2 The 3 Phases of the Water Cycle:
Precipitation Evaporation Condensation

3 Precipitation Precipitation is when water comes to the Earth from the clouds. Precipitation can come in several different forms: Rain Snow Sleet Hail

4 Evaporation Evaporation takes place when the sun’s heat warms up surface water (puddles, streams, rivers, lakes) enough to turn it from liquid form into gas. Once the water has turned into gas, or water vapor, then it rises up into the air.

5 Condensation Condensation takes place after water has evaporated into the atmosphere. Here, the water vapor cools back down and returns to its liquid form. As the water condenses, clouds are formed in the sky. When the clouds get full of water, the cycle continues to the Precipitation phase once again.
