Where is the oceanic plate forced beneath another plate?

Where is the oceanic plate forced beneath another plate?

subduction zone
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. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex.

When an oceanic plate and continental plate collide which plate will be force down into the mantle?

When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the ‘subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.

What happens when one plate goes under another?

Plates Subduct When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. As the subducting plate plunges deep into the mantle, it gets so hot it melts the surrounding rock.

When one tectonic plate is forced beneath another this is called?

In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another. This process, called “subduction,” involves an older, denser tectonic plate being forced deep into the planet underneath a younger, less-dense tectonic plate.

Which feature forms when one plate is forced to bend and dive under the other 1 point?

When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.

What happens when two oceanic plates collide?

When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the ‘ subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.

Why do oceanic plates subduct under continental plates?

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The subducting plate causes melting in the mantle above the plate.

Where does the oceanic plate sink into the mantle?

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. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex.

How does a subduction zone cause an earthquake?

A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Earthquakes generated in a subduction zone can also give rise to tsunamis.
