Water cycle

  1. 1. The Water Cycle
  2. 2. The Water Cycle  Energy from the sun keeps Earth’s water moving and changing.  Water moves through living and non living parts on earth but the amount of water on Earth stays the same
  3. 3. The Water Cycle  The water cycle is the movement of water between Earth’s surface and the atmosphere.  The atmosphere is the mixture of gasses and dust that surrounds Earth.
  4. 4. The Water Cycle
  5. 5. The Water Cycle  Water moves from the oceans and land into the air and back again  The water cycle has no beginning or end, but you can describe it having four main parts.
  6. 6. Part 1  The sun’s energy warms liquid water on Earth’s surface.  Some of the liquid changes to a gas – this is called Evaporation, the change from a liquid to a gas.  Water Vapor (water in the form of a gas) now moves into the atmosphere
  7. 7. Part 1  Plants pull water from ground through roots into stems and leaves.  Plants release water vapor through tiny openings in leaves.  This is called Transpiration.
  8. 8. Part 2  As water vapor rises it cools.  When it cools enough it turns back into a liquid. This is called Condensation (change from a gas to a liquid)  The water droplets in the sky form clouds, on the ground it forms dew.
  9. 9. Part 3  Droplets in clouds combine to form bigger drops.  When drops become too heavy they fall back to Earth as Precipitation (water that falls from the atmosphere)
  10. 10. Part 3  Rain, snow, hail, and sleet are all forms of precipitation.  Rain is liquid water.  Snow, hail, and sleet are forms of solid, or frozen, water.
  11. 11. Part 4  Water falls into the oceans and on land.  Some water soaks into the soil and collects as underground water, called groundwater.
  12. 12. Part 4  Plant roots soak up groundwater.  People tap into ground water by digging wells.
  13. 13. Part 4  Some water is pulled over the surface of Earth by gravity.  This water that flows over the land surface is called runoff.  It flows into bodies of water, such as rivers, lakes, and oceans.
  14. 14. Full Circle  Then the sun’s energy warms some of it, and it evaporates again.  The cycle continues.
