2. Abyssal plain location in the ocean.

3. What is the vast, flat area of the ocean floor?

4. Trenches location in the ocean.

5. What is the deepest part of the ocean?

6. It is the shallow part of the ocean.

7. What is the continental margin?

8. A large flat area covered in deep sediment.

9. What is the continental rise?

10. Deep valleys cut between the continental shelf and continental slope.

11. What are submarine canyons?

12. Coarse sand containing at least 30% biogenic material.

13. What is the composition of seafloor sediment classified as ooze?

14. Sediments were originally produced by living organisms.

15. What are biogenic sediments?

16. A lump of minerals that is made of oxides and is found in scattered groups on the ocean floor.

17. What is a nodule?

18. Glacier moves across land and picks up rock. The rock becomes embedded in the ice as the glacier moves. When an iceberg break from the glacier, drifts out to sea, and melts, the rock material sinks to the ocean floor.

19. What is the process of glaciers moving inorganic sediments?

20. These are very fine silt- and clay- sized particles of rock, commonly red clay.

21. What are muds?

22. The temperature of surface water does decrease as latitude increase; that is why polar surface waters are much cooler.

23. Why are the polar waters so cold?

24. A layer in water where the temperature drops with increased depth faster than it does in other layers.

25. What is the thermocline?

26. The colder the water is, the denser it is.

27. How does density affect the temperature?

28. Where there is abundant sunlight, moderate temperatures, and low water pressure, suitable for marine life.

29. What is the neritic zone?

30. The movement of deep, cold, and nutrient-rich water to the surface.

31. What is the process of upwelling?

32. A horizontal movement of ocean water that is caused by wind and occurs at or near the ocean’s surface.

33. What is a surface current?

34. Warm equatorial currents, located in the Atlantic, Pacific, and Indian Oceans.

35. What are Equatorial Currents?

36. It is also known as the West Wind Drift.

37. What is the Antarctic Circumpolar Current?

38. The world’s densest and coldest ocean water in the world.

39. What is the Antarctic Bottom Water?

40. It is a strong current caused by an underwater landslide.

41. What are turbidity currents?

42. The time required for two consecutive wave crests to pass a given point.

43. What is a wave period?

44. The distance that wind blows across an area of the sea to generate waves.

45. What is the fetch?

46. The process by which ocean waves bend directly toward the coastline as the approach shallow water.

47. What is refraction?

48. Winds blow the crest of a wave of.

49. What are whitecaps?

50. Giant seismic ocean waves, most are caused by earthquakes, volcanic eruptions, or landslides.

51. What is a tsunami?
