Name and explain the process that causes plates to move
Convection Currents:
- Heated magma rises
- Cools and creates friction
- This friction moves the plates

How are volcanoes formed?
- Where plates meet, magma can rise up between cracks in the crust
- This builds up layers over time
- Eventually a volcano is built up and formed
