The Prime Meridian is the imaginary line of longitude set at 0°, running from the North Pole to the South Pole. It passes through Greenwich, England, and serves as the starting point for measuring longitude east and west. The Prime Meridian also plays a key role in determining time zones, dividing the Earth into the Eastern and Western Hemispheres.

The Prime Meridian is an imaginary line of longitude established at 0°, running from the North Pole to the South Pole, and passing through Greenwich, England. It serves as the global reference point for measuring longitude, marking the division between the Eastern and Western Hemispheres. This line is crucial for navigation, mapping, and timekeeping, as it is the starting point for the world’s longitudinal coordinate system. The establishment of the Prime Meridian also led to the creation of the Greenwich Mean Time (GMT), which is the basis for time zone calculations worldwide. The Prime Meridian’s role in geography and global coordination is fundamental to understanding Earth’s layout.
