power of natural hazards and the major risks associated with them. Are volcanic mountains formed at oceanic and continental convergent boundaries? Collision of continental and oceanic plates or ocean-continent convergence (formation of continental arc s and fold mountains).

Black triangles represent active volcanoes, arrows represent relative plate motion of Nazca plate with respect to South American plate, years on Nazca plate represent the oceanic plate ages, and the contoured lines represent the depth of Benioff seismic zone. 5 Which plate does most of North America sit on? This is occurring as North and South America are moving westwards, widening the Atlantic . Nazca plate has converged with South America for the past 70 million years with varying relative motion, the fastest being 100mm/year (between 49.5 to 42 million years ago, and since 26 million years ago), and at slower times 50-55mm/year. At the convergent boundaries the continental plates are pushed upward and gain thickness. Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 175. This forms an accretionary wedge (or prism), where layers of the deformed and metamorphosed sediments and ocean crust are thrust onto the South American Plate along faults or thrust planes adding to the size of the continent. collision!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Partial melting of the subducted oceanic crust gives rise to andesitic volcanism parallel to the subduction zone. Furthermore, the Nazca plate encompasses four other hotspot areas: Easter Island, Samoa, Cocos, and Juan Fernndez. Some of the minor plates include the Arabian, Caribbean, Nazca, and Scotia plates. The plates multiple convergent boundaries are what distinguishes it from other divergent plates. One trench in South America is the Peru-Chile Trench . What is more dense, oceanic or continental crust? According the theory of plate tectonics, Earth's outer shell is made up of a series of plates.The map above shows names and generalized locations of Earth's major tectonic plates. The oceanic plate being denser begins to move underneath the continental plate. The Andes Mountains are formed by the Nazca plate moving over the South American plate. At a destructive plate boundary - also known as a convergent plate boundary - the plates are moving towards one another. 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 Nazca Plate will continue to be subducted beneath the South American Plate until it is completely consumed. "[2] As a result, the eastward-moving and more dense Nazca Plate is subducting under the western edge of the South American Plate, along the continent's Pacific coast, at a rate of 77mm (3.0in) per year. The South American Plate is the tectonic plate covered by South America, hence its name. Scientists have not been able to agree on a definitive answer. Arrows along the boundary between the South American Plate and the Nazca . The molten rock, or magma, that is created as the Nazca Plate is subducted is being forced upward into the Earths crust. Does the Eurasian Plate have boundaries with the Pacific Plate? 1. At the surface, the topographic expression is commonly an oceanic The Nazca Plate is a small tectonic plate that is located off the coast of Peru. May 2001. What happens when an oceanic and continental plate collide? The Nazca plate that lies in the eastern Pacific ocean is pulled towards the South American continent. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. A convergent plate is one that moves in opposite directions and collides with another along its boundary. Mountains are from when ether two Continental plates or a Continental and oceanic plates converge. The rocks and geological layers are much older on continental plates than in the oceanic plates. (Weber et al, 2001). 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. South American plate is a relatively large .
