Across
- 3. an underground rock layer that serves as a reservoir of fresh water used for drinking water
- 6. zone/ the ocean floor
- 7. point source pollution/ pollution from many sources and cannot be traced back to a specific place
- 9. microorganisms that lives in extreme conditions at the bottom of the ocean
- 10. zone/ the ocean zone that contains the deep water of the ocean
- 12. zone/ the ocean zone where the water becomes a little bit deeper and extends from the intertidal zone to the edge of the continental shelf
- 13. all of the water on or surrounding the surface of Earth
- 16. the area of land where water drains from the highest to lowest point
- 19. the attraction of different types of molecules (water can stick to other surfaces)
- 20. excessive nutrients in water that cause an overgrowth of algae resulting in negative impacts on the water system
- 23. source pollution/ a single identifiable source of pollution
- 24. refers to the cloudiness of water
- 25. the process by which food is made by bacteria using a chemical energy source instead of sunlight.
- 27. aquatic animals that are able to swim and move freely
- 28. tension/ the tendency of a liquids surface to resist rupture when placed under tension or stress
- 29. a process that occurs when less-dense surface water is pushed away from the shore by wind and is replaced by cold, denser and more nutrient rich water from below
- 31. the area where the mouth of a river meets the ocean/ part freshwater and part saltwater
- 33. the attraction of the same type of molecules (water can stick to itself)
Down
- 1. a form of nitrogen found in soil, air, and water
- 2. describes the property that a water molecule has "poles" - a negative end and a positive end
- 4. heat/ the amount of heat needed to raise the temperature of a substance
- 5. microscopic animals that float or drift in the surface of the water
- 8. microscopic organisms that float or drift in the surface of the water
- 11. the amount of salt dissolved in water
- 14. oxygen/ refers to the amount of oxygen dissolved in water
- 15. basin/ the area of land drained by rivers and its branches - made up of smaller watersheds
- 17. vents/ vents at the bottom of the ocean that release very hot/ mineral rich water
- 18. involves conserving and protecting something valuable, such as the planet and its ecosystems and natural resources, including water
- 21. microscopic plants that float or drift in the surface of the water
- 22. zone/ the ocean zone where ocean meets the land
- 26. organisms in a water system that can help determine the health of the water system
- 30. the community of organisms living on the seafloor
- 32. the branch of science that studies water
