The Endless Journey of Water
Original passage © Studio AM, written for Fluency.
The water in a puddle today may have floated in a cloud last week and rushed down a river last year. Water travels through the world in a repeating path 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. High up, where the air is cooler, the vapor turns back into tiny droplets that gather to form clouds. When the droplets grow heavy enough, they fall as rain or snow. That water flows back into rivers and seas, and the journey starts over.
No new water is made and none is lost; the same water has been moving in this circle for a very long time.
