What may happen when dust particles are high in the atmosphere?
Answer and explanation
Correct answer: Visibility may decrease
The governing concept is light scattering by suspended particles. When dust concentration rises, the particles scatter and partly block light, producing haze and making distant objects less distinct. Consequently, visibility may decrease. High dust does not permanently stop rainfall, remove all nitrogen, or double the oxygen concentration, because none of those changes follows from ordinary dust suspension. The direct and scientifically supported effect among the options is reduced visibility.
