Imagine if Earth's atmosphere flipped upside down—things would get wild! Normally, warm air stays near the surface, and cooler air layers are above, but if it reversed, the sky would trap cold air near the ground. That means we’d be freezing at sea level while the tops of mountains could be toasty warm. Weather would go haywire—rain patterns would flip, and we might even see snow in the tropics while deserts could flood. Planes would have to deal with unpredictable turbulence as air currents would be completely messed up. The world would be unrecognizable, and scientists would be scrambling to figure out how to survive in this topsy-turvy new Earth!
