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

Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
Subduction occurs where the oceanic crust bends down towards the mantle at a?
deep ocean trench.
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 happens when oceanic crust and continental crust collide?
Subduction occurs on continental boundaries because oceanic sub floor is denser and heavier than the lighter more buoyant crust. The oceanic crust slides under the continental crust areas usually on a plate boundary. This is in a recycle style mode that constantly is remaking the ocean floor. The oldest rocks on the ocean bottom are a drop in the geologic time bucket, compared to the rock ages on land.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.

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

Where did the crust on the Earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.

What is oceanic lithosphere?
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.

What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
What is the source material in basaltic magma?
Oceanic crust and oceanic sediments.
Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust
