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