1. August 2008 Water Supply and Water Users Modified by Georgia Agricultural Education Curriculum Office June, 2002

2. August 2008 Water one of the most fascinating compounds on earth necessary ingredient for all living organisms

3. August 2008 Water covers about 70% of the earth of the earth’s surface 340 million cubic miles of water on the planet

4. August 2008 Water 97% is in oceans 2% is freshwater 1% is frozen in glaciers and icecaps

5. August 2008 The water cycle the amount of water on and around this planet is fairly constant availability of water is not as constant

6. August 2008 The water cycle water is continuously moving from place to place the water cycle is called the hydrologic cycle

7. August 2008 The water cycle powered by solar energy heats the water causing it to rise into the atmosphere called evaporation

8. August 2008 The water cycle water eventually returns to the ocean in the form of rain, sleet or snow returned water is called meteoric water

9. August 2008 The water cycle if the oceans were not recharged, their water level would decrease over 40 inches per year

10. August 2008 The water cycle the oceans are the largest reservoir of water we know this water is unsuitable for drinking, agricultural use, or industrial use because of the high salt content

11. August 2008 The water cycle the salt is left behind when the ocean water evaporates once the water has evaporated, it forms clouds

12. August 2008 The water cycle the water then comes back to the earth as rain, sleet or snow clouds may drop water over land or over the ocean

13. August 2008 The water cycle rainwater accounts for only 1% of the total water supply rain is vital in keeping the water balance on earth

14. August 2008 The water cycle role of plants and animals in the cycle plants absorb water through their roots and release it through tiny pores in their leaves called stomates

15. August 2008 The water cycle evaporation of water from plants is called transpiration animals also need water for their growth promotes chemical activity, regulates temperature

16. August 2008 The water cycle and transports nutrients through the blood of animals 65% of an animals weight is water

17. August 2008 The water cycle surface water about 30% of the rainfall in the US falls into out lakes, ponds and streams

18. August 2008 The water cycle this surface water is the most important element to the conservationist used by people over and over as it makes its way toward the ocean

19. August 2008 The water cycle used for agriculture industrial domestic needs

20. August 2008 Pollution renders much of the water unsuitable for our needs

21. August 2008 Ground water water that does not either evaporate or run off - soaks into the earth

22. August 2008 Three zones surface - dry soil accepts water until saturated zone of aeration - empty spaces filled with air, extends from the deepest roots to just above the water table

23. August 2008 Three zones groundwater zone - below zone of aeration water saturated rocks called aquifers can equal about 100 years of surface runoff volume

24. August 2008 Main components oceans evaporation - transpiration plants and animals surface water ground water

25. August 2008 Water users variation in population densities U.S. Population drinks about 100 million gallons of water per day only a fraction of water used

26. August 2008 Water users agriculture industry hydroelectric plants fish and wildlife recreational and domestic

27. August 2008 Agriculture main use is irrigation most common methods include: surface and sprinkler techniques

28. August 2008 Industry uses more water than any other raw material only a small part of the water is actually consumed used as a medium for other processes

29. August 2008 Industry canning - water is used to clean product and the containers cool ovens boil the product wash away wastes

30. August 2008 Industry may become part of the product most water is recycled or returned to the natural water cycle in a drainage ditch or stream

31. August 2008 Industry paper is made in water industry draws about 40 billion gallons of water per day water supply - major factor in location of industry

32. August 2008 Industry strong pollution control methods to recycle water rather than draw from an outside source

33. August 2008 Hydroelectric plants major use of water US leads the world in hydroelectric power supplies only a small portion of our needs

34. August 2008 Hydroelectric Plants concern is with damming of rivers fish runs are interrupted habitat is changed puts wildlife in danger

35. August 2008 Fish and Wildlife the way water is handled affects the fish in the water and the wildlife around the water

36. August 2008 Fish and Wildlife land wildlife, inland birds, waterfowl different species require different types of water

37. August 2008 Fish and Wildlife some fish prosper in cold mountain streams some may prefer fast running rapids

38. August 2008 Recreation boating, water skiing, fishing, sailing and swimming Swimming pools - require a lot of water to keep them in compliance with health regulations.

39. August 2008 Recreation frozen water activities ice skating, hockey, snowboarding and skiing

40. August 2008 Domestic Uses cooking baths or showers carry away wastes Each American uses more water than any other person in the world

41. August 2008 Domestic Uses In the US each person uses approximately 150 gallons of water per day bath - 3-40 gallons shower - 5 gallons per minute

42. August 2008 Domestic Uses Wash clothes - 30 gallons flush the toilet - 3 gallons water the lawn and garden, wash cars fire protection

43. August 2008 Use How wasteful can we be and still have enough clean water to survive?
