What occurs during a wind erosion?

• Answer:

  Erosion occurs when strong winds blow removing the top fertile layer of soil. The top soil containing clay,loam and organic matter is carried away by strong winds to many kilometers and deposited elsewhere forming fertile surface soil especially in Europe and North America, where productive farming has developed. Dunes, formed by mounds of sand, move by strong winds burying oases and ancient cities. Sedimentation crusts are degraded on the surface of stripped soils, weathering the rocks with abrasion at their base where they are in contact with the soil. Sheets of sand traveling close to the ground degrades crops in semi-arid zones. Wind erosion reduces the nutrients and water in soil, making the environment drier. Only large rocks are left when the lose soil is slowly shifted afar by the wind.
