Across
- 3. When sediment (Beach Material) Is moved to a new location and stays.
- 5. As sun shines on rock in the day it causes the rock to expand. During the night, it contrasts (makes the rock smaller) due to the colder temperature. Over time this continued process causes small pieces of surface to fall off.
- 6. They have a swash that is stronger than the backwash They break on the shore and deposit material, building up beaches.
- 8. when Animals and plants penetrate the weak or cracking rocks.
- 9. When beach material is moved to a new location by movement in water.
- 12. They tend to erode the coast. They have a stronger backwash than swash. They are created from big, strong waves when the wind is powerful and has been blowing for a long time.
- 15. Action The wearing away of costal rock by the impact of crashing waves against the coast.
- 16. When beaches are worn out by the water.
Down
- 1. A crack in rocks appears. Rainwater fills the rock. The rainwater freezes and expands, forcing the crack open. the ice thaws and the water goes further in the crack, the cycle continues until the rock breaks away.
- 2. When certain types of cliff erode as a result of weak acids in the sea.
- 4. The process of rocks and pebbles bumping into each other and breaking up into smoother and more rounded pieces.
- 7. Rainwater is naturally acidic because carbon dioxide from the air dissolves in it. Minerals in rock may react to the rainwater causing the rock to be weathered and worn out.
- 10. The most common wind direction.
- 11. It is the length of water over which a given wind has blown.
- 13. Any type of beach material
- 14. when the waves pick up beach material and hurl them against the base of a cliff.
