Across 2. Deposits of sand and shingle found at the coast. 5. The breaking down of rocks at the Earth's surface. 7. These are often found behind a beach where sand has been blown inland and often have Marram grass growing out of them. 8. The distance of open ocean over which waves can develop. 11. A beach that develops all the way across a bay, creating a laggon behind it. 13. An isolated pillar of rock left as the roof of an arch collapses. 14. When a cliff or hillside slumps downwards along a curved surface. 16. The downward movement or sliding of material under the influence of gravity. 17. Bands of resistant rock, next to weaker rocks, that are eroded slowly and stick out to sea. 18. The type of weathering causes by plants and animals. 21. The power of the waves smashing into the cliff. Water squeezes into cracks and breaks the rock apart. 23. Waves with a strong swash and gentle backwash that build up beaches. 24. The dissolving of the soluble chemicals in rocks, usually from Limestone or Chalk.

Down 1. A gently sloping rocky platform which remain when cliffs of hard rock are eroded away. 3. A steep or vertical rock face found along many coastlines. 4. Waves that create a steep beach as breaking waves plunge downwards and the backwash pulls sand and pebbles out to sea. 6. What happens where the flow of water slows down or waves lose energy in sheltered bays. 7. A wave that rushes up the beach 9. a type of weathering resulting from water getting into cracks and turning to ice. 10. A long, narrow beach which sticks out to sea. 12. The zig-zag pattern of sediment being moved along a coast. 13. Deposits of mud that have built up in the sheltered water behind a spit. 15. Where rocks like chalk are weathered by rainwater that is made slightly acidic due to it absorbing CO2 from the air. 18. A wave that is flowing back to sea down the beach 19. When fragments of rock break away from a cliff face. 20. The 'sand papering' effect of pebbles grinding over a rocky platform, often causing it to become smooth. 22. When the sea creates a hole through a headland it is called a ...?
