The term for the process of water turning into vapor is evaporation. Evaporation occurs when molecules at the surface of a liquid gain enough energy to transition into the gaseous state. This energy typically comes from heat, whether from sunlight or the ambient temperature. As water is heated, molecules move more rapidly, eventually breaking free from the liquid's surface. Evaporation plays a crucial role in the water cycle, contributing to cloud formation and precipitation. It is also influenced by factors such as temperature, wind speed, and humidity. This natural process is essential for regulating climate and supporting ecosystems worldwide.
