Metamorphic Rock

Metamorphic Rock

Vocabulary Review

• Metamorphism: process by which any kind of rock is changed into metamorphic rock

• Regional Metamorphism: occurs in large areas around plate boundaries

• Contact Metamorphism: occurs when magma rises through Earth's crust and touches existing rock

• Foliated: layers or bands that you can see

• Nonfoliated: do not have visible bands or layers

Multiple Choice

Metamorphic rocks form from ___.

• igneous rocks
• other metamorphic rocks
• sedimentary rocks
• all types of rocks

Multiple Choice

Multiple Choice

What are the two main types of metamorphic rocks and how are they different?
