1. Deflation - wind entrains particles with a diameter of less than 60 micrometres.
2. Abrasion - entrained sediment is thrown against rock surfaces. ("wind-scouring").
Hope this helps.
The polishing of rocks by wind blown particles is known as abrasion, where small particles carried by the wind erode the rock surface. Pitting occurs when these particles strike the rock surface, causing small depressions or dents in the rock. Over time, both processes can lead to the smoothing and shaping of rocks in areas with high wind exposure.
The primary destructive forces that erode mountains include weathering (physical and chemical breakdown of rock), erosion (transportation of rock particles by water, ice, or wind), and mass wasting (downslope movement of rock and soil). These processes gradually wear down mountain peaks and reshape the landscape over time.
Wind can contribute to weathering by carrying abrasive particles (like sand) that can wear away rock surfaces through abrasion. Wind can also transport fine particles that erode softer rocks through a process called deflation. Additionally, winds can enhance chemical weathering by bringing in moisture or gases that react with rock surfaces.
Soil will erode the fastest, as it is made up of loose particles that can easily be moved by wind or water. Sand is also relatively easily eroded, but rocks are more resistant to erosion due to their harder composition.
The passage of pure air itself won't weather most rocks. However, as the wind moves over the ground, it tends to pick up very small particles of dust or even fine grit. As this grit and dust blows over rocks with the wind, the rock becomes abraded by the grit and dust. Over time, this will erode and weather the rocks.
Deflation is the removal of worn rock by the action of wind carrying sand or small particles that erode the surface of the rock over time.
Wind can erode various types of rock formations into spherical shapes over time. Some common examples include ventifacts, which are rocks shaped by wind-blown particles, and concretions, which form from mineral precipitation around a nucleus. Wind can also erode softer rock layers within harder rock formations, creating round boulders known as "ventifacts."

well, think about it, wind can erode ALL size of rocks, wind does its job, which is eroding rocks.

moves small rock and hits it into big rock
Wind can pick up small aggregates and soil particles and displace them in another soil series. Wind can also erode rocks by picking up particles of sand that then slowly erode at the exposed rocks.
Wind rocks, also known as ventifacts, are rock formations that have been shaped by the erosive effects of wind-driven particles such as sand or sediment. Over time, these particles can erode away softer parts of the rock, leaving behind unique and often smooth surface patterns. Wind rocks are commonly found in arid and windy regions.
The wind has molecules (you can feel it when you fan yourself) and these molecules can carry very tiny pieces of rock. The wind takes tiny pieces of rock each year and, of course, it takes a long time to erode.
Wind can cause weathering of rocks through "sandblasting", the abrasion from wind carried particles, and through the movement of wind created waves that can weather rocks from applied and hydraulic force.
