WORLD HISTORY

Detailed explanation-1: -When severe drought struck the Great Plains region in the 1930s, it resulted in erosion and loss of topsoil because of farming practices at the time. The drought dried the topsoil and over time it became friable, reduced to a powdery consistency in some places.

Detailed explanation-2: -During the Great Depression, a series of droughts combined with non-sustainable agricultural practices led to devastating dust storms, famine, diseases and deaths related to breathing dust. This caused the largest migration in American history.

Detailed explanation-3: -The strong winds that accompanied the drought of the 1930s blew away 480 tons of topsoil per acre, removing an average of five inches of topsoil from more than 10 million acres. The dust and sand storms degraded soil productivity, harmed human health, and damaged air quality.

Detailed explanation-4: -The Dust Bowl intensified the crushing economic impacts of the Great Depression and drove many farming families on a desperate migration in search of work and better living conditions.

Detailed explanation-5: -What circumstances conspired to cause the Dust Bowl? Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl. The seeds of the Dust Bowl may have been sowed during the early 1920s.
