Final answer:
The most important effect of the Dust Bowl was the flood of migrants from the Great Plains to the West.
Step-by-step explanation:
The most important effect of the Dust Bowl was the flood of migrants from the Great Plains to the West.
The severe storms and drought that occurred during the 1930s led to the destruction of farmland, causing many farmers to abandon their land and seek opportunities elsewhere. Approximately 800,000 farmers and others who were dependent on the farming industry were displaced by the Dust Bowl. Most of these individuals headed to the West, particularly California, in search of available jobs.
This migration of people from the Great Plains to the West had significant social, economic, and cultural impacts on both the migrants and the regions they moved to.
