Explanation:

There are two types of smog - Classical smog and Photochemical smog. Classical smog has the following features: It is formed in the month of winter particularly under humid conditions. Thus, it occurs in cool humid conditions. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and Sulfur Dioxide.
