What determines which plate undergoes subduction?
The oceanic plate is denser, so it undergoes subduction. This means that the oceanic plate sinks beneath the continent. This occurs at an ocean trench (Figure below). Subduction zones are where subduction takes place.
When to oceanic plates collide What is it that determines which plate Subducts?
When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.
What happens to the subducted plate?
When a tectonic plate gets subducted, it sinks underneath another tectonic plate. The crust is heated and melts as it enters the mantle and the rock…
What happens when a tectonic plate gets subducted?
Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.) At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust.
What happens to the Pacific plate when converging with the Philippine plate?
The Pacific Plate, which is thinner and denser, is subducted under the lighter Philippine Plate into the asthenosphere, where it is melted and destroyed. A subduction zone is formed. A long, narrow and deep undersea trough is formed along the subduction zone. It is an ocean trench called the Marianas Trench.
What events occur during the converging of continental plates and oceanic plates?
When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction. Subduction causes deep ocean trenches to form, such as the one along the west coast of South America.
Which plate is being subducted?
The Nazca plate is a large tectonic plate that underlies the Pacific Ocean near the western coast of South America. It is subducting under (that is, being forced under) the South American plate.
What causes the other plate to Subduct beneath the other plate during convergence?
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth’s mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle.
Which geologic feature is found at the plate boundary between the Pacific and Philippine plates?
The Philippine Sea Plate, the Amurian Plate, and the Okhotsk Plate meet near Mount Fuji in Japan. The thickened crust of the Izu–Bonin–Mariana arc colliding with Japan constitutes the Izu Collision Zone….

What was formed when oceanic plate converges with another oceanic plate?
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Whenever a subduction zone is formed, the subducted plate will end up being partially melted by the earth’s internal magma and molten.
What happens during the convergence between two continental plates?
When two continental plates converge, they smash together and create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. The Appalachian Mountains resulted from ancient convergence when Pangaea came together.
What are the different geologic features formed when continental plate and oceanic plate collides?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Usually, one of the converging plates will move beneath the other, a process known as subduction.
