Geography fun
2015-03-08 14:11The Earth is about 40,000 km around. (40,006 polar, 40,075 equatorial.) This isn't a coincidence: the 1790s French defined the meter such that 10,000 km was the pole-equator distance. (Picking that ratio to be close to an existing unit.)
The volume of the Earth is 1 trillion km3. 1.083e12 if you need more digits. This is a coincidence.
Everest is the highest point above sea level. (mean sea level? the nearest ocean?) The land furthest from the Earth's center is Mount Chimborazo in the Andes, which at 1 degree South benefits from the equatorial bulge, vs. the 28 N of Everest.
The northernmost point of land and the southernmost point of ocean are at 83 N and 83 S.
Puzzles:
(mine) What European country is due east of Florida?
(someone else) Which US state is closest to Africa?
