The document describes the water cycle. Water evaporates from seas and forms clouds when heated by the sun. The water vapor condenses as it rises and cools in the air, forming precipitation like rain or snow. Precipitation falls back to land and seas, completing the cycle as the water returns to where it was evaporated from.
