Why is loess considered different from a normal sand dune?
Answer and explanation
Correct answer: Loess is a widespread deposit of fine dust
The governing concept is aeolian deposition, but loess and a sand dune differ mainly in sediment size and form. Loess consists predominantly of very fine, wind-blown silt or dust that can spread as a blanket over broad areas, whereas dunes are heaps or ridges of comparatively coarser sand. Therefore, option C is correct; the other choices describe marine salt, glacier ice, or a cave deposit, none of which defines loess.
