Description: A yardang is an aerodynamic landform that is formed through the erosion of materials, primarily sand, carried by the wind. These structures are characterized by their elongated profile and orientation, which generally aligns with the prevailing wind direction. Yardangs can vary in size, from small formations a few meters long to large structures extending for kilometers. Their surface is typically smooth and has a polished finish, resulting from the constant action of the wind that wears down rocks and sediments. This geological phenomenon is common in arid and semi-arid regions, where the lack of vegetation allows the wind to act more effectively on the terrain. Yardangs are not only interesting from a geological perspective but also provide valuable information about climatic conditions and erosion processes in a given area. Their study contributes to understanding landscape dynamics and how natural forces shape the Earth over time.
