1. PLATE BOUNDARIES Divergent Boundary Convergent Boundary
Transform Boundary

2. Different Types of Boundaries

3. Divergent Boundary Occurs where plates move apart
Effects – SEA FLOOR SPREADING (oceanic) and RIFT VALLEYS (continental)

4. Divergent Boundary – Arabian and African Plates
Arabian Plate
Red Sea
African Plate

5. Divergent Boundary – Iceland

6. Divergent Boundary - Oceanic

7. Divergent Boundary - Continental

8. Convergent Boundary Occurs where plates push together.
Effects – MOUNTAINS (continental) and VOLCANOES (oceanic- due to subduction)

9. Convergent Boundary – Indian and Eurasian Plates = Himalaya Mountain Range
Indian Plate

10. Convergent Boundary – Oceanic & Continental

11. Convergent Boundary – Oceanic & Oceanic
Note – plates are reversed

12. Convergent Boundaries - Continental
&

13. Transform Boundary Occurs where plates scrape past each other.
Effects – EARTHQUAKES

14. Transform Boundary – San Andreas Fault

15. HOT SPOTS

16. Hot Spots
Places where heated rock rises in plumes or thick columns from the mantle
Effects – VOLCANOES
