Smog is derived from two words i.e. smoke and fog which is also described as the type of fog having smoke or soot particles in it or a mixture of various gases with dust and water vapour and makes breathing difficult. It is a yellowish or blackish fog mainly formed by a mixture of air pollutants like nitrogen oxides, sulphur oxides and some other organic compounds that combine with sunlight to form ozone.
