Transcript

  • 1. Igneous, Sedimentary, and Metamorphic Rocks Chapter 5 & 6 P Squires 2005-2006
  • 2.  
  • 3. What are igneous rocks?
    • Rocks formed from crystallization
    • of magma.
  • 4. Types of Igneous Rocks
    • Extrusive – fine grained and quickly cooled.
    • Intrusive – coarse grained and slowly cooled.
  • 5. Composed of Magma
  • 6. Magma Elements
    • Oxygen
    • Silicon
    • Aluminum
    • Iron
    • Magnesium
    • Calcium
    • Potassium
    • Sodium
  • 7.  
  • 8.  
  • 9. Bowen’s Reaction Series
    • Illustration of the relationship between cooling magma and mineral formation.
    • Feldspar – undergoes continuous change.
    • Iron-Rich Minerals – undergo abrupt change.
  • 10.  
  • 11. Layered Intrusions
  • 12. Classification of Igneous Rocks
    • Mineral Composition
    • Grain Size
    • Texture

    • Model Sediment Layering Lab

  • 16. Sedimentary
    • Sediments – pieces of solid material that have been deposited on the Earth’s surface by
        • Wind
        • Water
        • Ice
        • Gravity
        • Precipitation
  • 17. Weathering
    • Where surface is being worn away
    • Breaks rocks into smaller pieces
    • Produces clastic (broken) rocks
  • 18.  
  • 19. Erosion and Transport
    • Rocks are then transported to new locations
    • Surface material is removed (erosion)
  • 20. Deposition
    • When sediments are laid down on the ground or found in the bottom of bodies of water.
    • Some are sorted, but some are not
    • How would they be sorted?
  • 21. Deposition
  • 22. Lithification
    • Processes that transform sediments into sedimentary rocks.
    • What is cementation?
  • 23. Lithification
  • 24. Clastic sedimentary rocks
    • Coarse-Grained Clastic
    • Medium-Grained Clastic
    • Fine-Grained Clastic
  • 25. Rocks formed from Evaporation
  • 26. Metamorphic Rocks
    • When rocks don’t meet the magma stage, they become metamorphic rocks.
    • Combinations of temperature and pressure form different kinds of metamorphic rocks.
  • 27. Foliated Metamorphic Rocks
  • 28. Foliated Metamorphic Rocks Wavy layers Bands
  • 29. Non-foliated Metamorphic Rock
  • 30. Non-foliated Metamorphic Rock
  • 31. Rock Cycle
  • 32. Rock Cycle
  • 33. Rock Cycle
  • 34. Rock Cycle
  • 35. Rock Cycle
  • 36. Rock Cycle
