Which phenomenon primarily encourages loess deposition at desert margins?

💡 Explanation

Reduced vegetation increases aeolian sediment trapping via surface roughness, initiating loess deposition rather than continued transport because aerodynamic drag decreases. Therefore, vegetation promotes deposition, rather than increased erosion from evaporation/salinity.
