Question

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

Explanation:

The Dust Bowl was characterized by severe soil erosion. Poor tillage (like over - plowing) and wind led to soil being picked up and carried away. The first option describes soil erosion from wind and poor plowing (a type of tillage practice). The second option is incorrect as poor tillage wouldn't improve soil structure to reduce runoff. The third option is wrong because poor tillage would harm, not enhance, crop yields.

Answer:

A. soil erosion caused by wind and poor plowing techniques
