Which outcome occurs when sparse desert vegetation reduces surface drag?

💡 Explanation

Increased wind speed occurs close to the surface when vegetation is sparse, leading to greater sand transport via saltation. This causes faster transverse dune movement because the force equilibrium shifted toward migration, rather than dune stabilization, by vegetative anchoring.
