The Dust Bowl, which happened during the 1930´s originated in the South and its devastation and effects moved on to affect not just the Southern Plains but also the Great Plains. The absence of rainfall, the intense movement of strong winds and continuous dust were part of the factors that affected everything in life, from the economy of families to their welfare and even comfort, to their health. It was a time of great drought, which coupled with the Depression of the 1930s, increased the poverty levels, especially in rural areas. In response to the need for food and income to be generated, many farmers decided to replace the natural grasses that grew in the plains for winter wheat and this action, coupled with the lack of rainfall, led to a furthering of the drought problem and also to land erosion.

This is why the correct response is C: Replacing natural grasses to plant winter wheat led to topsoil erosion.
