All the air & water on Earth compared to Earth
We often hear about how 70% of the Earth’s surface is water, and while this is certainly a legitimate way of measuring the water on the earth, what about comparing the volume of the Earth to the volume of water on the Earth? What about the same thing with air? Well, Dan Phiffer has posted an image (found online) that shows just this.
Phiffer explains:
Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc. Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth.
If you want to find out the math that suggests this is an accurate picture: go read the whole thing.
