Abrasion, attrition, and deflation are processes of wind erosion. Abrasion is the process by which wind carries small rock particles that strike and scrape against rocks, breaking them apart. Attrition is the process by which these small rock particles collide with each other, breaking into even smaller particles. Deflation is the process by which wind removes and carries away loose particles, such as sand or dust, leaving behind a surface that is more compact and solid. Together, these processes can erode and shape landscapes in arid regions with little vegetation cover, such as deserts.
