The Water Cycle

The video explains the Earth's water cycle, highlighting its ancient and continuous nature. It covers the cycle's complexity, involving flows and storage of water in various forms and locations, such as oceans, glaciers, and aquifers. The video details precipitation, infiltration, and groundwater movement, as well as evaporation and transpiration processes. It concludes with cloud formation and the precipitation cycle, emphasizing the interconnectedness of these processes.
