Coasts Revision

3. A strong, narrow current flowing seaward from the shore through the surf zone.
6. A wave with strong swash, weak backwash and low frequency that builds beaches.
8. The type of rock, its chemical and physical characteristics.
10. A coastline where rock layers run parallel to the shore.
12. The movement of water back down the beach under gravity.
14. A tide with the smallest tidal range, occurring when the Sun and Moon are at right angles.
15. The distance over open water that the wind blows to generate waves.
16. A tide with the greatest tidal range, occurring when the Sun, Moon and Earth are aligned.
18. A high-frequency wave with strong backwash that removes beach sediment.
19. Transportation of sediment along a coast by waves approaching at an angle.

1. A coastline where rock layers run at right angles to the shore.
2. The bending of wave crests as they approach shallow water at an angle to the coastline.
4. Formed when the stress or pressure to which a rock is subjected, exceeds its internal strength (causing it to fracture).
5. The vertical difference between high tide and low tide.
7. Layers of rock.
9. These are natural breaks in the strata, caused by gaps in time during periods of rock formation.
11. A section of coastline within which sediment movement is largely self-contained.
13. The movement of water up the beach after a wave breaks.
17. Rock that does not allow water to pass through it.
