What were the 3 causes of the dust bowl?
This increased exposure to erosion was revealed when an unusually severe drought struck the Great Plains in 1934. The grass covering the prairie lands for centuries held the soil in place and maintained moisture, but with deep plowing from increased farming, the grass holding the soil was eliminated. The drought conditions caused the topsoil to grow very dry and loose and it was simply carried away by wind which, in turn, kicked up immense dust clouds which further prevented rainfall. It was not until the government promoted soil conservation programs that the area began to become rehabilitated.
