Attrition- Attrition is the mechanical wear and tear of particles blasted by the wind in the air while being transported by wind. Since it is deposited in areas of low-rainfall where the ground has grasses to bind the particles of dust, the loess stands without being removed further by wind. While above height of average 2 meters, erosional process is again very low. These processes occur in a variety of environments, including the coastal zone, cold and hot deserts, and agricultural fields. These bed loads are made of sand-sized particles which move by saltation. Why does erosion occur and how does it affect humans?
