If there is too much heat or pressure the rock will melt and become magma. Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing metamorphic rock. They are not made from molten rock rocks that do melt form igneous rocks instead.
