Question

how is a dune different from loess

Answer 1

hi it's MAYANK
A sand dune is any hill of loose sand shaped by the wind. Sand dunes form where there is a source of sand.Active dunes constantly change shape under wind currents, but they must be free of a vegetation cover in order to form and move. They become inactive when stabilized by a vegetation cover, or when patterns of wind or sand sources change


loess :- In several large midlatitude areas of the world, the surface is covered by deposits of wind-transported silt that have settled out from dust storms over thousands of years. This material is known as loess
