Question

1. which of the following was not a cause of the dust bowl?

options:

• drought
• high winds
• thick layers of prairie grass
• overproduction of crops

Explanation:

The Dust Bowl was caused by severe drought, strong high winds that carried dry topsoil, and overproduction of crops which stripped the prairie of its native protective vegetation. Thick layers of prairie grass actually prevented soil erosion and were removed by farming, so they were not a cause of the Dust Bowl.

Answer:

C. Thick Layers of Prairie Grass
