Which two chemicals, acted upon by sunlight, form ozone in the atmosphere?

A. Volatile organic compounds and Sulfur Dioxide.

B. Volatile organic compounds and Nitrogen Dioxide.

C. Chlorofluorocarbons and Sulfur Dioxide.

D. Chlorofluorocarbons and Nitrogen Dioxide.

A

Answer: B. Volatile organic compounds and Nitrogen Dioxide.

Ozone is made up of three oxygen atoms and is formed when sunlight and heat lead to chemical reactions between nitrogen dioxide and a volatile organic compound also known as hydrocarbons. This reaction can occur high in the atmosphere and low to the ground. As a result of the increasing amount of UV radiation emitted during the long days of summer, higher ground-level ozone occurs often. It is worthy to note that ozone is good up high and bad near the ground.
