Consider the following statements : Statement I : The amount of dust particles in the atmosphere is more in subtropical and temperate areas than in equatorial and polar regions. Statement II : Subtropical and temperate areas have less dry winds. Which one of the following is correct in respect of the above statements?
A
Both Statement I and Statement II are correct and Statement II explains Statement I
B
Both Statement I and Statement II are correct but Statement II does not explain Statement I
C
Statement I is correct but Statement II is not correct
Correct answer
D
Statement I is not correct but Statement II is correct
Explanation
Statement I is correct because dust concentration is higher in subtropical and temperate regions due to vast landmasses and dry winds, whereas Statement II is incorrect because these regions are characterized by dry, descending air rather than "less dry" winds. Option (A) is the most tempting wrong choice if one assumes both statements must be true, but it fails because Statement II contradicts the factual aridity of subtropical high-pressure belts. The core concept tested is the spatial distribution of atmospheric particulates and the climatic characteristics of global pressure belts.
