Which mechanism modifies dune shape during vegetation growth?

💡 Explanation

Vegetation reduces dune migration because wind velocity decreases near plant surfaces, which causes aeolian sediment transport reduction and deposition patterns, therefore fixing dune location, rather than weathering influenced shape under normal conditions.
