What phenomenon occurs during formation of cloud?

Cloud formation occurs primarily through the process of condensation, where water vapor in the atmosphere cools and transforms into tiny water droplets or ice crystals. This cooling happens when warm, moist air rises and expands, losing heat as it ascends. As the air cools, it reaches its dew point, leading to condensation around small particles called aerosols, ultimately resulting in the visible mass of clouds. Factors like temperature, humidity, and atmospheric pressure play crucial roles in this process.
