Across
  1. 2. formed when less resistant rocks are eroded away
  2. 4. distance the wind has travelled over seas and oceans to form waves
  3. 5. formed by the erosion of a crack due to hydraulic action
  4. 6. caused by the collapse of the roof of a cave due to erosion by the waves
  5. 9. also known as land
  6. 10. when waves strike against a rock surface trapping the air in the rock joints
  7. 12. large-scale continuous movements of water in seas and oceans

  9. 16. currents that flow parallel to the coast
  10. 18. lowest part of a wave
  11. 19. direction in which the water particles move in
Down
  1. 1. formed by the roof of an arch collapsing
  2. 2. water returns to the sea
  3. 3. this wave is also known as swells
