Understanding the Water Cycle: Sun, Evaporation, Condensation, and Precipitation

The water cycle, powered by the sun's energy, is a continuous process that includes evaporation, condensation, and precipitation. As the sun warms ocean water, it transforms from liquid to water vapor. This vapor cools, condensing into clouds. Eventually, when the clouds become heavy with water droplets, precipitation occurs in the form of rain, snow, sleet, or hail. The collected water gathers in rivers, lakes, and oceans, ready to evaporate again, restarting the cycle. Discover the fascinating ways in which water circulates in our environment.

  1. The Water (H2O) Cycle

  2. The Sun The sun’s energy is necessary to power the water cycle.

  3. Evaporation The sun warms the water in the ocean, causing it to change from water (liquid) to water vapor (gas).

  4. Condensation Once the warm gas hits the cooler air it changes back into a liquid and forms a cloud.

  5. Condensation Tiny water droplets bounce around in the cloud. As they hit each other, they stick together and become larger.

  6. Precipitation Once they become so heavy, the cloud can no longer hold them. It begins to precipitate.

  7. Precipitation can be: • Rain • Snow • Sleet • Hail

  8. Precipitation collects in: • Rivers • Lakes • Oceans Collection

  9. Then what? Right! It starts all over again! That is why it is called a cycle.

  10. The Water Cycle Sun warms ocean water causing it to EVAPORATE. Water vapor CONDENSES to form clouds. Clouds become very heavy before beginning to PRECIPITATE. Precipitation collects in rivers, lakes, and oceans – called COLLECTION. The sun warms ocean water…

  11. The Water Cycle Song • It’s raining, it’s pouring, The oceans are storing • Water from the falling rain, While thunderclouds are roaring • The rain is now stopping, The rain’s no longer dropping. • Sun comes out and soaks up water, Like a mop that’s mopping. • The water’s still there now, But hidden in the air now. • In the clouds it makes a home, Until there’s rain to share now. • It’s raining, it’s pouring. . .
