Clouds form when water vapor in the atmosphere cools to its dew point. This process involves the cooling of air that contains water vapor. As the air cools, it reaches a temperature at which it can no longer hold all the water vapor it contains, leading to condensation. The condensation results in the formation of tiny water droplets or ice crystals around particles in the air, such as dust, forming clouds.
When the air cools to the dew point, which is the temperature at which the air becomes saturated with water vapor, condensation occurs, and clouds begin to form. The dew point is crucial because it represents the point at which the air reaches 100% relative humidity, causing water vapor to condense into liquid water or ice crystals, giving rise to clouds in the sky.
