No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).

When is crust neither formed or destroyed?

Crust is neither formed nor destroyed when the rate of crust formation at mid-ocean ridges equals the rate of crust destruction at subduction zones. This balance is known as isostasy and helps maintain the overall thickness of the Earth's crust.


What is the opening in the oceanic crust?

Subduction Zone.


Is mount Cleveland a subduction zone?

Moun Cleveland formed as a result of a subduction zone, but is not a subduction zone in and of itself. A subduction zone is a feature that forms volcanoes, not a kind of volcano.


Does subduction create or destroy oceanic crust?

In a subduction zone the crust is forced inot the mantle where it is eventually melted and destroyed


Why does the oceanic crust sink beneath the continental crust at the subduction zone?

density


What is the name of the area where the crust goes back down into the earth?

The area where the crust goes back down into the Earth is called a subduction zone. Subduction zones are typically found at convergent plate boundaries where one tectonic plate is being forced beneath another plate.


What is the place where the oceanic crust is forced under the continental crust?

This is called a subduction zone.


At a destructive plate margin what determines whether a subduction zone or collision zone is formed?

The density of the tectonic plates involved determines whether a subduction zone or collision zone is formed at a destructive plate margin. If one plate is denser than the other, it will subduct beneath the other plate, forming a subduction zone. If the plates have similar densities, they will collide and form a collision zone.


What are two kinds of crust involved in a subduction zone?

Both continental and oceanic crusts are used in the process of subduction, unless you are talking about see floor spreading, then only oceanic crust is used


What are typical characteristics of subduction zone?

Where oceanic crust meets continental crust and earthquakes can occur.


What happens at a subduction convergent boundary?

The oceanic crust (the denser crust) is subducted under the lighter crust which basically means that it goes under the upper crust as they meet so they don't crash into each other like at a collision zone.


Where are the places where oceanic crust sinks back into the mantle.?

A "subduction zone".
