When you cross the Prime Meridian, you transition from the Western Hemisphere to the Eastern Hemisphere or vice versa. The Prime Meridian, located at 0 degrees longitude, serves as the reference line for measuring longitude. Crossing it can affect time zones, as you may shift from one time zone to another, impacting local time. It also marks a significant point in navigation and geography, as it divides the Earth into eastern and western halves.
