How much do clouds weigh?

Have you ever wondered how much clouds weigh? Would they be light like cotton or incredibly heavy like elephants? Today you can discover every secret inside them! Keep reading to find them out!

What are clouds made by?

Firstly, we should know what cloud are made by as well as how they are formed, don’t you think little scientist?

Clouds are formed by drops of water and tiny ice crystals that are in the atmosphere. The sky is usually filled with water, although we cannot perceive it since those particles are so minuscule that are imperceptible for human’s eyes. Those drops can be transformed into water steam so that clouds are created!

How clouds are made


When we lay down to look at the sky to observe calmly those “cotton sheet” floating through the sky, first thing we might do is start imagining… and we then realise that some clouds have specific shapes! (or that is what we think) However, if we looked through into them, they could tell us much more things than that!

As it has already been explained, clouds can be made by drops of water and/or ice crystals. It depends on their height respectively to atmosphere. It means that if they are over atmosphere (more than 6 km from the floor), these will be constituted by ice, while they will be made by water if they are below that height.

But, how much do they weigh?

As some clouds are made by ice, it is normal thinking that they might be the heaviest ones, but, what exactly is their weight? Well, these “soft cotton sheets” made by ice can weigh up to the weight of 200 thousand elephants!! Shocking, don’t you think little scientist? Even normal white clouds like the ones we can see every day, can weigh up to 5 tons, which means the same as 100 elephants!

And how is rain formed?

After all of this, a doubt has come up to our mind… if clouds are made by water and ice, why don’t rain every time there are clouds in the sky?

It is simpler than it looks like, little scientist. Normally, clouds are less dense than air, so it keeps them floating. However, when clouds’ density starts increasing, their weight also increases, so the drops inside them begin to fall. It starts raining.


  • There are different types of clouds. There are called after its shape or the place where they are.
  • Clouds reflex heat from the Earth at night, keeping the ground hot.
  • Clouds investigations are essential to understand the climate of a planet.
  • NASA has some satellite in the space whose main purpose is to study clouds.
  • Clouds in Jupiter are made by a gas called amonia.
  • Mars has clouds completely similar to the ones on the Earth, made by water.

Now you already know every about clouds, little scientist. Go out and observe them! You will realise much more thing than you used to. And, don’t forget telling it your friends, they will be so shocked as you when they will know all about clouds!
