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?
Explanation:
Statement I is correct: Subtropical and temperate regions, especially arid/semi-arid areas, tend to have higher dust concentrations due to dry conditions and wind erosion. Equatorial regions have high humidity and rainfall, while polar regions have less exposed land. Statement II is incorrect: Subtropical regions, particularly those under high-pressure systems, are characterized by dry, descending air and often experience dry winds, leading to deserts. Temperate regions can also experience dry winds.
