The Dust Bowl · US History

What was the environmental effect of 'static electricity' during the most severe dust storms?

  1. It caused massive wildfires across the Plains
  2. It led to the invention of the first electric tractor
  3. It caused the airborne dust to gradually turn into a solid, glass-like substance over time
  4. It shorted out car engines and made it painful for people to touch one another
Show answer and explanation

Correct answer: It shorted out car engines and made it painful for people to touch one another

The friction of the dust particles in the air created intense static charges. This electricity was strong enough to knock people down, kill radio signals, and cause blue sparks to jump between objects.
