Causes of Plate Movements

What are the three forces that cause the plates of the earth to move?

• Convection current

• Ridge push

• Slab pull

What happens when the molten material in the mantle rises and creates potential force causing the plates to move away from the ridge?

• Ridge push

• Slab pull

• Convection current

What is the force that acts when a slab, dense plate sinks and gravity pulls on the rest of the plate?
