How did the drought contribute the Dust bowl? How did poor agricultural practice contribute to the dust bowl?
How did high temperatures cause the dust bowl?

Explanation:

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent the aeolian processes (wind erosion) caused the phenomenon.

Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl. ­The seeds of the Dust Bowl may have been sowed during the early 1920s.
