  1. Teacher Information! • Necessary materials: • PowerPoint Guide

  2. TheWater Cycle Pgs159-162 in Ch. 13 of Managing Our Natural Resources Soil and Water Resources

  3. TRUE or FALSE… The amount of freshwater on our planet exceeds the amount that we use.

  4. Students will be able to… • Explain the components of the water cycle.

  5. Let’s review the WATER cycle

  6. Let’s review the WATER cycle • 70% of the earth’s surface • 340 million cubic miles of water constant amount • 97%  oceans • 2% freshwater • 1%  glaciers & icecaps • Amount available can change…

  7. The WATERCycle

  8. The WATERCycle

  9. The WATERCycle Water vapor Precipitation Transpiration Percolation Runoff Evaporation Soil water Ocean Lake Ground water

  10. The WATER Cycle • Water continuously moves from place to place • The WATER cycle = the hydrologic cycle • Powered by the • Evaporation

  11. The WATERCycle • How does water return to the earth? • Returned water  meteoric water • Transpiration  water lost from plants • Surface water  ponds, lakes, streams • 30% of rainfall • Used for agriculture, industry, domestic needs • Pollution  Much of the surface water is useless to us

  12. The WATER Cycle • Groundwatersoaks into the earth • 3 zones • Surfacewater • Aeration • Groundwater • Water table  the top of an aquifer

  13. Review • Can you explain the components of the water cycle?
