Question

Quizplus · Accepted Answer

Longitudinal dunes form when opposing winds flow in similar directions, allowing the formation of two slip faces that are aligned with the wind. Parabolic dunes form when vegetation stabilizes the sand, creating a U-shaped dune with arms that curve inward. Transverse dunes form when winds blow perpendicular to the dune and sand accumulates on the windward side, creating a sharp slope on the windward side and a gentler slope on the leeward side. Barchan dunes form when winds blow in one direction, creating a crescent-shaped dune with horns pointing downwind. Star dunes form when winds blow from multiple directions, creating a complex, multi-lobed shape.
