  2. It reduces the pH of rainwater.

  3. It alters the chemical composition of clouds.

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

Air pollution contributes to acid rain by increasing the concentration of sulfur dioxide and nitrogen oxides in the atmosphere, reducing the pH of rainwater, and altering the chemical composition of clouds.

Multiple choice
