Evaporation: The sun heats water in rivers, lakes, and the ocean and turns it into vapor or steam, which then rises into the air. Condensation. The vapor cools and turns into tiny water droplets that attach to each other and form clouds.
Precipitation: Water falls from the clouds as rain, snow, sleet, or hail.
Run off: Some water stays on the earth’s surface and flows into rivers, lakes, reservoirs, etc.
Then the cycle begins again, as water from the earth’s surface evaporates into the air.
