Water cycle

  1. 1. The earth has a limited amount of water. Water keeps going around in what we call the "WATER CYCLE" This cycle is made up of a few main parts: EVAPORATION CONDENSATION PRECIPITATION INFILTRATION
  2. 2. Evaporation is when the sun heats up water in rivers, lakes or oceans and turns it into water vapor. The water vapor leaves the river, lake or ocean and goes into the air. EVAPORATION
  3. 3. CONDENSATION Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.
  4. 4. PRECIPITATION When there is too much condensed water in the air the clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.
  5. 5. Rain water soaks into the ground through the soil and the rocks. Groundwater moves very slowly. The water flows into streams and rivers and may stations in the lakes for some time. Not all the water flows back to the sea , and most evaporates before reaching the sea or an aquifer . INFILTRATION
