Eolian erosion encompasses the abrasion of rocks by saltating sand grains and the deflation of fine materials. Of these two processes, abrasion is the easiest to identify, as it polishes and facets rocks, and commonly leaves behind characteristic features, including flutes, grooves, and pits. Wind erosion reaches its greatest extent and highest level of development in hyperarid and periglacial environments. Wind‐eroded rocks (ventifacts) also develop on beaches in temperate climates. Landforms of wind erosion develop in the zone of transportation between a sand source and a sink. They may be highly localized, such as ventifacts on a beach or hilltop, or extend over vast areas, as epitomized by the yardang systems of Africa and Asia. The orientation of flutes and grooves on ventifacts is controlled by the highest velocity winds in a region. Yardang forms represent the long‐term integration of erosion by strong wind systems.
