The Earth's Fresh Water/Water Cycle

  2. 2. desalination – helps to remove dissolved salts and materials from seawater to make it usable<br />
  3. 3. water cycle - the cycle though which water moves to renew itself and return to the earth as rain<br />
  4. 4. evaporation- when water turns into a gas called water vapor. Wind and heat from the sun speed up the evaporation process.<br />
  5. 5. condensation - when water, in its gas form, called water vapor, turns back into its liquid form<br />
  6. 6. precipitation - when water in the form of ice, rain, sleet, hail, or snow, falls to Earth<br />
  7. 7. transpiration – the water that plants give off as part of their respiratory process (they “breathe” in carbon dioxide and “breathe” out oxygen – in this process, they also make water)<br />
  8. 8. runoff – when precipitation hits the ground, it is either absorbed, or it flows over the surface of the earth. This flow is called runoff.<br />
  9. 9. water vapor - water in its gas form is water vapor. If you can see it, it’s not really water vapor! <br />
  10. 10. groundwater – water that is in the ground<br />
  11. 11. water table - there are water-filled spaces underground. The top of these spaces is called the water table. Think of the top of a table to remember!<br />
  12. 12. aquifer – an underground layer of rock or soil that is filled with water. Think of it as an underground water cave.<br />
  13. 13. spring - springs are places where water seeps out of the ground. It’s where the underground water table is so high that it reaches the surface of the earth.<br />
  14. 14. well – a hole dug below the water table <br />
  15. 15. reservoir – a storage area for drinking water. It will usually look like a lake to you. Pipelines bring the water to homes and other places.<br />
