The water in a puddle today may have floated in a cloud last week and rushed down a river last year. Water moves between air, land, and oceans through connected processes called the water cycle.
The Sun heats oceans, lakes, and rivers, turning some of the water into an invisible gas called vapor that rises into the sky. As moist air cools, some vapor turns back into tiny droplets or ice crystals that form clouds. These can grow and fall as rain or snow. Water may flow into rivers and seas, soak into the ground, or remain frozen for years.
Water takes many routes through this cycle, changing form and location. Much of it has moved through these processes many times.
