Fog is an aerosol. Aerosols are colloidal solutions in which liquids are dispersed in a gas. In case of fog, tiny particles of water are suspended in the air. These occur naturally, as well as originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels and the alteration of natural surface cover, also generate aerosols.
