Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ozone is a secondary pollutant formed by the reaction of sunlight with nitrogen oxides and volatile organic compounds (VOCs) in the atmosphere.

Multiple choice

Which air pollutant is primarily responsible for acid rain?

  1. Sulfur dioxide

  2. Nitrogen dioxide

  3. Carbon monoxide

  4. Particulate matter
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sulfur dioxide is released into the atmosphere from the burning of fossil fuels, such as coal and oil, and is a major contributor to acid rain.
