Across
  1. 3. faster waves move through and ahead of slower waves
  2. 7. small waves created by surface tension
  3. 8. common type of breaker
  4. 10. must occur in water deeper than 1/2 the waves length
  5. 11. vertical distance from crest to trough
  6. 12. circular path
  7. 13. pulse of energy producing waves
  8. 15. wave that do not progress
  9. 16. the distance over water that the wind blows
  10. 17. highest point of wave
  11. 18. depressed lowest below the surface
Down
  1. 1. caused by sudden movement of earth's crust
  2. 2. time required for 2 successive crest or troughs to pass a point
  3. 4. alternations of low and high water at each end
  4. 5. caused by the spread of wave energy sideways to wave travel
  5. 6. enters water with a depth of less than 1/20 of wave length
  6. 9. force that causes water to return to undisturbed level
  7. 14. region of rapid seaward flow
