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.
They all seem to hint at humans being the root cause of the Dust Bowl. 4) What are 4 causes of the Dust Bowl that Professor Hurt identifies? The four causes identified by Hurt are drought, crop failure, land abandonment, and soil erosion. 5) In what ways are Worster and Hurtâs accounts different? Worster attributes the Dust Bowl to American culture, while Hurt attributes it to a chain of events.
