Metamorphic Rocks/Rock Cycle Review

Metamorphic rocks can be separated into what two categories?

• Foliated and non-foliated
• Volcanic and plutonic
• Granite and marble
• Igneous and sedimentary

"Metamorphism" means

• Transformation of rocks due to heat, pressure, and chemical reactions
• Formation of rocks due to volcanic activity
• Breaking of rocks into smaller pieces by earthquakes
• Erosion of rocks by wind and water

Most metamorphic changes occur in what CONDITIONS?

• Low temperature and pressure conditions
• Moderate temperature and pressure conditions
• High temperature and pressure conditions
• No temperature and pressure conditions

Most metamorphic changes occur WHERE?

• Mars' surface
• Underwater
• Earth's crust
• In the atmosphere

What is contact metamorphism?

• Alteration of rocks by the heat from nearby magma
• The formation of rocks through the cooling of lava
• The process of erosion caused by wind and water
• The movement of tectonic plates

Where does contact metamorphism occur?

• On mountain peaks
• In the Earth's core
• At the bottom of the ocean
• Near the heat source, such as magma or lava, volcanic locations

What is regional metamorphism?

• Transformation of rocks due to volcanic activity
• Process of metamorphism that occurs over a large area
• Change in rock structure caused by erosion
• Process of metamorphism that occurs in a small localized area

Where does regional metamorphism occur?

• At the Earth's core
• Deeper parts of the Earth's crust, mountainous areas

• In the Earth's atmosphere
• On the surface of the Moon

Which is NOT an agent of metamorphism?

• Heat
• Pressure
• Hydrothermal Solutions

• Wind

How can heat cause metamorphism?

• By decreasing the temperature and pressure on existing rocks
• By causing rocks to expand and break apart
• By turning rocks into liquid
• By increasing the temperature and pressure on existing rocks causing chemical reactions to occur
