1. Types of Boundaries

2. Divergent Plate Boundary

3. New crust is generated as plates pull away from each other.
Ocean basins
Mid-Ocean Ridges
Rift Valleys
Example: Mid-Atlantic Ridge
Divergent→ Divide

6. Mid-Atlantic Ridge

8. Convergent Plate Boundary

9. Crust is destroyed as one plate dives under another plate.
This “diving” is known as subduction.
Mountains
Trenches
Volcanic Islands
Example: Nazca Plate
Converge→ Collide

15. Transform Plate Boundary

16. Example: San Andreas Fault Transform→ Slides
Crust is neither created nor destroyed as the plates slide horizontally past each other.
Earthquakes
Example: San Andreas Fault
Transform→ Slides
