Question

which of the following was a major cause of the dust bowl? low amounts of wind poor tillage practices severe flooding

Explanation:

The Dust Bowl was a period of severe dust storms in the 1930s. Poor tillage practices (like over - plowing and improper farming methods) removed the protective layer of grass and exposed the soil, making it vulnerable to erosion by wind. Low amounts of wind would not cause dust storms, and severe flooding is not a cause of the Dust Bowl (in fact, the region was drought - stricken). So the correct option is the one about poor tillage practices.

Answer:

B. poor tillage practices (assuming the options are labeled A, B, C with A: low amounts of wind, B: poor tillage practices, C: severe flooding)
