What effect can excess dust particles have on visibility in the atmosphere?
Answer and explanation
Correct answer: Visibility may decrease
Excess dust particles scatter and partly absorb visible light, producing haze and making distant objects appear blurred or less distinct. Therefore, option A is correct because visibility generally decreases when the concentration of airborne dust rises. Dust may sometimes act as cloud-condensation nuclei, but it does not automatically start rainfall, permanently raise air pressure, or improve clear visibility.
