Answer: Wind Erosion
Explanation: Sandblasting of the surface bedrock in a desert is the result of wind erosion. Sand-size particles are picked up and transported by wind across great distances in desert environments. When the sand laden wind erodes bedrock, the surface becomes smoother and somewhat polished. Eroded oxides, such as iron and manganese oxides, may add a thin layer of colored material called desert vanish.
