Water moves between pools through evaporation into water vapor, transport through the atmosphere, condensation to form clouds, and returns to the surface as precipitation. At its core, the water cycle ...

Cracked mud and salt on the valley floor in Death Valley National Park in California can become a reflective pool after rains. In a recently published paper, NASA scientists use nearly 20 years of ...

The film is a whimsical explanation of the water cycle, presented as a response to a child's letter about rain. The narrator explains how rain is formed, the process of evaporation, condensation, and ...
