When the surface of an object becomes colder as a result of sending its latent heat out, the existing moisture in the atmosphere contracts among itself. the air capacity for holding water depends on temp'. the warmer it is the more water vapor it can hold. during the night air temp' drops to its lowest near dawn at which point the amount of water vapor in the air may exceed its reduced capacity (this point is called the dew point) and water vapor condenses and forms dew.

(evaporation) water becomes vapor, (condensation)vapor is still vapor, (precipitation) vapor becomes water again...

The capacity becomes smaller, and the water condenses out (the source of fog).
