Erosion (wind) caused the soil of the Great Plains to expose.
I think it was a combination of poor soil use and drought.
The Great Plains were exposed when the glaciers retreated at the end of the last ice age. As the glaciers melted they left behind deposits of silt and rocks. This exposed the soil of the Great Plains which is composed of two distinct layers. The top layer is composed of a mix of clay sand and silt that is generally well-drained. The bottom layer is composed of a mix of clay silt and sand and is much less permeable. This combination of layers has allowed for the development of a unique ecosystem in the Great Plains.The exposure of the soil on the Great Plains was also a result of human activities. Europeans began to settle the area in the 1800s and began to plow the land. This process exposed the soil making it easier to plant crops. As the population of the Great Plains grew more and more land was plowed further exposing the soil.Overall the soil of the Great Plains was exposed due to a combination of natural forces and human activities. The glaciers melting at the end of the ice age left behind deposits of silt and rocks while human activities such as plowing the land further exposed the soil. This combination of forces has allowed for the development of a unique ecosystem in the Great Plains.

Since the Mixedwood Plains has a wet climate and plenty of precipitaion, the soil is mostly leached. Leached soil means that the soil has been exposed to too much wanter and the nutrients have sunken deep intothe ground so that the roots of the plant cannot reach them. At the same time, the mixedwood Plains has soil that is fertile and abundant for farming.

Wind erosion was the cause of soil loss on the great plains in the 1930's. --------------------------------------------------------------------------------------------------------- However to be susceptible to wind erosion the soil had to be exposed and the agent which did this was human farming - the plough.

The Great Dust Bowl
The Great Plains had fertile soil that made growing crops necessary, but during the drought, the soil dried out, turned to dust, and blew away.
Since the Mixedwood Plains has a wet climate and plenty of precipitaion, the soil is mostly leached. Leached soil means that the soil has been exposed to too much wanter and the nutrients have sunken deep intothe ground so that the roots of the plant cannot reach them. At the same time, the mixedwood Plains has soil that is fertile and abundant for farming.
Because the soil on the Great Plains had been plowed over for decades, by farmers that did not yet have the advantage of agricultural science, the soil was very loose and when the drought and winds came, the top soil simply blew away because there was nothing left to hold it down.

The Great Plains are drier and generally have lower average elevation compared to the Central Plains. The Great Plains also have a distinct ecosystem characterized by grasslands, while the Central Plains may have more varied vegetation due to differences in precipitation and soil conditions.
