What are clouds made of? How do clouds form? How do they stay afloat? How much does a cloud weigh?

For such a common sight in our everyday lives, there are definitely a lot of interesting questions you could ask of clouds.

This video goes about tackling them and some of the answers might surprise you.

Although clouds might look like they are made of gas, they are actually a large mass of tiny drops of liquid water or ice crystals Clouds are usually formed when air rises and the water vapour within it cools. When cooled, the water vapour collides with and sticks to tiny particles floating in the air - these are known as condensation nuclei, which include aerosols such as salt and dust. As the vapour rises and cools, these nuclei provide the surface for the vapour to condense onto. When enough vapour condenses around the nuclei, a cloud droplet is formed. These droplets are so small that a cubic metre of air contains 100 million of them. However, combined to make a cumulus cloud, they can weigh as much as 500 tonnes. That’s roughly 100 elephants. Thankfully the individual water droplets, unlike elephants, are so tiny and spread out that they stay afloat.

Sometimes these water droplets combine to become larger drops or crystals. And if they become large enough and too heavy, they will gradually fall from the sky as - you guessed it - precipitation

me in my mind:clouds look like gas but ts made of different things
.this is cool.its made of watercrystals and some other stuff

The process of condensation plays a very important role in bringing back water to earth surface

Now I have so many more questions. How do they stay up? A strange comment below suggests they are "resting" on the drier air beneath them. But isn't moisture and air always rising if it's being heated by the earth?

I do understand how we *see* clouds, that's geometric scattering. I've always understood that. I'm still confused how a cloud exists though :)

what you've explained here is why water can be suspended in the atmosphere (in literally every cm2 of the atmosphere), not why or how a visible clouds form
