The Meridian Line

The Prime Meridian is an imaginary line that runs from the North Pole to the South Pole and passes through Greenwich, London. It serves as the starting point for measuring longitude, dividing the Earth into Eastern and Western Hemispheres. Established as the global standard in 1884, it helps determine local times and navigation coordinates, ensuring consistency worldwide. Think of it as the Earth’s central longitude line, around which time zones and maps are organized. This helps us know exactly where we are on the planet and coordinate activities across different locations.
