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.
At what boundary is oceanic crust destroyed?
Oceanic crust is destroyed at convergent plate boundaries, where two tectonic plates collide. Subduction occurs at these boundaries, where the denser oceanic crust is forced beneath the less dense continental crust into the mantle, resulting in its destruction.
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust is denser and thinner than continental crust, making it more likely to be subducted beneath the less dense continental crust. This process occurs because the denser oceanic crust is pulled downward into the mantle at convergent plate boundaries due to gravitational forces. The subduction of oceanic crust beneath continental crust helps to recycle Earth's materials and plays a key role in plate tectonics and the geologic cycle.
Subduction occurs where the oceanic crust bends down towards the mantle at a?
Subduction occurs where the oceanic crust bends down towards the mantle at a subduction zone, typically at convergent plate boundaries where two tectonic plates collide. The denser oceanic plate is forced beneath the less dense continental plate, creating a deep trench and volcanic activity. This process contributes to the recycling of Earth's crust and the formation of mountain ranges and volcanic arcs.
When continental plates collide what happens to the oceanic crust between them?
When continental plates collide, the denser oceanic crust is usually subducted beneath the less dense continental crust. This process can create subduction zones, where the oceanic crust is forced downward into the mantle. The oceanic crust may melt or be recycled back into the mantle in these subduction zones.

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

SUbduction occurs where the oceanic crust bends down toward the mantle at a(an)?
deep ocean trench.
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 the process by which oceanic crust sinks beneath the trenches?
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.

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