Briefly explain the prime meridian and one common misconception about it.

## The Prime Meridian The **prime meridian** is the line of 0° longitude that runs from the North Pole to the South Pole through Greenwich, London. It serves as the reference point from which all other longitudes are measured (east and west up to 180°). ## Common Misconception Many people believe the prime meridian passes through Greenwich due to some inherent geographic or scientific significance. **This is false.** The location is entirely arbitrary—it was chosen at the 1884 International Meridian Conference primarily because: - British maritime charts were widely used globally - The Greenwich Observatory was already prominent in navigation - It was largely a political decision reflecting British influence at the time Any meridian could have served as the prime meridian; there's nothing physically special about the Greenwich line.
