Water cycle powerpoint

  1. 1. The Water Cycle<br />
  2. 2. The Water Cycle consists of….<br /><ul><li>Evaporation/transpiration
  3. 3. Condensation
  4. 4. Precipitation
  5. 5. Run-off</li></li></ul><li>We reuse water everyday. It works as an endless cycle.<br />
  6. 6. The Earth is very limited in Fresh Water. We have to use and reuse what we have.<br />
  7. 7. Water can be found in 3 states.<br /><ul><li>Liquid- water, streams, lakes
  8. 8. Gas- evaporation, clouds, fog
  9. 9. Solid- ice, glaciers</li></li></ul><li><ul><li>Why do puddles disappear on hot days?
  10. 10. What is happening?
  11. 11. Water is turning from a liquid to a gas!</li></ul>Evaporation<br />
  12. 12. Transpiration<br />Similar to evaporation, only water is evaporated off of the leaves of plants after it is absorbed through the roots<br />
  13. 13. Oceans account for 80% of water that is evaporated.<br />
  14. 14. What Happens Next?<br />The process of condensation occurs<br /><ul><li>When the temp of the air is cold enough to change the water molecules from gas to a liquid
  15. 15. Water droplets form when small dust particles are present for the water to attach to</li></li></ul><li>This process forms clouds!<br />
  16. 16. The water eventually has to come down… <br />Water condenses onto tiny particles<br />Droplets collide and grow in size and weight<br />Enough collision occur to override the updraft speed<br />Droplets fall<br />
  17. 17. Precipitation<br /><ul><li>Process of when water in the atmosphere falls to the earth’s surface.</li></ul>Types of Precipitation?<br />SNOW<br />HAIL<br />SLEET<br />RAIN<br />
  18. 18.
  19. 19. Water that falls as rain and snow infiltrates into the subsurface of soil and rock. Some stays in the the soil, some may enter a stream, and some may infiltrate deeper and recharge ground aquifers.<br />
  20. 20. How do we use ground water?<br /><ul><li>Pump water out of wells
  21. 21. Create dams to channel water into aquifers
  22. 22. We depend on stored water for daily use</li></li></ul><li>Majority of water movement is contributed by the melting of snow caps<br />- Snow caps act as a natural reservoirs<br />
  23. 23. We need fresh water to survive, so use it efficiently!<br />
