Water Cycle and Freshwater Conservation

The video tutorial explains the water cycle, highlighting key processes such as evaporation, transpiration, condensation, precipitation, and collection. It also discusses the importance of freshwater, its limited availability, and the need for water treatment to ensure safe consumption. The tutorial emphasizes the significance of using freshwater wisely.
