Formation of Water Vapor in Evaporation

How Water Vapor Forms during Evaporation

Evaporation is a crucial stage in the water cycle. When the Sun's energy heats up bodies of water like lakes, rivers, and oceans, water molecules gain kinetic energy, which makes them move faster and eventually escape into the atmosphere as water vapor.

As the water molecules absorb the Sun's heat, they transition from a liquid state to a gaseous state, becoming water vapor. This newly formed water vapor rises into the atmosphere, where it can move from lower altitudes to higher altitudes due to temperature differences.

The warm, moist air carrying the water vapor can condense at higher altitudes, leading to the formation of clouds. Eventually, this process contributes to precipitation, completing the water cycle.
