The Water Cycle: a Drop of Water

The video explores the journey of a single drop of water, which could be thousands of years old, tracing its path from ancient seas to glaciers and clouds. It introduces the water cycle, a continuous process involving the movement of water from liquid sources to the air and back to Earth. The video highlights three key processes: evaporation, condensation, and precipitation, explaining how they contribute to the transformation of water from one form to another.
