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.
molten rock below the surface is called magma
No. Igneous rock is formed from the solidification of magma or lava. Diamond is a mineral which is formed at great depth below the surface, from intense pressure and heat.
Lava is molten rock above the Earth's surface. Magma is molten rock below the Earth's surface.
This is described as a normal fault.

Igneous rock can form deep below the surface as intrusive igneous rock, or on or near the surface as extrusive igneous rock. X Answer is: Igneous
molten rock below the surface is called magma
No. A rock formed below earth's surface as magma is an igneous rock.
Decreasing the pressure will not produce liquid rock below the surface.
Igneous rock can form deep below the surface as intrusive igneous rock, or on or near the surface as extrusive igneous rock. X Answer is: Igneous
it is an intrusive rock
Molten rock material below the earth's surface is called magma.lava
Igneous rock formed from cooling magma below the surface is called intrusive igneous rock.
Melted rock below the eaths suface is magma
