Question

what problem was exacerbated by the poor tillage practices during the dust bowl?
enhanced crop yields from frequent and ineffective tillage
soil erosion caused by wind and poor plowing techniques
reduced water runoff due to the improved soil structure

Explanation:

• For the first option: Poor tillage practices would not enhance crop yields; in fact, they harm soil health, so this is incorrect.
• For the second option: During the Dust Bowl, poor plowing (tillage) techniques left soil exposed, and wind led to severe soil erosion, which matches the problem's context.
• For the third option: Poor tillage does not improve soil structure to reduce water runoff; it degrades soil structure, so this is incorrect.

Answer:

B. soil erosion caused by wind and poor plowing techniques
