coast gateway 1

2. arrangement and composition of rock found in an area
4. the process by which the weight of water compresses air trapped in rock joints; this pressure weakens and shatters rocks over time
7. a steep and near-vertical rock face found along coasts
8. large scale and ontinuous movements of water in the seas and oceans
10. the process by which sediments are hurled against the coast,scraping coastal rocks and eroding the coast
12. a coastal environment that is constantly changing due to various factors
16. the area where the land meets the sea
17. water that moves up the beach
18. the distance the wind has travelled over seas and oceans to form waves
19. develop when energy from wind blowing across seas and oceans is transferred to the water surface
20. the process by which sea water reacts chemically with water-soluble minerals in coastal rocks and dissolve the rocks

1. a gently sloping platform at the base of a cliff
3. ocean currents that flow parallel to a coast
5. the process by which rock particles carried by waves rub or hit against one another and break down into smaller pieces
6. the daily alternate rise and fall in the sea level
9. the process by which waves change direction as they approach a coast
11. water that moves back to the sea from the beach
13. waves with a strong swash and a weak backwash resulting in sediments being eroded from the beach
14. combined effect of longshore current and beach drift
15. the interaction of plant and animal communities with each other and the environment
