Water Cycle and Related Processes

The video tutorial explains the water cycle, starting with the importance of water on Earth, where 70% of the surface is covered by water. It describes the processes of evaporation and transpiration, where water turns into vapor. As vapor rises, it cools and condenses into clouds, leading to precipitation in the form of rain, hail, or snow. The water then collects in bodies of water or seeps into the ground as groundwater. This cycle is continuous, driven by the Sun's energy. The video concludes with a diagram illustrating the water cycle.
