Multiple choice

How does industrialization contribute to air pollution?

  1. It releases greenhouse gases into the atmosphere.

  2. It emits particulate matter and toxic chemicals.

  3. It increases the concentration of ozone in the troposphere.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Industrialization contributes to air pollution by releasing greenhouse gases, particulate matter, and toxic chemicals into the atmosphere. These pollutants can cause respiratory problems, heart disease, and other health issues.
