Presentation Transcript

  1. The Rock Cycle and Tectonics One drives the other.

  2. The Rock Cycle Fig. 1.21

  3. Two tectonic episodes recorded

  4. Convergent Tectonics Horizontal compressional forces - old ocean crust destroyed - reverse dip-slip faults, folds formed - new mountains created (continental collision)

  5. Convergent Tectonics

  6. Convergent Tectonics +time +time example: Himalayan Mountains

  7. Convergent Tectonics

  8. Convergent Tectonics

  9. Divergent Tectonics Horizontal tensional forces - normal dip-slip faults - new ocean crust created

  10. Divergent Tectonics Horizontal tensional forces - normal dip-slip faults - new ocean crust created

  11. Divergent Tectonics

  12. Transform Tectonics Horizontal shearing forces - strike-slip faults - no crust created or destroyed

  13. The Rock Cycle Fig. 1.21
