Metamorphic rocks

Metamorphic rocks need pressure and heat and two rocks to make them .



Metamorphic rocks are made with pressure, heat and two rocks. Two rocks need to be pushed together and need heat as well. The heat comes from under ground. The pressure comes from deep under ground.



I think Metamorphic rocks are good rocks because I like the shapes and sizes they come in.
