Across
- 4. the gently sloping accumulation of deposits that forms at the base of the continental slope
- 8. a rhythmic movement that carries energy through space or matter
- 9. the most prominent features of the ocean basins, which run through all of the ocean basins
- 10. the lowest point of a wave
- 13. moves slowly in deep ocean waters and is caused by differences in temperature and salinity of ocean water
- 16. when high tides are higher than normal and low tides are lower than normal during a new or full moon - these moon phases cause the solar tides to enhance lunar tides
- 19. submerged sandbar located in the surf zone of most beaches
- 20. plots of water temperature against depth
- 21. the deepest parts of the ocean basins
- 22. the highest point of a wave
- 24. the flattest parts of the ocean floor
- 25. a current that flows parallel to the shore and is created by water from incoming breakers that spills over the longshore bar
- 26. the shallowest part of a continental margin extending seaward from the shore
- 27. a collapsing wave
- 28. the measure of the amount of dissolved salt in seawater
- 29. area where large rivers empty into the oceans, and where the areas of lowest salinity are often found
- 30. the level of the ocean's surfaces
Down
- 1. the upward motion of ocean water
- 2. the area where edges of continents meet the ocean
- 3. rapidly flowing water currents along the bottom of the sea
- 5. a technique that directs sound waves to the seafloor at an angle so that the sides of underwater hills and other topographic features can be mapped
- 6. submerged basaltic volcanoes that measure more than 1 km high
- 7. long ridges of sand or other sediment that are deposited or shaped by the longshore current and are separated from the mainland
- 10. the periodic rise and fall of sea level
- 11. large, extinct, basaltic volcanoes with flat, submerged tops
- 12. the sloping regions that quickly drop away from continental shelves
- 14. the area in which sediment is deposited along the shore; composed of loose sediments deposited and moved about by waves along the shoreline
- 15. wind-driven movement of ocean water that primarily affects the upper few hundred meters of the ocean
- 17. a transitional layer under the surface layer of water that is characterized by rapidly decreasing temperatures with depth
- 18. when high tides are lower than normal and low tides are higher than normal during first- or third-quarter moons - these moon phases cause solar tides to diminish lunar tides
- 23. the process in which waves advancing toward shore slow when they encounter shallower water, causing the initially straight wave crests to bend towards the headlands
