Across
- 3. practice of designing landscapes to reduce or eliminate the need for irrigation
- 7. (river), second longest river in North America
- 10. links among ecosystem components
- 11. not permitting the passage of a fluid through the pores
- 12. freshwater stream that feeds into a larger stream or river.
- 14. structure built across a stream, a river, or an estuary to retain water
- 16. The removal, or transfer of water from one watershed to another.
- 19. water that exists underground in saturated zones beneath the surface.
- 20. flush is a moist or wet place where water reaches the earth's surface from an underground aquifer.
- 22. infectious agent is a biological agent that causes disease or illness to its host
- 23. chemicals that accidentally or deliberately enter the environment
- 25. acidity, or alkalinity of a solution
- 26. used to carry water from one location to another
- 28. underground layer of water-bearing permeable rock
- 30. gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem
- 31. prolonged period of dry weather caused by the lack of precipitation, resulting in a serious water shortage
- 33. (pollution), pollution resulting from many diffuse sources
- 34. underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock
Down
- 1. water containing less than 1,000 milligrams per liter of dissolved solids
- 2. water resource formed when the side of a hill intersects a flowing body of groundwater at or below the local water table
- 4. how much salt is in water
- 5. artificial lake where water is stored
- 6. naturally occurring solutions containing large concentrations of dissolved, inorganic ions.
- 8. a hole drilled into the ground to access water contained in an aquifer
- 9. area in which water enters an aquifer
- 13. ribbon-like body of water that flows downhill from the force of gravity.
- 15. physical material that humans need and value such as land, air, and water.
- 17. artificially apply water
- 18. used water
- 21. an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir
- 24. any relatively large body of slowly moving or standing water that occupies an inland basin
- 27. Region below the Earth's surface in which groundwater fills all the pores of material.
- 29. property of rocks that is an indication of the ability for fluids to flow through rocks
- 32. (pollution), any contaminant that enters the environment from an easily identified and confined place.
