Metamorphic Rocks
Metamorphic rocks are the third type we'll look at. They formed from other rocks that are changed because of heat or pressure.
Formation
Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.
Sometimes, metamorphic rocks are formed when rocks are close to some molten magma, and so get heated up.
