Which sediment outcome results when vegetation intercepts wind?

A)Loess deposition increases locally
B)Increased deflation of exposed bedrock
C)Dune migration accelerates downwind
D)Ventifact formation becomes more prevalent

💡 Explanation

Loess deposition increases because vegetation reduces wind velocity, causing airborne silt to drop. This process is termed aerodynamic roughness. Therefore, loess accumulates at windbreaks, rather than undergoing deflation, dune migration, or ventifact formation because those require sustained wind action.
