The Rock Cycle

• Over the great stretch of geologic time, rocks of
  any one of the three basic types (igneous,
  sedimentary, metamorphic) may eventually be
  transformed into either of the other types.

3
Rock Cycle Part One

• Magma solidifies (turns to a solid) and forms
  igneous rock
• On Earths surface (extrusive igneous)
• Beneath surface (intrusive igneous)

4
The Rock Cycle Part Two

• Weathering and erosion occur to igneous rock and
  forms a sediment
• Sediment becomes lithified (cemented/consolidated)
  into a rock and forms sedimentary rock

5
The Rock Cycle Part Three

• Sedimentary rock becomes buried/layered.
• Increases in temperature and pressure changes
  rock to metamorphic rock
• Temperature becomes really high, turns to lava
  again and the cycle continues
