Unit 6.2.2 Rock Cycle Test Review

1. The three basic types of rocks are -

• Igneous

• Sedimentary

• Metamorphic

• Lithospheric

2. Sedimentary rocks are formed when __________ is deposited in environments like rivers and streams.

• intrusive

• compaction

• sediment

• extrusive

3. Sedimentary rocks are changed to sediments by -

• weathering and erosion

• cementation

• heat and pressure

• compaction

4. Igneous rocks form from __________ when it cools.

• magma

• sediment

• lava

• both magma and lava

5. Limestone is a sedimentary rock. During the rock cycle, limestone is changed into marble, a metamorphic rock. The processes that act on limestone and change it into marble are -

• weathering and erosion

• heat and pressure

• compacting and cementing

• melting, cooling, and hardening

6. The process in which water, ice, wind, and gravity carries particles down and away is called -

• weathering

• cementation

• erosion

• layering

7. The process in which water, ice, wind, and gravity create newly formed sediment is called -

• erosion

• weathering

• cementation

• deposition

8. Which of the following lists the steps an igneous rock undergoes in order to become a sedimentary rock?

• deposition, erosion, melting, cooling

• weathering, erosion, deposition, cementation

• erosion, weathering, eruption, cooling

• dissolving, deposition, cooling, fracture

9. To turn a metamorphic rock into a sedimentary rock you need

• heat and pressure

• melting

• weathering & cementation

10. To turn an igneous rock into a metamorphic rock you need -

• weathering & cementation

• melting

• heat and pressure
