7. Plate Tectonics Pieces of Earth´s crust are in slow, constant motion
They move because of convection in the mantle

10. Plate Boundaries – 3 types

11. 1. Divergent Boundaries 2 plates are moving apart  
Ex: Mid ocean ridge, rift valley

12. 1. Divergent Boundaries 2 plates are moving apart  
Ex: Mid ocean ridge, rift valley

13. 2. Convergent Boundaries
2 plates are colliding
 
ex: Deep ocean trench (subduction), Himalayan & Andes mountains

14. 2. Convergent Boundaries
2 plates are colliding
 
ex: Deep ocean trench (subduction), Himalayan & Andes mountains

15. 3. Transform Boundaries
2 plates are sliding past each other in opposite directions
Ex. San Andreas Fault in California

16. 3. Transform Boundaries
2 plates are sliding past each other in opposite directions
Ex. San Andreas Fault in California

17. 3. Transform Boundaries
2 plates are sliding past each other in opposite directions
Ex. San Andreas Fault in California
This crack in the crust created by plates moving is called a Fault

18. 3. Transform Boundaries
2 plates are sliding past each other in opposite directions
Ex. San Andreas Fault in California
