A massive drought and heat wave caused the Dust Bowl in Texas, however, the damage was compounded by the lack of prairie grass. Explain why prairie grass was important and how replacing the grass with crops helped cause the dust in the Dust Bowl

The grass helped keep soil in the ground

Explanation:

The prairie grass spread roots in the earth/dirt and kept it in place and prevented soil/wind erosion. The removal of this grass and introduction of less effective cash crops led to much more soil being eroded and picked up by the wind. This contributed to the dust bowl

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
