Big Blue Marble: Water and Air

Global water and air volume. Conceptual computer artwork of the total volume of water on Earth (left) and of air in the Earth's atmosphere (right) shown as spheres (blue and pink). The spheres show how finite water and air supplies are. The water sphere measures 1390 kilometers across and has a volume of 1.4 billion cubic kilometers. This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the atmosphere. The air sphere measures 1999 kilometers across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometers of the atmosphere.

I'd love to see one more showing all of the oil in the world.

Nice idea, but I hate seeing a globe with a distorted map projection. I live in England, I *know* it is not that big.

The ball of water leaves out the underground water, which dwarfs the oceans. Double the size of the water ball and you'd have it.
