Which atmospheric condition would likely encourage cloud growth?

Cloud growth is most effectively facilitated by rapid vertical air movement. When air rises quickly, it expands and cools due to the decrease in atmospheric pressure at higher altitudes. As the air cools, it can reach its dew point more rapidly, which is the temperature at which water vapor condenses into tiny water droplets, forming clouds. This process generates significant upward motion and creates an environment conducive to the development of clouds.

High atmospheric pressure typically results in stable weather conditions and clear skies, discouraging cloud formation. Low humidity indicates that there is less moisture present in the air, making it difficult for clouds to form, as insufficient water vapor means there is less potential for condensation. A stable temperature gradient suggests that air parcels are unlikely to rise significantly, which would also hinder cloud development since clouds generally form when air ascends and cools.
