Plate Boundaries: Where 2 plates meet

• Convergent: plates collide, forms mountains

• Divergent: plates divide, forms mid ocean ridge & rift valley

• Transform boundary: plates slide, forms fault line causes earthquakes

Subduction Zone: a type of convergent boundary

• More dense plate will sink beneath the other
