Why can atmospheric dust be higher in some regions before the monsoon?
Answer and explanation
Correct answer: Dry surfaces and strong winds can lift particles easily
The governing concept is wind erosion under dry pre-monsoon conditions. Before regular monsoon rainfall begins, soil and other exposed surfaces may remain dry, loose, and less firmly bound. Strong winds, turbulent gusts, and convection can lift these particles into the lower atmosphere, increasing dust concentration. Rain usually removes dust by wet deposition rather than creating all of it, while oceans and ozone are not the main causes. Hence option A is correct.
