- Constructive
- where two plates are moving apart
- 1.molten rock rises from the mantle to fill the gaps between the two plate
- 2.This forms a mid ocean ridge
- As it breaks through the overlying crust it causes earthquakes
- On reaching the surface it forms volcanoes
- Plate Boundaries
- Destructive
- where two plates are moving towards one another
- When two continental plates meet there is no subduction.
- 1.When the plates meet a deep ocean trench is formed
- 2.The oceanic plate is denser so it is subducted beneath the continental plate
- 3.Oceanic plate moves downwards so it melts to create magma
- Conservative
- two plates move alongside each other
- Friction between the plates causes earthquakes
- no land is created or destroyed
- Destructive
