Question

the photograph shows a negative consequence of air pollution. what does the photograph show? image of a forest with some dead trees and a live tree

a. pollutants react with water and are deposited on earth’s surface.

b. pollutants break down the layer of ozone in the stratosphere.

c. gaseous pollutants and particulate pollution form a haze over cities.

d. algae overgrowth occurs in the presence of too many nutrients.

Explanation:

• Option A: The image shows damaged trees, likely due to acid deposition (pollutants reacting with water, like in acid rain, deposited on Earth’s surface, harming vegetation).
• Option B: Ozone layer depletion affects UV radiation and doesn’t directly cause tree damage as shown.
• Option C: Haze over cities is an urban air pollution issue, not matching the forested scene.
• Option D: Algae overgrowth is a water pollution (eutrophication) issue, irrelevant to the forest image.

Answer:

A. Pollutants react with water and are deposited on Earth’s surface.
