Which outcome results when strong winds consistently erode material from a vegetated dune's upwind side?

A)Embryo dune stabilization increases rapidly
B)Parabolic dune migration accelerates landward
C)A barchan's horn orientation stabilizes quickly
D)Longitudinal seif dune formation shifts eastward

💡 Explanation

Parabolic dune migration accelerates landward because deflation hollows form on the upwind side, reducing vegetation cover, this deflation process increases sand transport; therefore the dune moves more quickly inland, rather than stabilize or modify internal barchan features.
