Aeolian landscapes are landforms created by the action of wind, especially in arid and semi-arid regions where vegetation is sparse, rainfall is low, and loose sand or dust is abundant. Wind acts as an important geomorphic agent through the processes of erosion, transportation, and deposition. The erosional and depositional features produced by wind are characteristic of desert environments, coastal sandy areas, and other dry regions. Wind erosion mainly occurs through three processes: deflation, abrasion, and attrition. Deflation refers to the lifting and removal of loose, fine-grained particles from the ground surface. Abrasion is the process by which wind-driven sand particles wear away exposed rock surfaces. Attrition involves the collision of transported particles with one another, reducing their size and making them more rounded. One of the most common erosional features is the deflation hollow or blowout. It is a shallow to deep depression formed by the removal of loose sediments from the ground surface. Some deflation hollows may extend below the water table, resulting in the formation of desert oases. Desert pavement is another important erosional feature. As fine particles are removed by deflation, coarse gravel and pebbles are left behind, forming a closely packed, stone-covered surface that protects the underlying sediments from further erosion. Ventifacts are rocks that have been polished, grooved, or faceted by the abrasive action of wind-blown sand. Continuous abrasion gives these rocks smooth surfaces and sharp edges, often producing two or three polished faces depending on prevailing wind directions. Yardangs are elongated, streamlined ridges carved out of soft rocks by persistent wind abrasion and deflation. They are aligned
