What phenomenon describes the movement of water vapor into the atmosphere?

The movement of water vapor into the atmosphere is accurately described by the process of evaporation. During evaporation, liquid water from sources such as oceans, lakes, and rivers is heated by the sun, transforming into water vapor and rising into the air. This process plays a critical role in the water cycle, as it contributes to the amount of moisture present in the atmosphere, influencing weather patterns and climate.

Transpiration refers to the process by which plants release water vapor into the air through their leaves, which is a related process but specifically linked to plant activity rather than the broader context of bodies of water. Precipitation describes the phenomenon of water falling from the atmosphere back to the Earth in the form of rain, snow, sleet, or hail. Condensation is the process by which water vapor cools and changes back into liquid water, often forming clouds. Therefore, evaporation specifically captures the movement of water in its vapor state into the atmosphere.
