  • 1. Types of Rocks Sedimentary, Igneous, Metamorphic
  • 2. Sedimentary Rocks
    • Made up of smaller rocks cemented together
    • Sometimes have fossils
    • Usually have layers.
  • 3. Sedimentary Rocks
    • Form when loose sediment (rocks, sand) is deposited by water, compacted, and cemented together.
    • Form as a chemical reaction in the water that leaves a chemical deposit, usually on an ocean bottom.
    • Form along beaches, by rivers, or under the water in lake or oceans.
  • 4. Sedimentary Rocks
  • 5. Examples of Sedimentary Rocks
  • 6. Igneous Rocks
    • Some were once liquid magma that erupted from volcanoes. They cooled very quickly. (Extrusive)
    • Others were once liquid magma, but they did not erupt from volcanoes. Instead, they cooled slowly underground. (Intrusive)
  • 7. Igneous Rocks
    • Extrusive:
      • Rocks that are from cooled lava (above ground.
      • They cooled very quickly, therefore formed small crystals
    • Intrusive
      • Rocks that are from cooled magma (below ground)
      • They cooled very slowly, therefore formed large crystals.
  • 8. Igneous Rocks
    • Which is extrusive and which is intrusive?
    Extrusive Intrusive
  • 9. Igneous Rocks
  • 10. Examples of Igneous Rock
  • 11. Metamorphic
    • Form when igneous, sedimentary, or other metamorphic rocks are heated and/or squished, forming a new rock type.
    • Usually has interlocking crystals and layers (called foliation)
  • 12. Metamorphic
    • This can either happen underground or above ground.
      • Underground: high pressure and heat
      • Above ground: volcano erupting
    • When classifying metamorphic rocks, they always come from a parent rock.
  • 13. Metamorphic Rocks
  • 14. Examples of Metamorphic Rocks

  • 16. Review
    • What are the three rock types?
    • What are sedimentary rocks?
    • What are igneous rocks?
    • What are the two types of igneous rocks?
    • What are metamorphic rocks?
