Question

Quizplus · Accepted Answer

The leeward side of a sand dune is the side that faces away from the wind. As sand particles are transported by the wind, they accumulate on the windward side of the dune and eventually reach a point of instability where they begin to slide down the leeward side. This results in the formation of a steep slope on the leeward side of the dune.
