What percentage of the earth's crust is metamorphic rock?
Metamorphic rocks are created from intense heat and pressure being applied to an existing rock. The existing rock is called the protolith. They can also be formed from lava being poured over the top of the earth's surface, where rocks lay underneath. Metamorphic rocks make up a large part of our earths crust. It is around 40-60% of the earts crust.

What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
