Where is the Greenwich Meridian found?
Greenwich meridian, imaginary line used to indicate 0° longitude that passes through Greenwich, a borough of London, and terminates at the North and South poles.
What is Greenwich meridian and why is it important?
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.
How was the Greenwich Meridian decided?
The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. They chose the meridian passing through the Royal Observatory in Greenwich, England.

Why did the Greenwich Meridian move?
For supporting evidence, the scientists also analyzed the differences in the coordinates of many former timekeeping observatories to affirm that the apparent longitude shift at Greenwich is a localized effect due to the direction of gravity at Greenwich, and not a global shift in the world’s longitude system.
Why is it called Greenwich Mean Time?
