1. Plate Tectonics

2. Plate Tectonics
The theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.
CD + SFS + “plates” = Plate Tectonics!

3. Breaks in earth’s crust where rocks move
Faults
Breaks in earth’s crust where rocks move

4. Faults meet at Boundaries
3 kinds of boundaries:
Convergent
Divergent
Transform

5. Where 2 plates move apart
Divergent Boundary
Where 2 plates move apart
Mid-ocean ridge (oceanic)
Rift Valley (continental)

6. Mid-Ocean Ridge (SFS)

7. Rift Valley

8. Convergent Boundary Where 2 plates collide Oceanic-Oceanic
Oceanic-Continental
Continental-Continental
Outcome determined by DENSITY

9. Oceanic-Oceanic Convergent Boundary

10. Oceanic-Continental Convergent Boundary

11. Continental-Continental Convergent Boundary

12. Transform Boundary
2 plates slide past each other in opposite directions
