Final answer:
The Dust Bowl in the 1930s was mainly caused by drought and poor land management practices, leading to severe wind erosion and the stripping of fertile topsoil.
Explanation:
The main cause of the Dust Bowl in the 1930s was a combination of drought and poor land management practices. The severe wind erosion of soil in the Great Plains region resulted in the stripping of topsoil by wind, forming immense dust clouds that traveled long distances.
This ecological catastrophe known as the Dust Bowl was primarily caused by a lack of rain, leading to dry and eroded soil that was easily carried away by high winds. The resulting loss of fertile topsoil caused significant agricultural and environmental damage, leading to widespread migration and devastation.
