Metamorphic Rocks

• Metamorphic rocks • Morph means to change• These rocks change

under heat & pressure• Contact metamorphism

– nearby magma can change the rocks

• Regional metamorphism– Deep underground a wide

area of rocks are changed due to the heat & pressure

Metamorphic Rocks

• 2 types:– Foliated Metamorphic

Rock

• Mineral grains are arranged in plans or bands
