What happens to this crust as it is pushed down into the mantle?

As it is cold and wet, it continues to sink and slowly heats up. This causes partial melting and it acts as a source of magma for volcanoes that form above it.
so does other people burn when the go into mantle?

Where is old crust pushed down into a trench?
subdution zone
Oceanic plates are pushed down into the upper mantle in?
subduction zones
How far is the mantle away from the crust of the earth?
A distance of about 1,800 miles [2,896.8 kilometers] separates the earth's mantle from the earth's crust.
Is the upper mantle part of the lithosphere or asthenosphere?
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
Why are each of the earth's plates floating like a raft?
The crustal plates are less dense than the mantle but hard and solid. Because of heat convection currents in the plastic-like rock of the mantle, the crust is pushed and pulled as material from the mantle pushes it's way to the surface and is drawn down again, creating tectonic plate movement.
What happens when a plate of oceanic crust collides with a plate of Continetal crust why?
the oceanic crust slides down and burns in the mantle and forms a volcano
What happens at oceanic-oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
What happens at an oceanic- oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
Is the crust also the lithosphere?
Not exactly. The lithosphere is the crust and the top of the mantle (down to the asthenosphere).
When rocks are pushed down into the mantle and melt it become?
magma
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
