Across
- 1. occurs where beds, or layers, of differing rock types are folded into ridges that run parallel to the coast. The outer hard rock (for example, granite) provides a protective barrier to erosion of the softer rocks (for example, clays) further inland.
- 6. Rap large boulders dumped on the beach as part as part of coastal defences.
- 7. the power of the wave is generated by the fetch. Waves erode cliffs by abrasion/corrasion and hydraulic pressure.
- 9. wearing away of cliffs by sediment flung by breaking waves.
Down
- 2. where bands of different rock type run perpendicular to the coast.
- 3. a spit joining an island to the mainland.
- 4. Development resorts such as Barton on Sea wish to build their beaches to attract tourists who are an important source of income to the area. Cliff-top hotels, however, can actually contribute to erosion, creating an impermeable zone that increases saturation in the surrounding cliff area. Tourists walking on the cliff face also contribute to erosion by destroying vegetation.
- 5. a wooden barrier built out into the sea to stop the longshore drift of sand and shingle, and so cause the beach to grow. It is used to build beaches to protect against cliff erosion and provide an important tourist amenity. However, by trapping sediment it deprives another area, down-drift, of new beach material (beach replenishment).
- 8. wall aim to prevent erosion of the coast by providing a barrier which reflects wave energy.
- 10. Replenishment the addition of new material to a beach naturally, through the action of longshore drift or artificially, through the dumping of large amounts of material.
