5. - large boulders and rocks are rolled along the river bed.
7. - waves which help build up material on the beach, smaller backwash stronger swash.
9. - rocks carried along by the river wear down the river bed and banks.
10. - minerals are dissolved in the water and carried along in solution.
12. - fine light material is carried along in the water.
13. - the movement of water down the beach.
15. action - the force of the river against the banks can cause air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.

1. - small pebbles and stones are bounced along the river bed.
2. Weathering - Animals and plants can wear away rocks.
3. Skin - Rocks heat up and expand by day it cools and contracts it self at night
4. - waves which remove material from the beach, the swash is weaker than backwash.
6. Weathering - it is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays)
8. Thaw - When rock is exposed to weather conditions it becomes subject to processes, such as freeze-thaw weathering, that cause it to change and break down.Deposition - When a river loses energy, it will drop or deposit some of the material it is carrying.
11. - salts and acids in seawater dissolve the rock gradually over thousands of years.
12. - the water flowing towards the beach when a wave breaks.
14. - rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
15. - an area of land that sticks out from the coast, sometimes with bays either side.
