How much does a cloud weight?

Answer 1

To calculate the weight of a cloud, you first have to figure out how dense it is. The average density of a cumulus cloud is around half a gram of water per cubic meter. Second, you need to determine how big the cloud is, presumably by measuring its shadow while the sun is above it. A typical cloud is about a kilometer across and roughly cube shaped, meaning it has a volume of one billion cubic meters.

Using this formula, scientists have determined that the average cumulus cloud weighs around 1.1 million pounds.

Answer 2

A cloud can weigh anywhere from less than a million pounds to several million pounds, depending on its size and density. However, since clouds are made up of tiny water droplets or ice crystals suspended in the air, their weight is difficult to measure accurately.

Answer 3

What you are looking for is the weight of a cloud? Well scientist Peggy LeMone says that a little cumulus cloud weighs about the same as 100 elephants! A thunderstorm cloud is like 200,000 elephants! 🐘

Answer 4

According to scientists, the weight of the average cumulus cloud is 1.1 million pounds! Think about that for a moment. This means that at any given moment, there are millions of pounds of water floating above your head. That is the equivalent of a hundred elephants.

Answer 5

They may look all light and fluffy, but the reality is that clouds are actually pretty heavy. Researchers have calculated that the average cumulus cloud - which is that nice, white fluffy kind you see on a sunny day - weighs an incredible 500,000 kg (or 1.1 million pounds!).

How do you work that out? First of all, you need to realise that clouds are made up of a lot of tiny water droplets, which means that they must have some mass. The next step is to then work out how dense your cloud is.

So back to those cumulus clouds. Scientists have worked out that the water density of this cloud type is around 1/2 gram of water per cubic metre. So, as Matt Soniak writes over at Mental Floss, that's about a marble's worth of water in a box large enough for you and a friend to sit in. Not very much. Obviously, the density of other types of clouds would be much greater, but let's stick to the cumulus for now.

Once you've worked out the density of your cloud, you need to work out how big it is, which is a measurement that also varies widely. Peggy LeMone, who led a lot of the cloud weighing research at the US National Centre for Atmospheric Research, calculated that the average cumulus is about a kilometre across and roughly has the shape of a cube, so it's as tall as it is wide.

Do the maths on that, and you've got a cloud with a volume of one billion cubic metres. Times that by your density and you get your answer of almost 500,000 kg. Or, as LeMone explained it to Soniak, think of that as 100 elephants.

So now the real question is, how does all this massive weight stay afloat in the sky? What's stopping it from collapsing on our heads at any moment? *Looks up nervously*.

To start with, this weight isn't all concentrated in one point, it's obviously spread out over a huge space. Clouds are also made up of water droplets that are sometimes so tiny that gravity has hardly any effect on them. And because of condensation, clouds are actually bouyant.

Perhaps even more surprising is the fact that a cloud is actually less dense than dry air, so that keeps them floating, as Soniak explains.

Answer 6

2 the answer is 2.

If they fell on you, you would die. As clouds weigh 2 much

Answer 7

That would depend on the amout of material it is made up from.

Answer 8

The average cloud weighs about 500,000 pounds.

Answer 9

its a lot but when your in them you cant feel anything

Answer 10

Researchers have calculated that the average cumulus cloud weighs 500,000 kg (or 1.1 million pounds).
