Which effect occurs when wind speed decreases abruptly after saltation?

💡 Explanation

Parabolic dunes initiate where vegetation anchors parts of the dune surface; wind speed decreasing causes sand deposition. This differential sand transport shapes the dune, therefore a parabolic dune forms rather than a sheet dune because specific anchoring is present.
