HOW IS H20 Water vapor formed?

Water vapor is formed when liquid water undergoes a process called evaporation, where heat energy causes water molecules to transition from a liquid state to a gaseous state. This can occur at any temperature when water is exposed to air, but it happens more rapidly at higher temperatures. Additionally, water vapor can also be produced through processes like transpiration from plants and combustion of fossil fuels. Once in the atmosphere, water vapor plays a crucial role in the water cycle and weather patterns.
