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:

During the Dust Bowl, poor tillage practices like improper plowing left soil loose and vulnerable. Wind - driven soil erosion was a major problem exacerbated by these practices. Frequent and ineffective tillage would not enhance crop yields during the Dust Bowl and improved soil structure would not be associated with poor tillage, reducing water runoff is not an issue exacerbated by poor tillage but rather the opposite.

Answer:

soil erosion caused by wind and poor plowing techniques
