Across
- 1. frequency, how many waves there are in a given time limit eg one minute.
- 5. how far a wave has travelled
- 6. this is when sea water dissolves certain types of rocks.
- 8. weathering plants and animals weaken the structure of the rock until it breaks away.
- 9. sand sized particles are bounced along the sea bed by the flow of water.
- 14. large blocks of rock slide downhill
- 16. the rapid, free-fall of rock from a steep cliff face.
- 17. boulders and pebbles are rolled along the sea bed.
- 18. soil moves slowly down the slope under the influence of gravity and added weight from water creating ridges of soil
- 20. weathering If they contact rock the acid in the rainwater and seawater can dissolve it.
- 21. this is when pebbles grind along a rock platform, much like sandpaper.
- 23. the downhill movement of rock and soil because of gravity
- 24. the movement of sediment within moving water.
- 26. Slump of saturated (full of water) soil and weak rock along a curved surface
- 27. weathering One example is freeze thaw. LongShoreDrift large scale movement of sediment along a coastline in a zig zag fashion.
- 28. the breaking down of rocks in situ.
Down
- 1. the difference in height between the crest and the trough of a wave.
- 2. the sheer power of the waves as they smash against the cliff.
- 3. fine clay and sand particles are carried along within the water.
- 4. bottom of a wave
- 7. waves moving up the beach
- 10. some minerals dissolve in water.
- 11. a higher wave with a stronger backwash than swash.
- 12. the distance between two successive crests or troughs of a wave
- 13. the top of a wave
- 15. waves moving back down the beach
- 19. the wearing away of rock by moving forces (such as water)
- 22. this is when rocks that the sea is carrying knock against each other.
- 25. a low wave with a stronger swash than backwash.
