The Water Cycle: Evaporation

The video explains the concept of phase change, focusing on how water transitions between solid, liquid, and gas states. It highlights evaporation as a key process where liquid water becomes vapor, occurring in various environments like lakes and skin. Transpiration in plants and respiration in animals also contribute to water vapor in the air. Additionally, boiling and geothermal activities are discussed as sources of water vapor. The video emphasizes the multiple ways water vapor enters the atmosphere.
