When air is cooled below its dew point, the water vapor in the air begins to condense into liquid water, forming dew or fog. This process occurs because cooler air can hold less moisture than warmer air, leading to saturation. As a result, the excess moisture is released, often visible as droplets on surfaces or as low-lying clouds. This phenomenon is crucial in weather patterns and the water cycle.

clouds
fog
The water droplets known as dew form when the air temperature passes below the "dew point" and water vapor condenses from the air onto the cooler objects. When cooled, air can no longer hold as much moisture.
When air is cooled to the dew point near the ground, it forms a stratus cloud called fog. Fog is a type of low-lying cloud that reduces visibility at the Earth's surface.
dew point
When air high above the earth' surface is cooled below the dew point it is likely to form?
When air high above the earth' surface is cooled below the dew point it is likely to form?
The water will condense forming dew.
supercooled
The temperature to which air must be cooled to reach saturation is called the dew point.
When a whole layer of air is cooled below the dew point, condensation occurs and water droplets form. This can lead to the formation of clouds or fog, depending on the altitude and humidity level.
Clouds.
If the dew point temperature is below zero, the air would need to be cooled to that temperature or below for dew to form. At that point, the water vapor in the air would condense directly into ice crystals, in a process called deposition.
Clouds.
When air high above the earth's surface is cooled below the dew point, it is likely to form clouds or fog. This occurs when the air reaches its saturation point and the water vapor in the air starts to condense into tiny water droplets or ice crystals.
It loses moisture if cooled below its dew point. It becomes more dense, and that causes it to move toward areas where the air is less dense.
