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
- D.Statement I is incorrect but Statement II is correct
▶ Answer & Explanation
Correct answer: C. Statement I is correct but Statement II is not correct
Subtropical and temperate regions are characterized by semi-arid and arid conditions, leading to increased dust and particulate matter due to wind erosion and the prevalence of dry winds. Equatorial regions, with high rainfall and vegetation, tend to wash out particles, while polar regions have limited terrestrial sources of dust. Therefore, Statement I is correct as dust is generally more prevalent in subtropical and temperate zones. Statement II is incorrect because these regions often experience significant dry winds which contribute to dust transport.
