Grade Four : Water Cycle

The Water Cycle

Evaporation

The sun heats water in oceans, lakes, and rivers. The water turns into vapor (gas) and rises into the air.

Condensation

As water vapor rises, it cools down and turns back into tiny water droplets. These droplets form clouds.

Precipitation

When clouds get heavy with water, the droplets fall back to Earth as rain, snow, sleet, or hail.

Collection

The water collects in oceans, lakes, rivers, and underground. Some of it soaks into the soil.
