Answer: Hot ground and calm, clear weather
Air heated by the ground rises quickly and can begin to spin.
- Q2: How do dust devils differ from tornadoes?
Answer: They form from the ground up, not from storm clouds
Tornadoes descend from thunderstorms; dust devils rise from heated ground.
- Q3: How dangerous are most dust devils?
Answer: Usually weak and short-lived
Most last a few minutes, though rare strong ones can damage light structures.
- Q4: What is a dust devil called in Australia?
Answer: A willy-willy
The term is widely used in outback regions.
- Q5: How have dust devils helped Mars rovers?
Answer: By blowing dust off solar panels
Spirit and Opportunity got power boosts after cleaning events.
- Q6: What do dust devils leave on the surface of Mars?
Answer: Dark, winding tracks
Orbiters photograph their tracks across dusty plains.
- Q7: When do dust devils most often form?
Answer: Afternoons on sunny days
The ground heats most strongly in the afternoon.
- Q8: What is a fire whirl?
Answer: A spinning column of flame and smoke
Intense heat from fires can create similar vortices.
- Q9: In some Navajo tradition, how are dust devils viewed?
Answer: As spirits, sometimes associated with ghosts
Many cultures have stories about whirlwinds.
- Q10: How tall can large dust devils become?
Answer: Up to about a kilometer or more
Most are small, but some reach great heights over deserts.
Dust Devil Quiz – Whirlwinds on Sunny Days
Dust devils are spinning columns of air that pick up dust and debris. They form on hot, sunny, calm days when the ground heats the air above it, which rises quickly and begins to rotate.
Unlike tornadoes, which descend from thunderstorm clouds, dust devils rise from the ground and are usually weak and short-lived. In Australia they are called willy-willies, and similar spinning columns of flame called fire whirls can form in wildfires.
Dust devils also occur on Mars, where orbiters photograph their dark tracks. NASA's Spirit and Opportunity rovers benefited when dust devils blew dust off their solar panels, extending their missions.
