  • The water cycle is not complicated. Every living thing needs water, which is why the ‘water cycle’ is so important.10/17/12 2
  • Water never stops moving.Snow and rain fall to the earthfrom clouds. The rain andmelted snow run downhill intorivers and lakes, sometimescrashing over waterfalls.Eventually the water flows intothe ocean.During evaporation, the waterturns from liquid into gas, andmoves from oceans and lakesinto the atmosphere where itforms clouds. 10/17/12 3

  • Evaporation:Evaporation is when the sun heats up water in rivers or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river or ocean and goes into the air. . 10/17/12 6
  • Condensation:Water vapor in the air gets cold and changes back into liquid, making clouds.10/17/12 7
  • Precipitation: The process of precipitation is when so much water has condensed that the aircan’t hold it anymore. The clouds get heavy and water falls back down to earth in the form of rain, hail, sleet or snow. 10/17/12 8
  • Collection: When water falls back to earth like in precipitation, itmay fall back in to oceans, or rivers or it may end upon land. When it ends up on land, it will soak into the earth and become part of the “ground water” that plants and animals drink or it may run over the soil and collect in the oceans or rivers where the cycle starts all over again! 10/17/12 9
  • People use water in many different ways, we need it to survive, and if it wasn’t for the water cycle cycling through we probably wouldn’t exist. In conclusion I would like to say that we need the water cycle very very much. I would like to thank you for viewing my project!10/17/12 10
