Question

Quizplus · Accepted Answer

Ventifacts are rocks that have been shaped by abrasion from wind-blown sand or dust. The direction of the abrasion provides evidence for the direction of the prevailing wind. The side of the rock facing the dominant wind will be smoother and more polished than the other side. Therefore, ventifacts can be used to determine the dominant wind direction in an area.
