Where does the prime meridian run through?

• A. Tokyo, Japan
• B. Greenwich, England
• C. Paris, France
• D. New York, USA

Answer: (B)

The prime meridian runs through Greenwich, England. This line is significant as it is defined to be 0 degrees longitude, serving as a reference point for the global coordinate system used in navigation and geography. The prime meridian was established at the International Meridian Conference in 1884, where delegates from various countries decided on Greenwich as the standard reference point for timekeeping and for the world’s longitudinal mapping.

This makes it a critical point on the world map, marking the division between the Eastern and Western hemispheres. Other cities mentioned in the options, such as Tokyo, Paris, and New York, are located in different longitudes and do not intersect with the prime meridian, underscoring the importance of knowing the location of major geographical lines like the prime meridian for understanding global navigation and time zones.
