Rock can melt from 600- 1200C, depending on the type of rock, but this is assuming 1atm pressure. Under the earth, there are higher pressures, increasing the melting point. So although the rock should have melted by the mantle, which is 500-4000C and at a depth 35-2900km below the surface, it is a silly putty-like plastic solid rather than a liquid. The earth only becomes liquid at a depth of 2900km in the earth's outer core, but that is made of metal, not rock, so essentially, none of it.

Rock can melt at a depth of about what degree below Earth's surface?

Melted rock below earths surface?
Magma is the geological term for melted or molten rock below the earth's surface. Once the magma has reached the surface it is called lava.

When melted rock cools or hardens on it under earths surface it forms rock?
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
