All of Earth’s water into a sphere, how big would it be?

[Fr8monkey]

Imagine the Earth in your mind's eye. Now round up all the water on the planet into a sphere (we're talking oceans, icecaps, atmosphere, everything — even the water bound up in you and me). How big do you think that sphere would be compared to the Earth?

Got your answer? Our water sphere would have a diameter of 1,385 kilometers (about 860 miles). A sphere this far across would have a volume equal to about 1,386 million cubic kilometers (roughly 332,500,000 cubic miles). Those might sound like big numbers (and they certainly are big numbers) but wait until you see this sphere beside the Earth.

I've seen one of those before, with the sphere for the air as well. It's pretty cool.

America has stolen our water, this means war.

Looks like the beginning of a really weird anime.

TL;DR, looks like the beginning of an anime.

Doesn't look like it'd be worth the trouble to make.

Land implies you can stand on it. Earth is actually mostly rock.

lolol rock

Earth implies soil. We don't often associate the word with, say, magma.

you were supposed to read that sarcastically.

earth is mostly iron, deal with it

 

[Berzerker]

how do they know how much water is locked up inside the earth?

 

[attackfighter]

magic

 

[Berzerker]

thats how the water got there

but maybe this is a good thread to discuss the origin of Earth's water...

Well, no. Iron makes up a plurality of the chemical composition of the Earth, but not "most". It's only, what, about a third?

 

[Ziggy Stardust]

That much eh? Wow, I knew it was a lot.

I'm guessing that is by mass (well, actually, I'm pretty sure, volume would be silly)

 

[Berzerker]

and enough to make 3 planets

maybe we can discuss the origin of Earth's iron too

 

[Ziggy Stardust]

Broccoli?

 

[Antilogic]

No, it's clearly all that spinach with it's super-iron forearm-popping content!

Oh, wait, that's not it either.
