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
11
10) Where is metamorphic rock found?
In between sedimentary and igneous rock.
