Final answer:
The Dust Bowl was caused by poor agricultural practices and drought during the Great Depression, leading to severe dust storms that eroded millions of acres of topsoil in the Southern Great Plains.
Step-by-step explanation:
The Dust Bowl resulted from poor agricultural practices and drought during the era known as the Great Depression. The Dust Bowl was an ecological disaster that took place in the mid-1930s, primarily within the Southern Great Plains of the United States.
A combination of severe drought, over-farming, and the removal of prairie grasses led to the erosion of 100 million acres of topsoil, which turned to dust and was blown away by massive dust storms. These storms led to the displacement of many families and the devastation of the American agricultural sector during this period.
