3 Types of Rock

• Igneous - fire
• formed by the cooling and hardening
  (solidification) of molten rock
• Sedimentary water
• formed by the deposition, burial, compaction, and
  cementation of sediments (pieces of other rocks)
• Metamorphic heated and / or squeezed
• Formed by heat and pressure on other rocks

Sedimentary Rocks

• Sedimentary form in water
• Generally formed by the deposition, burial,
  compaction, and cementation of sediments (pieces
  of other rocks)
• 3 Types
• Clastic
• Chemical (crystalline)
• Organic (Bioclastic)
