It also comes as the third-largest plate in terms of size. In this type of convergent boundary, a powerful collision occurs. The collision of two plates formed the Himalayan Mountains. Tectonic plates are classified into major, minor, and micro. Two locations are marked to show this type of plate boundary - the Cascade volcanoes along the Washington-Oregon coast of North America and the Andes mountain range on the western margin of South America. This plate also measures 43,600,000 sq kilometers. In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. They are also classified into; major, minor, and micro plates, according to their respective sizes. Much like oceanic-continental convergence, the subduction of one plate generates volcanism which forms a chain of volcanic islands called a volcanic island arc or simply an island arc. As it moves away from the ridge, the lithosphere becomes cooler and denser, and sediment gradually builds on top of it. When the two plates collide, a process called subduction occurs. This region below the convergence zone is called the zone of subduction. Historically, these crustal components were not studied for K isotopes because of the lack of analytical precision to differentiate terrestrial variations. As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. Lateral Movement along a Transform Plate Boundary. Let’s proceed to the activity 3, Part B. When two plates diverge, magma from the mantle wells up and cools, forming new crust; when convergence occurs, one plate descends—i.e., is subducted—below the other and crust… Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. I assume you mean tectonic plates. d. none of these. This happens due to the fact that oceanic plates are denser than continental plates. If I explore two oceanic plates at a divergent boundary, then I will observe: earthquakes ocean formation The word used to describe this term is known as “slap pull.”. Start a live quiz . where two oceanic plates are moving away from each other. What Is Lenovo Vantage? This produces an island chain. two oceanic plates collide a mid-ocean ridge enlarges a hot spot develops in the middle of an oceanic plate an oceanic plate and a continental plate converge 0 0 224; CPA Student. New questions in Biology. It is formed when a warmer material rises, cools down and then sinks. Hope this helps and if you could mark this as brainliest. At a depth of about 100 miles (160 km), materials in the subducting plate begin to approach their melting tempe… The oceanic plate is forced down into the mantle in a process known as \"subduction.\" As the oceanic plate descends, it is forced into higher temperature environments. Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust. The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Now they believe the tectonic plates move by themselves. At the convergent boundaries, these two plates meet. When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. They do not surf along. This is a list of tectonic plates on Earth's surface. Effects found at a convergent boundary between continental plates include: intense folding and faulting; a broad folded mountain range; shallow earthquake activity; shortening and thickening of the plates within the collision zone.
