8. In the below pictures, wind is picking up dirt and moving it, causing the sand to form piles or dunes. These pictures were taken during the 1930s when the south-central United States became known as the Dust Bowl. Grass had been removed from the land to farm, but because of a massive drought, the soil dried out and was easily blown away. Wind erosion can usually be prevented by planting trees and grasses because their roots help hold the soil in place.
