Cool Image: Earth's Water and Air

I'm not even going to try taking credit for this image, the caption, or the accuracy of each. However, it seems like everything is accurate. Cool!


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.
