Answer :
Answer:
Option B. The two basic causes of the Dust Bowl during the early 1930s were the over farming and drought.
Explanation:
During the early stages of the 1930s strong winds, clouds and drought rolled in the Midwest that ended up plaguing nearly 75% of the United States between 1931 and 1939. What mainly caused the Dust Bowl was the over farming made by all the new inhabitants of the Midwest semiarid areas, that moved there as a consequence of the big depression the country was facing. The over farming of those dry lands was combined with a drought that hit the land, and the result was an ecological disaster that affected millions of people.
