There is no single meridian of longitude that divides the earth in half. Each meridian

is a semi-circle drawn between the north and south poles.

However, if you take any meridian and join it to the one marking the longitude exactly

180 degrees away from the first one, then together they form a circle that divides the

surface of the earth in half.
