water cycle

The Earth’s water cycle, or hydrologic cycle,  is made up of four processes: evaporation, condensation, precipitation, and collection. When the sun heats up water on the Earth’s surface, the water turns into vapor through evaporation. The water vaporizes and cools, then turns into liquid clouds through condensation. Precipitation of snow or rain occurs when water has heavily condensed to the point that the air cannot hold it anymore. When water falls back to the ground through precipitation, it is transported to bodies of water or through soil into the ground water.
