28

Describe a divergent plate boundary

Plates are pulled away from each other
Oceanic= seafloor spreading eg. Mid Atlantic ridge
Continenetal= rift valley eg. Kenya, Africa

29

Describe a convergent plate boundary

Plates are moved towards each other
Oceanic-continenetal= composite cone/fold mountains
Oceanic-oceanic= shield volcano/tsunami
Continental-continental= fold mountains

30

Describe a conservative plate boundary

Plates rub against each other creating friction and building up pressure. The stress is suddenly released causing seismic waves from the focus. An earthquake occurs.
