Transcript

  • 1. Ch 10 Plate Tectonics
    • Section 10.3 Theory of Plate Tectonics
  • 2. Ah – ha!
    • Scientists realized that the continental drift idea could be explained by sea floor spreading……(early 1960’s)
    • The Earth’s crust is broken into “plates” that move, grow, and subduct.
  • 3. Page 280
  • 4.
    • Plates are made of ______ and upper ________; these compose the _________.
    • These ______ plates float and move atop the plasticlike layer called the ________.
  • 5.
    • Plates are made of crust and upper mantle ; these compose the lithosphere .
    • These rigid plates float and move atop the plasticlike layer called the asthenosphere .
  • 6.  
  • 7. The Earth’s Plates
  • 8. Global Plate Motions
  • 9.  
  • 10. Types of Boundaries
    • Convergent
    • Divergent
    • Transform
  • 11. Tectonics – study of formation of crustal features
    • Oceanic crust – thin, dense, basaltic
    • Continental crust – thick, less dense, granitic
  • 12. Convergent Boundary
    • Ocean plate – continental plate
  • 13. Convergent Boundary
    • ocean plate – ocean plate
  • 14.  
  • 15. Convergent Boundary
    • Continental plate – continental plate
  • 16.  
  • 17. Himalayan Mountains
  • 18. Divergent Boundary Common at Mid-Ocean Ridges (M-O-R)
  • 19.  
  • 20.  
  • 21. East African Rift Valley – Red Sea
  • 22. Transform Boundary
  • 23.  
  • 24. What makes the plates move?
  • 25. Plates move like they are groceries on a conveyor belt
  • 26. What Drives It: Convection
  • 27. Examples of convection
  • 28. Examples of convection
  • 29. Plate Tectonics
    • Features on Earth’s surface are a result of interactions of plates at their boundaries
      • Earthquakes
      • Faulted and folded mountains
      • Volcanic landforms
      • Rocks
  • 30.  
  • 31.
    • No
    • Plates are destroyed as fast as they are created (2 ways)
    • Plates may be subducted and melted or may push be pushed upward to form mountains
    So is the Earth getting bigger?
