Have you ever wondered why hot air rises if it's supposed to be warmer up high, yet mountaintops are freezing cold even on sunny days? This classic science question reveals one of the most elegant and misunderstood principles in atmospheric physics. The answer has nothing to do with being closer to the sun and everything to do with how air behaves when it expands under lower pressure.As air rises, it encounters thinner atmosphere and expands, causing its molecules to spread out and lose energy.
This process, known as adiabatic cooling, can drop temperatures dramatically with altitude. In this video, we break down the physics step by step with clear demonstrations, real-world examples from mountains and weather systems, and the surprising reasons why this same principle powers hurricanes, creates clouds, and shapes our planet's climate. Once you understand it, you'll never look at a mountain the same way again.
If Heat RISES, Why are Mountaintops FREEZING?
