Aim How do rocks change over time?

• Topic Unit 2
• Main Idea The Rock Cycle

2
1) What is the rock cycle?

• It is a series of changes that causes a rock to
  change from one form into another.

3
2) What causes the rocks to change?

• Weathering and erosion
• Heat and pressure
• Movement of crustal plates

4
3) How do we read the rock cycle chart?

• A) Arrows toward a box
• how to become that rock
• B) Arrows away from a box
• what can happen to change that rock

5
4) What process changes sediments into a
sedimentary rock?

• Deposition and burial, compaction and cementation.

6
5) How does a sedimentary rock become a
metamorphic rock?

• Heat and/or pressure (metamorphism)

7
6) How does a metamorphic rock become an igneous
rock?

• Melting into magma then solidification

8
7) What three things can happen to an igneous,
sedimentary or a metamorphic rock?

• Weathering and erosion, Heat and/or pressure and
  Melting

9
8) What can happen to sediments?

• Deposition and Burial, Compaction and Cementation
  and Erosion.

10
9) What is the only thing that can happen to
magma?

• Solidification

10) Where is metamorphic rock found?

• In between sedimentary and igneous rock.
