Question

Consider the following statements:The amount of dust particles in the atmosphere is more in subtropical and temperate areas than in equatorial and polar regions.Subtropical and temperate areas have less dry winds.Which one of the following is correct in respect of the above statements?

The higher concentration of dust particles is found in subtropical and temperate regions due to presence of dry winds in comparison to equatorial and polar regions. Statement I is correct but Statement II is not correct.
