B. Why do plates move?
Watch the video here
– Plates move due to the convection currents in the mantle.
– Convection currents are the cycle of heating, rising, cooling
and sinking.

11. D. Different types of Crust
LO: Why is the earths crust so unstable?
CONTINENTAL OCEANIC
- 25-100km thick
- Light (and so floats)
-Older (over 1500m yrs)
- Not destroyed as
easily as oceanic crust
- 5-10KM thick
- Dense (and so sinks)
- Newer
- Constantly being
renewed and destroyed
