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

Metamorphic Rocks – Nonfoliated Metamorphic Rock Minerals grains are not arranged in planes or bands

Metamorphic Rocks Summary: – Where do metamorphic rocks form? – What is the difference between foliated and nonfoliated?

1 December 2011 OBJECTIVE: Describe the difference between foliated and nonfoliated metamorphic rock. OUTRO Which do you think would be easier to break, a foliated rock, such as slate, or a nonfoliated rock, such as quartzite? Explain.
