How could you draw the prime meridian?

Answer 1

On a globe, draw the shortest line you possibly can between the north pole and

south pole, and make sure it passes through Greenwich, a suburb of London in

England.

You can make sure it's the shortest possible line by stretching a rubber band

between the north and south poles of the globe. The rubber band will just

naturally keep pulling itself shorter and shorter until it can't get any shorter.

Answer 2

The Prime Meridian is an imaginary line that runs from the North Pole to the South Pole. You can draw the Prime Meridian using a straight line on a map, starting from the top of the map (North Pole) and extending down to the bottom (South Pole), passing through Greenwich, England, which is the location where the Prime Meridian is defined to be 0 degrees longitude.
