What happens when the air is saturated?

When the air is saturated, it means that the air has reached its maximum capacity to hold water vapor at a specific temperature. This state of saturation occurs when the air temperature drops, leading to condensation as the excess moisture begins to form water droplets, which can contribute to cloud formation and precipitation.

At this point, any further cooling or introduction of moisture will lead to condensation, resulting in the formation of clouds or fog. Saturated air is crucial in meteorology, as it plays a central role in weather patterns, precipitation processes, and the understanding of humidity levels in the atmosphere.

The other options don’t accurately describe the state of saturated air. While changes in temperature and pressure can influence weather phenomena, they do not define saturation itself.
