Dust Devil
A dust devil is a spinning column of dust and air that forms in hot, dry conditions, typically reaching heights of 10 to 1,000 feet and lasting from a few seconds to minutes. It arises from intense surface heating that creates a rising current of air, which then rotates into a vortex, often lifting debris and posing minor hazards to outdoor activities. In today's climate studies, these whirlwinds provide insights into atmospheric dynamics and even help model weather on other planets.

Dust devils on Earth can generate small electric charges, sometimes triggering lightning-like sparks, but on Mars, they play a massive role in clearing dust from the planet's surface, as seen in images from NASA's Curiosity rover, which revealed devils up to 10 times larger than those on Earth and capable of exposing ancient rocks.
