Extensive farming combined with severe drought caused the Dust Bowl in the 1930s. Deep plowing on the Great Plains killed the natural grasses that kept soil in place, and the topsoil turned to dust and blew away.
Dust storms are caused by a number of factors:   Prolonged drought-lack of rain to settle the soil, and to promote plant growth, which in turn helps keep the soil in plac â¦ e.  Deforestation, leaving the ground open and exposed.  Excessive heat and weather conditions, which can lead to the raising up of high winds.
