WebbWind is not as effective or "violent" an agent of erosion as are ice and water, but over time it can transport much material and finely sculpture a landscape. Wind is capable of transporting loose, unconsolidated fragments of sand and dust. Larger particles are too heavy for normal winds to move, except in storm conditions. Webb11 jan. 2024 · Once a sand dune forms, it may slowly migrate over the land. The wind moves grains of sand up the gently sloping side of the dune. This is done by saltation. When the sand grains reach the top of the dune, they slip down the steeper side. The grains are pulled by gravity. The constant movement of sand up and over the dune causes the …
