Fog is nothing but cloud on the ground.It forms in the same way as a cloud forms.In short, fog comes from the condensation of water vapour near the ground.Calm wind,ground inversion and clear skies on the previous night help the formation of fog particularly in the early morning.
This is the cause of the whitish vale that we all know. The term fog is used when visibility reduces to less than 1km and the relative humidity exceeds 95%. Whereas mist is reported when visibility exceeds 1km. Obscuration by dry particles is defined as haze , which must not be mixed up with the popular, but somewhat vague term 'hazy skies' describing high thin clouds (often cirrus) obscuring the sun. Another form of fog is sea, lake or river smoke.
