1. Tectonic Plate Boundaries

2. Think: Plates are moving- moving away, towards, or past each other
Think: Plates are moving- moving away, towards, or past each other! What happens??

3. Plate Boundary
Place where edges of tectonic plates meet.
3 Different types of plate boundaries based on motion of the plates:

4. When two plate collide or crash into each other. 3 Possibilities:
Convergent Boundary
When two plate collide or crash into each other.
3 Possibilities:
Oceanic into Oceanic
Oceanic into Continental
Continental into Continental
 

6. Convergent Boundary
One plate must go under the other. This is called Subduction.
Subduction only occurs at convergent boundaries

7. Subduction
One tectonic plate goes under another, back into the mantle to be recycled.

8. Divergent Boundary
When two plates move away from each other
Sea floor spreading
New lithosphere is created to fill the “gap.”
 

13. Transform Boundary
Two plates slide past each other
Lithosphere is not created or destroyed
