Slate metamorphic if put under more. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Each kind of igneous rocks contains different minerals and has different structures. 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.

Igneous sedimentary and metamorphic. Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened. Metamorphic rocks are formed by the changes ageing occuring in either sedimentary or igneous rocks.
