Wind gap is not related to wind erosion.

– A wind gap is a pass through a ridge or mountain range from which a stream that formerly occupied it has been diverted, often by stream capture. It is a feature formed by fluvial erosion and capture, not wind erosion.
– Zeugen are mushroom-shaped rock formations resulting from differential wind erosion (abrasion).
– Dreikanter are ventifacts, rocks shaped and polished by wind abrasion, typically with three facets.
– Demoiselles (also called earth pillars or hoodoos) are rock pillars with a caprock, primarily formed by differential erosion by water (rain), though wind can play a secondary role. However, wind gap is distinctly not a wind erosion landform.

Wind erosion creates distinctive landforms primarily through deflation (removal of loose particles) and abrasion (grinding of rock surfaces by wind-borne particles). Landforms like yardangs, ventifacts, deflation hollows, and sand dunes are results of wind erosion and deposition.
