Formation of Metamorphic Rocks

• Heat and Pressure deep beneath Earth’s surface can change any rock (ig, sed or met) into metamorphic rock.

• Forces inside Earth push rock down towards the heat of the Mantle.

Formation of Metamorphic Rocks

• Pockets of magma can also provide heat.

• Pressure is due to the weight of the overlying rock. (Deeper=greater pressure)
