The Incredible Water Cycle

Have you ever wondered where rain comes from? It is all part of the

water cycle, the continuous movement of water on Earth. Evaporation happens when

the Sun's heat changes liquid water into water vapor. Condensation occurs as water vapor cools

and forms clouds in the sky. During precipitation, water falls back to Earth as

rain, snow, or hail. In collection, water gathers in

rivers, lakes, and oceans to start again. The water cycle

is a continuous process that supports life on Earth.
