mechanical or physical weathering
The breakdown of rocks due to wind is an example of physical weathering. As the wind blows sand and other particles against the rocks, it can cause them to erode and break apart over time. This process of mechanical weathering contributes to the gradual reshaping of the Earth's surface.
Mechanical weathering is caused by physical forces breaking down rocks into smaller pieces. This process can be triggered by factors such as temperature changes, ice formation, and the action of plant roots. Ultimately, these forces lead to the physical disintegration and breakdown of rock material.
The other cause of mechanical weathering is abrasion, which occurs when rocks are worn down by friction from other rocks or sediments. It involves the breaking and wearing away of rock surfaces through the mechanical action of other rock or sand particles.
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
Sand movement is erosion because it deals with the transportation of already weathered materials. However it is worth noting that the movement of sand can also cause weathering as the moving sand particles can act as an abrasive causing mechanical weathering.

The agent of mechanical weathering in which rock is worn away by the grinding action of other rock particles is called abrasion.

The agent of mechanical weathering you are referring to is called abrasion. It occurs when rocks are physically worn down by the friction and impact of other rock particles.
Abrasion is the grinding and wearing of rock surfaces through mechanical action of other sand particles.

The original source of sand and other particles is primarily rocks. Through the process of weathering and erosion, rocks break down into smaller particles that eventually become sand. Other particles, such as silt and clay, also come from the erosion and breakdown of rocks and minerals.
Abrasion in mechanical weathering occurs when rocks and minerals are worn down and broken apart by the constant rubbing and grinding action of other particles such as sand, pebbles, or glaciers. This process leads to the physical fragmentation and erosion of the material over time.
