Detailed explanation-1: -What circumstances conspired to cause the Dust Bowl? Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl.
Detailed explanation-2: -Due to low crop prices and high machinery costs, more submarginal lands were put into production. Farmers also started to abandon soil conservation practices. These events laid the groundwork for the severe soil erosion that would cause the Dust Bowl.
Detailed explanation-3: -All tornadoes produce damage, but the most violent ones can cause automobiles to become airborne, rip homes to shreds, and turn broken glass and other debris into lethal missiles. The biggest tornado threat to human beings is from flying debris in the wind.
Detailed explanation-4: -Tornadoes develop from severe thunderstorms in warm, moist, unstable air along and ahead of cold fronts. Such thunderstorms also may generate large hail and damaging winds. When intense springtime storm systems produce large, persistent areas that support tornado development, major outbreaks can occur.
