Across
- 2. productivity is the production of organic compounds from inorganic substances through photosynthesis or chemosynthesis
- 3. the use of light energy to convert water and carbon dioxide into energy-rich glucose molecules
- 4. tides tides that have the greatest tidal range due to the alignment of the Earth-moon-sun system.
- 11. zone beyond the continental shelf
- 14. currents vertical currents of ocean water that are caused by density differences among water masses
- 15. the movement of water from Earth's surface downward into porous rock or soil.
- 17. tidal a pattern that has a single high tide and a single low tide each tidal day
- 18. range the difference in height between successive high and low tides
- 19. trough carved in the ocean
- 20. the process by which certain microorganisms create organic molecules from inorganic nutrients using chemical energy
- 23. the accumulation of sediment found along the shore of lake or ocean
- 28. the water that hits land and does not either evaporate or infiltrate the ground
- 30. occurs when the droplet-laden clouds discharge themselves ad water falls to earth.
- 32. zone open ocean of any depth
- 33. The process by which water vapor in the atmosphere changes to its liquid state.
- 34. trough u shaped valley
- 35. zone the upper part of the ocean into which sunlight penetrates
- 38. huge circular-moving current systems that dominate the surfaces of the oceans
- 39. zone area of the surface created by the mixing of water by waves, currents, and tides
- 40. tidal a pattern that has two high tides and two low tides each tidal day
- 42. the rising of cold water from deeper layers to replace warmer surface water
- 44. level a feeding level in a food chain. Plants and algae make up the first level, followed by herbivores, and carnivores
- 46. zone is a subdivision of the benthic zone and includes the deep-ocean floor.
- 47. current a current that flows parallel to the shore and moves large amounts of sediment along the shore
Down
- 1. the layer of ocean water between about 300 meters and 1000 meters where there is a rapid change of density with depth
- 3. includes all organisms that drift with ocean currents
- 5. transpiration The roots of plants absorb water from the ground.
- 6. zone any sea-bottom surface regardless of its distance from shore and is mostly inhabited by benthos organisms
- 7. pyramid like peak
- 8. effect the deflection of currents away from their original course as a result of earth's rotation
- 9. includes all animals capable of moving independently of the ocean currents, by swimming or other means of propulsion
- 10. regular changes in the elevation of the ocean surface
- 12. cover vegetation can slow the movement of runoff, so there is more time for
- 13. steep sided depression, bowl
- 16. a thick mass of ice originating on land as a result of the compaction and recrystallization of snow.
- 19. web a group of interrelated food chains
- 21. tides tides that have the lowest tidal range, occurring near the times of the first-quarter phases of the moon
- 22. is the total amount of solid material dissolved in water
- 24. valley smaller valley above the main trough
- 25. zone the part of the ocean in which there is sufficient light to support photosynthesis
- 26. zone area where land and ocean meet and overlap
- 27. The process by which liquid water changes to water vapor and enters the atmosphere as gas. Bodies of water Vast surface areas of oceans, rivers, lakes and other bodies of water.
- 29. chain a sequence of organisms through which energy is transferred, starting with the primary producer
- 31. zone seaward from the low-tide line
- 36. currents masses of ocean water that flow from one place to another
- 37. the distance that the wind has traveled across open water
- 41. organisms living organisms living on or in the ocean bottom
- 43. refraction is the bending of waves, and it affects the distribution of energy along the shore
- 45. currents movements of water that flow horizontally in the upper part of the ocean's surface
