Coasts Geography

2. When a spit grows across a bay
4. Erosion caused when rocks bump into each other and break up into smaller pieces
7. a type of coastal defence with rocks in cages
10. the collapse of the cliff due to freeze-thaw weathering
11. formed due to hard rock eroding more slowly than soft rock
13. The movement of eroded material.
14. Occurs when material being transported by the sea is dropped due to the sea losing energy.
16. The wearing away and removal of material by a moving force, such as a breaking wave.
18. An isolated pillar of rock left when the top of an arch has collapsed.
20. Large boulders dumped on the beach as part of the coastal defences.

1. a ridge of sand formed by the wind
3. The zigzag movement of sediment along a shore
5. a depositional landform formed when a beach sticks out to sea.
6. A rocky, level shelf at or around sea level representing the base of old, retreated cliffs.
8. The wearing away of cliffs by sediment flung by breaking waves.
9. A wooden barrier built out into the sea to stop the longshore drift of sand and shingle, and so cause the beach to grow.
12. The downhill movement of weathered material under the force of gravity.
15. A concrete wall which prevents erosion by providing a barrier which reflects wave energy.
17. the collapse of the cliff due to prolonged rain
19. A wave-eroded passage through a small headland formed by a cave being eroded through
21. A large hole in the cliff caused by waves forcing their way into cracks in the cliff face.
