Which effect is possible when dust particles increase in the atmosphere?
Answer and explanation
Correct answer: Visibility decreases and sunlight is scattered more
Option A is correct. Dust particles are aerosols suspended in the air, and they scatter sunlight in different directions. A higher concentration can make the atmosphere hazy and reduce visibility, especially near the ground. The increase does not remove nitrogen, automatically double oxygen, or eliminate atmospheric pressure. The governing concept is the optical effect of suspended particulate matter: scattering and sometimes absorption of radiation change how clear the air appears.
