Answer 2

Sunlight and heat react with gases in the atmosphere. (option 3)

• Smog is an intense form of air pollution that causes difficulty in visibility. It is the contraction of two words- smoke and fog, because of its opacity and odour.
• There are two types of smog. Sulfurous smog is the resultant of high concentrations of sulfur compounds (oxides) in the atmosphere. These are released by fuels like coal.
• Photochemical smog is formed due to reaction of sunlight and heat with nitrogen oxides in the atmosphere. Gasoline and CFC's release these oxides.
