The Water Cycle

Have you ever wondered where rain comes from? Or why puddles disappear on a sunny day? The answer lies in one of Earth's most fascinating systems.

The water cycle, also known as the hydrological cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water changes states between liquid, vapor, and ice as it moves through this cycle.

About 97% of Earth's water is in the oceans. Only 3% is fresh water, and most of that is locked in ice caps and glaciers.

Key Processes

  1. Evaporation: Water transforms from liquid to vapor
  2. Condensation: Water vapor cools and forms clouds
  3. Precipitation: Water falls as rain, snow, sleet, or hail
  4. Collection: Water gathers in rivers, lakes, and oceans
