Metamorphic rocks are formed when a rock is buried deep in the earth and is subjected to extreme pressure and heat The pressure and heat causes the minerals in the rock to change into different minerals This ends up changing the rock into a completely different rock We call rocks that have been changed from one rock to another by pressure
