Mist is a phenomenon caused by small droplets of water suspended in air. It can occur as part of natural weather or volcanic activity, and is common in cold air above warmer water, in exhaled air in the cold, and in a steam room of a sauna. The only difference between mist and fog is visibility. This phenomenon is called fog if the visibility is 1,100 yards or less. Otherwise it is known as mist. Seen from a distance, mist is bluish, and haze is more brownish.
