Best Answer

If you take a ruler and make one measurement up from the floor and one

measurement from the corner of the room, you can come up with two numbers

that exactly describe the location of any point on the entire wall.

If you do exactly the same thing on the globe, you can come up with two numbers

that exactly describe the location of any point on the entire Earth. You just have to

know where each measurement starts from. And the rulers are printed right there

on the globe for you.
