·      Fog is made up of droplets of water suspended in the lower layers of atmosphere resulting from the condensation of water vapour around nuclei of floating dust or smoke particles

·      Smog also called smoke fog, is a form of fog that occurs in areas where the air contains a large amount of smoke

·      Mist is the term given for a reduction of visibility between 1-2km caused by the condensation, producing water droplets within the lower layers of atmosphere. It is the intermediate between fog and haze.

·      Mist and fog are identical and are formed in the same way. The only difference is that in a fog, the particles of water are smaller and visibility is poorer than in a mist.

·      Haze is formed by water particles that have condensed around the nuclei in the atmosphere but may also be a result of particles of smoke, dust or salt in the air
