Frequently Asked Questions
What is the difference between the Equator and the Prime Meridian?
The Equator is the 0° latitude line running east–west, dividing Earth into the Northern and Southern Hemispheres. The Prime Meridian is the 0° longitude line running north–south, dividing Earth into the Eastern and Western Hemispheres.
Which one measures latitude and which measures longitude?
The Equator is the reference line (0°) for latitude; the Prime Meridian is the reference line (0°) for longitude.
Where does the Prime Meridian pass?
The Prime Meridian passes through Greenwich in London, UK, and is used as the basis for standard time (GMT).
