Prime Meridian
A line running north to south around the center of the Earth
Real World Example
Imagine navigating through a crowded shopping mall where you need a central point to orient yourself and decide which direction to take for the various stores. Just like needing a central reference point in a mall, the prime meridian serves as a central line for navigation and orientation on the Earth. In this analogy, the shopping mall represents the Earth, the central point is the prime meridian, and the various stores symbolize different locations across the globe, all measured in relation to this central line running from the North Pole to the South Pole.
