What Is Important, To Scale

Water/Air in proportion to Earth

A fascinating image. On the left is all of the water on Earth, roughly 1.41 billion cubic kilometers (including oceans, ice, lakes, rivers, ground water, clouds… etc) proportionally represented by the blue marble sitting over Italy. On the right, all of the air in the atmosphere, roughly 5,140 trillion metric tonnes, proportionally represented by the pinkish marble. I would have thought both to be somewhat larger, the reality being that we only have a tenuously thin skin of both water and air.

I found this to be quite surprising, a bit startling, and a little scary.
