2.1i earth's interior and plate tectonics review and enrichment lesson

  1. 1. Review - Video Clips• Plate Tectonics http://www.youtube.com/watch?v=ryrX AGY1dmE&feature=related• Convergent Boundary http://www.youtube.com/watch?v=6OH Rb_ODo-Q&NR=1• Transform Boundary http://www.youtube.com/watch?v=1oLe KTvSIzQ&feature=related
  2. 2. Plate Tectonics• Lithosphere – the thin outer shell of Earth, consistin g of the crust and the rigid upper mantle.
  3. 3. Plate Tectonics• Athenosphere – The zone of the mantle beneath the lithosphere – consists of slowly flowing solid rock.
  4. 4. Plate Tectonics• Magma – molten rock within the earth.• Heats up materials causing it to expand
  5. 5. Plate Tectonics• Expanding region of athenosphere pushes lithosphere upwards.• This causes the lithosphere to crack and push plates apart
  6. 6. Kinds of Plate Boundaries 2 3 1 4 6 5 • Convergent Boundary
  7. 7. Kinds of Plate Boundaries 1 2 3 6 4 5 • Divergent Boundaries
  8. 8. Kinds of Plate Boundaries 1 2 Fault 3 • Transform Boundary
  9. 9. Divergent Boundaries • Divergent• Divergent Movement boundary – two plates moving apart creating a gap between.
  10. 10. Divergent Boundaries• Mid Oceanic Ridges – Mountain ranges that form at divergent boundaries
  11. 11. Divergent Boundaries• New Lithosphere is being created at mid-oceanic ridges.
  12. 12. Convergent Boundaries• Convergent boundary – two plates moving towards each other. • Convergent
  13. 13. Convergent Boundaries• Oceanic plate are thinner than Continental plate.• When they converge, one of them dives down • Convergent
  14. 14. Convergent Boundaries• Subduction – The process in which a tectonic plate dives beneath another tectonic plate and into the asthenosphere.
  15. 15. Convergent Boundaries• Oceanic crust melts when it subducts.
  16. 16. Convergent Boundaries• Old lithosphere is destroyed at convergent boundaries.
  17. 17. Transform Boundaries• Breaks in the lithosphere caused by plate movement.• Transform movement is characterized by plates scrapping past one another.
  18. 18. Transform Boundaries• Breaks in the lithosphere are caused by plate movement.• Transform movement is characterized by plates scrapping past one another.
  19. 19. Transform Boundaries• The cracks in the Earth where the rocks move past one another are called faults.• The great forces involved in plate movement tear at the Earth and cause earthquakes.
