Which outcome results when persistent winds encounter a surface depression under arid conditions that generate expansive loess deposits?

A)Enhanced dust plume generation
B)Glacial ice sheet formation
C)Decreased surface soil salinity
D)Increased vegetation density

💡 Explanation

Enhanced suspended particle entrainment results because deflation preferentially removes fine silt and clay; therefore, more dust is available for long-range transport rather than coarser particles creating lag deposits that armour depression surfaces.
