Aim: How do rocks
change over time?
Topic: Unit 2
Main Idea: The Rock Cycle
1) What is the rock cycle?
• It is a series of changes that causes a rock
to change from one form into another.
2) What causes the rocks to
change?
• Weathering and erosion
• Heat and pressure
• Movement of crustal plates
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
4) What process changes
sediments into a sedimentary rock?
• Deposition and burial, compaction and
cementation.
5) How does a sedimentary rock
become a metamorphic rock?
• Heat and/or pressure (metamorphism)
6) How does a metamorphic rock
become an igneous rock?
• Melting into magma then solidification
7) What three things can happen to
an igneous, sedimentary or a
metamorphic rock?
• Weathering and erosion, Heat and/or
pressure and Melting
8) What can happen to sediments?
• Deposition and Burial, Compaction and
Cementation and Erosion.
9) What is the only thing that can
happen to magma?
• Solidification
10) Where is metamorphic rock
found?
• In between
sedimentary
and igneous
rock.
Today’s Exit Card
• List the steps in which magma turns into a
metamorphic rock.

shale when it is changed by extreme
pressure by mountains or by extreme
heat?
