1. Plate Tectonics & Mountain Building

2. The World’s Mountain Ranges
Himalayas
Rockies
Alps
Andes
Alpine-Himalayan Belt
Circum-Pacific Belt

3. Plate Tectonics
Structure of the Earth

4. Structure of the Earth Crust Mantle Core
Lithosphere = Crust + Upper Mantle
Lower Mantle : convection currents of magma
Asthenosphere

5. Plates and Plate margins

7. Plates movements & Plate margins
How do the plates move? 
Diverging; Converging; lateral movement
Plate margins:
Diverging/Constructive plate margin
Converging/Destructive plate margin
Conservative/Passive plate margin

8. The lithosphere and the asthenosphere

9. Constructive Plate Margin : Oceans
Oceanic Ridge
Magma thrusts up
Rifting/faulting
Two plates move apart

10. Mid-Atlantic Ridge
Indian Ridge

13.  Constructive Plate Margin: continent
Lava intrusion and extrusion
Plate movement
Displacement of rock strata under normal faulting

14. East African Rift Valley System

15. Oldoiyo Volcano, E. African Rift Valley

16.  Destructive Plate Margin
Sea Trench
Rising magma
Melting of crust
Heavier plate squeezed down
Two plates converge
Subduction

17. Sea Trenches

18.  Passive Plate Margin
San Andrea’s Fault

19. San Andrea’s Fault

20. Plate Margins
