It's flat, innit? It's a trick question? :p :

Is a circle round?

22,000kms?? Hmmm (:

20000 Miles at a quick guess !

Doesn't it change shape due to gravitational forces from the Moon, or the rings around Uranus or something????

Well, the shape depends upon the number of approximations required for the definition, doesn't it?
ie: the 1st approximation is a sphere, the 2nd an ellipsoid of revolution, etc.
The geoid is actually most like a slightly squashed golf ball (with the dimples), when it comes down to it.
So I'd guess that your question needs some clarification as to your expectation.

I remember these threads from way back...thanks for bringing 'em back!

The deepest point of the Earths ocean is Challenger Deep, but which country is located to the north of Challenger deep?

United States.

You're off by a Q there Mark :p :

Yep, good to have this thread back! Let's try to keep this one going :up:

As for the current, somewhat cryptic Q, I haven't the foggiest...

Donkey-dung round :mark:
