Structure of the earth
The Earths Plates
Giant Jigsaw Puzzle
Continental Drift
• Movement at these plates is called continental drift
• Some plates are being pulled apart (diverging)• Some are being pushed together (converging)
• But how are they being moved??
• Convection currents
Convection Current Movement
Converging and Diverging
