What were the causes of the formation of Dust Bowls?
Answer:
- They occurred because of the persistent droughts in that area.
- The rains failed year after year and temperatures soared. The wind blew with ferocious speed.
- But ordinary duststorms became black blizzards only because the entire landscape had been ploughed over and the grass was ruined which could hold soil.
- When wheat cultivation had expanded dramatically in the early 19th century, zealous farmers had recklessly uprooted all vegetation, and tractors had turned the soil over and broken the soil into dust. The whole region had become a Dust Bowl.
