• Sedimentary rock is formed when layers of this
  become cemented together.

22
c-1 40

Heat and pressure
C-2 20

• Metamorphic rocks can be igneous or sedimentary
  rock that is changed by this.

28
Foliated rocks
C-2 40

• This type of metamorphic rock forms when heat and
  pressure have flattened the minerals into bands.

29

33
Rock Cycle
C-2 20

• One type of rock being changed into another is
  part of this cycle.

34
Melting then cooling
C-2 40
