Collisions between Earth's plats push rock down toward the heat of Earth's?

Answer 1

Plates* but I know you just made a mistake... anyway I found the answer in my science book from school.

I believe it is in the mantle because this is what it said:

The collision of continental plates produces faults, folds, and uplift of the crust. Eventually, the collision could push up a mountain range. Then, erosion begins. The mountains eventually are worn away, leading to the formation of sedimentary rock.

A collision between continental plates can also push rocks down deep into the mantle. There, heat and pressure could change the rocks to metamorphic rock. And so the rock cycle continues, for hundreds of millions of years.

(Btw i bolded the mantle part, not the book)

Answer 2

When tectonic plates collide, one plate is often forced down underneath the other in a process known as subduction. The descending plate carries rocks and sediments with it into the Earth's mantle, where they are melted due to the high temperatures, forming magma. This melted material can then rise back to the surface through volcanic activity.
