Coasts

6. trapped water that is fed by streams behind a sandbar.
7. salts and acids in seawater dissolve the rock gradually over thousands of years.
10. a process of transportation that shifts eroded material along the coastline.
11. a more sheltered area usually between two headlands.
12. the water flowing towards a beach when a wave breaks.
14. a spit that connects an island to the mainland.
17. waves which remove material from the beach. The swash is weaker than the backwash.

1. an extended stretch of beach material that only joins the mainland at one end.
2. where the land meets the sea.
3. the movement of water down the beach.
4. a vertical rock face.
5. waves which help build up material on the beach. They tend to have a low frequency and strong swash.
8. waves transport material which hit the cliff and gradually wear it away.
9. the wearing away of the landscape.
13. deposits of sediment found along most coastlines.
15. action/ as waves approach the coast they trap air and force it into gaps in the cliff. This eventually weakens the rock.
16. waves cause the rocks to crash against each other, breaking them down into smaller and rounder pieces.
