Across
- 2. formed when less resistant rocks are eroded away
- 4. distance the wind has travelled over seas and oceans to form waves
- 5. formed by the erosion of a crack due to hydraulic action
- 6. caused by the collapse of the roof of a cave due to erosion by the waves
- 9. also known as land
- 10. when waves strike against a rock surface trapping the air in the rock joints
- 12. large-scale continuous movements of water in seas and oceans
- 13. area that is hollowed due to wave action
- 16. currents that flow parallel to the coast
- 18. lowest part of a wave
- 19. direction in which the water particles move in
Down
- 1. formed by the roof of an arch collapsing
- 2. water returns to the sea
- 3. this wave is also known as swells
- 7. less resistant rocks
- 8. process where waves changes direction as they approach the coast
- 11. sediment size of 256mm
- 14. may form at the end of a spit
- 15. this platform is submerged during high tides
- 17. waves that build up very suddenly and rapidly break onto the beach
