Across
- 1. small cracks in the layers of rock created during earth movements.
- 4. areas of land protruding out to sea formed of resistant (harder) rock. They help protect the bay which forms between them from wave attack.
- 5. Rock: a rock that will not allow water to pass through it e.g. clay.
- 7. where a spit grows across a bay. A bar can eventually enclose the bay to create a lagoon.
- 9. an undercut part of the cliff base where wave attack concentrates erosion.
- 10. erosion caused when rocks and boulders transported by waves bump into each other and break up into smaller pieces.
- 11. a former bay cut off from the sea by a bar.
- 12. the return of water to the sea after waves break on a beach.
- 13. Action: the process by which breaking waves compress pockets of air in cracks in a cliff. The pressure may cause the crack to widen, breaking off rock.
Down
- 2. out at sea, away from the land.
- 3. Factors: see Coastal Erosion Factors and Coastal Deposition Factors.
- 6. Weathering: the breakdown of rock through the action of plants and animals.
- 8. Drift: waves approaching the coast at an angle result in the gradual zig-zag movement of beach materials along the coast.
- 10. the direction a cliff faces; facing the direction of the prevailing wind can lead to high rates of cliff erosion.
- 12. Depletion: the loss of beach material e.g. by offshore dredging of shingle banks.
