If the world's water was on land

[dkatwa]

If all the water currently in the seas, was on land, how high would the water be?

Remember this popping up in a news feed some time ago.

I think it would fall off......






(What if you put it on a conveyor belt, though....?)

Surely all the worlds seas are on land?

It's just that that land is under water.

top of my head figures and pub maths- about 29300ft

Avg ocean depth 12100ft, sea to land ratio 70.8:29.2

Goggle is your friend for this kind of nonsense- http://water.usgs.gov/edu/earthhowmuch.html

It would be an interesting world, what with all the water piled up on the land and the seas bone dry. Evn Moses would need some practice to do that.

[CrutyRammers]

Surely it would have to be frozen first? And that would make it bigger.

well, it might be a silly question but if I knew the height, I might be able to gauge how big the oceans truly are.

You'd need to know the size of the oceans to answer the original question!

This.

If the water covered the surface of the earth evenly then it would be about 5.3km deep. (Using volume of spherical shell, Earths diameter of 12742km and volume of sea water of 1.35 billion cubic km)

If just considering the currently exposed land then ~12.3km deep.

Finally, an answer that makes sense to a person of below average intelligence, like me...thanks :-)

What I do recall is that in a documentary I was watching a while back about the theory that comets bought the water to earth they stated that 1-2% more water and there would be NO dry land on the planet. Small margin! Good job God knew what he was doing when he put the planet together.
