Across
  1. 5. A process where rock is worn away, broken down, or dissolved into smaller pieces by water, heat, and cold
  2. 10. A wall built parallel to the shore at the back of a beach to stop erosion and protect infrastructure like roads and houses
  3. 12. Flat areas of rock at the base of cliffs created by waves constantly crashing against the shore over time
  4. 13. A coast protected by rocks, concrete, or other materials to prevent erosion
  5. 16. An abnormal rise in sea level caused by strong winds from a storm, which can lead to coastal flooding
  6. 19. A change in the direction of a wave as it approaches land
  7. 20. A small, infrequent wave that deposits sand on the beach rather than scouring it away
  8. 21. The natural processes of weathering and deposition which shape landscapes and landforms
  9. 23. A shallow body of water separated from the open sea by a barrier such as a sandbank or coral reef
  10. 24. A narrow, high piece of land jutting out into the sea, typically formed of harder rock that resists erosion
  11. 25. Coastal trees or shrubs that grow in saline water, providing habitat and helping protect shorelines from erosion
  12. 26. A coastal area where freshwater from rivers meets and mixes with saltwater from the sea
  13. 27. The distance over water that the wind blows in a single direction; a longer fetch results in larger waves.
Down
  1. 1. Water and suspended materials, such as sand, flowing onto a beach
  2. 2. A structure built to protect the shore from erosion and reduce the impact of waves; this term is also used for sea walls or groynes
  3. 3. A narrow, sandy landform that projects from the shore into the water, often formed by wave and current action
  4. 4. Ridges of sand built up by waves and currents over time
  5. 6. A collection of waves formed by winds that can travel long distances through the ocean; it is measured from the crest to the trough
  6. 7. Water returning to the sea from the beach.
  7. 8. A large, powerful wave that constantly crashes onto the coastline, wearing away cliffs and digging out areas of beach
  8. 9. The movement of the water's surface up and down as energy (created by wind, earthquakes, or volcanoes) moves through it; wind forces the water to rise and gravity pulls it back down
  9. 11. The removal and relocation of soil or rock by water, wind, or ice.
  10. 14. A wall that extends out from a beach into the sea to trap sand moving along the shore and direct waves away to reduce erosion
  11. 15. The top of a wave where it peaks
  12. 16. Hills of sand formed over time by the wind
  13. 17. The movement of sand in a zigzag fashion along the beach until it meets an obstacle, such as a headland or a groyne
  14. 18. The bottom of a wave
  15. 22. A landform created when waves deposit a bar of sand that links an island to the coast
