Geography Question in UPSC Prelims 2025 on Dust Particle in Atmosphere.
Q. Consider the following statements:
Statement I: The amount of dust particles in the atmosphere is higher 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?
✅ Correct Answer: C. Statement I is correct, but Statement II is not correct
Explanation:
Statement I: ✅ Correct- Dust particle concentration is higher in subtropical and temperate regions due to factors like arid conditions and strong winds that pick up dust. These regions often experience less precipitation and more sunshine, further contributing to the presence of dust.
Statement II: ❌ Incorrect – Subtropical and temperate areas experience more dry winds, not fewer. Dry winds are a key factor in driving the high concentration of dust particles in these regions. They transport dust from arid areas to other regions.
