When winds blow sand or silt grains against rocks and other objects?

When winds blow sand or silt grains against rocks and other objects, a process called abrasion occurs. This mechanical weathering gradually wears down surfaces, smoothing rough edges and altering the shape of the rocks. Over time, this can lead to the formation of unique geological features such as ventifacts or hoodoos. Additionally, the transported sediments can contribute to the reshaping of landscapes in arid and semi-arid environments.
