What term describes saturated air masses that are present at higher altitudes?

The term that describes saturated air masses present at higher altitudes is clouds. When air rises, it cools and reaches a point where it can no longer hold all of its moisture, leading to condensation. This process forms tiny water droplets or ice crystals that cluster together, creating clouds.

Clouds are often associated with various weather conditions and can take on many forms based on the altitude at which they form and the atmospheric conditions surrounding them. Therefore, clouds represent the visible expression of saturated air in the atmosphere at higher altitudes, distinguishing them from other phenomena like fog (which forms near the ground), air masses (which refers to large bodies of air with uniform temperature and humidity), and dew (which is moisture that condenses near the surface, typically on cool nights).
