Water Cycle

The video explains the ancient origins of Earth's water and its continuous cycle through evaporation, condensation, precipitation, and collection. Oceans play a crucial role in this cycle by replenishing fresh water sources. Evaporation occurs when water turns into vapor, while condensation forms clouds. Precipitation returns water to Earth as rain, hail, or snow. Finally, collection gathers water in bodies like rivers and oceans, restarting the cycle.
