Which surface outcome results when wind exceeds threshold?

💡 Explanation

Increased wind speed above the entrainment threshold causes accelerated dune migration and abrasion because **saltation** increases; sand grains bombard the surface. Therefore, dunes shift faster rather than stabilizing, owing to vegetative cover, or experiencing decreased saltation height or creep.
