Which feedback results when previously vegetated sand dunes lose their plant cover?

A)Accelerated deflation and dune migration
B)Increased soil horizon development rate
C)Enhanced chemical weathering of minerals
D)Deposition stabilization due to decreased wind

💡 Explanation

Accelerated deflation and dune migration occur because removal of vegetation reduces surface cohesion; this creates increased sediment entrainment by aeolian transportation, therefore existing dunes are eroded, rather than stabilized, by the wind.
