Question

Quizplus · Accepted Answer

Ozone is a molecule composed of three oxygen atoms, which gives it the chemical formula O3. It is not carbon dioxide (A), nor is it more healthy to breathe than oxygen (C), as it can be harmful to the respiratory system in high concentrations. Ozone is also not the most common substance in the troposphere (E), as other gases like nitrogen and oxygen make up the majority of the atmosphere. Ozone can be a pollutant in the lower atmosphere, but it is not solely caused by the burning of fossil fuels (D).
