The prime meridian separates the eastern hemisphere from the western hemisphere. Halfway around the world, at 180 degrees longitude, is the International Date Line. The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth..
Beside this, why is the prime meridian where it is?
The line in Greenwich represents the historic Prime Meridian of the World - Longitude 0º. Every place on Earth was measured in terms of its distance east or west from this line. The line itself divided the eastern and western hemispheres of the Earth - just as the Equator divides the northern and southern hemispheres.
Subsequently, question is, why does the prime meridian run through Greenwich? The Prime Meridian Line, which represents zero degrees longitude, is an imaginary line and could have been chosen anywhere. Greenwich was chosen as the Prime Meridian because it was voted as the prime candidate by an elite group of astronomers during the International Meridian Conference, 1884.
