Water Cycle Concepts and Processes

The video tutorial by Sonia explains the water cycle, a continuous process involving the movement of water between Earth's oceans, atmosphere, and land. It covers the distribution of water on Earth, highlighting that 97% is saltwater and only 3% is freshwater. Key processes such as precipitation, surface runoff, infiltration, percolation, groundwater discharge, evaporation, and transpiration are discussed. The tutorial emphasizes the importance of the water cycle in sustaining life on Earth.
