What changes occur in rocks during metamorphism?

• Only physical changes

• Only color changes

• No changes occur

• Changes in structure, appearance, and chemical composition

What is the result of the process described as metamorphism?

• Formation of rock through compaction and cementation

• Formation of rock through heat and or pressure

• Dissolution of minerals

• Formation of rocks by melting and solidification

How much of the Earth's crust do metamorphic rocks account for?

• About 50%

• Nearly 25%

• Less than 1%

• Slightly over 5%
