- 2. reef an underwater ecosystem characterized by reef-building corals
- 4. wetlands that form as rivers empty their water and sediment into another body of water
- 6. an increase in nutrient input to surface waters to the extent of overenrichment
- 8. the source of a stream or river
- 10. precipitation that does not soak into the soil but instead moves on the Earth's surface toward streams
- 13. a large, natural stream of flowing water
- 15. a body of water that flows on Earth's surface
- 16. a process in which deep, cold water rises toward the surface
- 21. water held underground in the soil or in pores and crevices in rock
- 23. a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean
- 25. any liquid or frozen water that forms in the atmosphere and falls back to the earth
- 27. a type of wetland, an area of land where water covers ground for long periods of time.
- 28. the process where water vapor becomes liquid
- 29. those organisms that live on the bottom of, on solid surfaces of, or on other substrata in aquatic and marine ecosystems
- 30. the lowering of the water table or piezometric surface caused by the extraction of groundwater by pumping a borehole
Down
- 1. Table-describes the boundary between water-saturated ground and unsaturated ground
- 3. a body of porous rock or sediment saturated with groundwater
- 5. the breeding, rearing, and harvesting of fish, shellfish, algae, and other organisms in all types of water environments
- 7. a freshwater wetland of soft, spongy ground consisting mainly of partially decayed plant matter called peat
- 9. an area of land permanently saturated, or filled, with water
- 11. occur when water pressure causes a natural flow of groundwater onto the earth's surface
- 12. the process of turning from liquid into vapor.
- 14. the downward entry of water into the soil
- 17. Currents-any current in either a liquid or a gas that is kept in motion by the force of gravity acting on differences in density
- 18. mouth The place where a river enters a lake, larger river, or the ocean
- 19. the motion of the ocean
- 20. a freshwater stream that feeds into a larger stream or river
- 22. a circular ocean current formed by Earth's wind patterns and the forces created by the rotation of the planet
- 24. lake-the remains of the bend in the river
- 26. living organisms that are able to swim and move independently of currents
