Clouds look light and fluffy, but they're surprisingly heavy.
When you're flying in an airplane above a blanket of clouds, the pillars of white and gray look soft, fluffy and lighter than air. But don't be fooled — those bouncy-looking clouds are much, much heavier than they appear.Clouds are composed mainly of air and millions of tiny water droplets, which form when water condenses around a"seed" particle. Seed particles can be anything from nitric acid to vapors released by trees, but they are generally very tiny.
That's approximately the weight of 100 elephants suspended above your head."It's really impressive," Soroohsian said. However,"the entire volume of the cloud is not just the droplets; there's air, too," Sorooshian said. If someone wanted to take LeMone's calculations a step further, they could factor in the weight of the air between each droplet.—How much does the soul weigh?
Heat convection also helps keep the drops aloft."A cloud is actually less dense than the air directly below it," Sorooshian said. As warm air rises, it becomes more buoyant than the cold air beneath it, like a layer of foam on top of a latte.
