What is the name of the process where ocean crust sinks back toward the mantle?

It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.


What is it called when one oceanic plate is forced beneath another plate?

Subduction.This specific process occurs at a destructive plate margin.The oceanic plate subducts at around 25-45 degrees into the mantle and the friction produced between the two plates triggers earthquakes.


Why does subduction occur at some tectonic plate boundaries?

Subduction occurs at convergent plate margins where plates are moving toward each other. Subduction occurs as old oceanic crust becomes thicker and more dense than the upper mantle directly below it. Because it is more dense, it is forced under younger, less dense oceanic crust, or under continental crust, which is always less dense. At these borders of collision, the older and more dense oceanic crust is drawn by gravity downward, into the mantle, where it is slowly melted. The two basic forces responsible are gravity and heat.


What occurs when a continental plate collides with an oceanic plate and overtakes it?

When a continental plate collides with an oceanic plate and overtakes it, this is known as subduction.


What occurs when old oceanic crust is forced back into the mantle?

It will get pushed under the crust and then it will enter something called the subduction zone the plate that slides over the old crust will create either a volcano or a mountain and the old crust will turn into a trench or anything of that source. Hope it helped

Were does subduction take place?

Subduction occurs when an oceanic plate slides under a continental plate. When the oceanic plate does this, it descends into the mantle, and the place where the subduction begins forms a deep-ocean trench.

What occurs when a continental and an ocean plate collide?

The oceanic plate goes under the continental plate and into the mantle in a process known as subduction. This results in the formation of mountains and volcanoes on the continental plate.

What are the two ways plates converge?

There are two basic types of convergent boundary. The first is a subduction zone, which occurs at a collision between two plates carry oceanic crust or one carrying continental and once carrying oceanic crust. In such a collision, one oceanic plate will subduct under the other and sink into the mantle. Such a collision produces volcanoes on the overriding plate and will produce mountain ranges on a continent. The other type of convergent boundary occurs when two continent collide. These collisions produce high mountains but not volcanoes. No subduction occurs as continental crust is not dense enough to sink into the mantle.


What is the difference between the volcanic activity that occurs at a hot spot and the volcanic activity at a subduction boundary between an oceanic plate and a continental plate?

The hot spot volcanic activity is not dependent on the subduction and melting of oceanic crust. The hot spot simply appears to be a non-moving place in the Earth's mantle where heat rises from the interior.


What is the zones places where the seafloor is forced under continents to drift?

Subduction zones are where the seafloor is forced under continental plates.
