The wearing away of rock surfaces by wind-blown sand and dust is a type of mechanical weathering. This is because the rocks are physically broken down by the abrasive action of the sand and dust particles, rather than being chemically altered or decomposed. Other examples of mechanical weathering include freeze-thaw cycles, root wedging, and abrasion by flowing water or ice.
