The Prime Meridian is defined as which of the following?

• A. 180 Degrees Longitude
• B. 0 Degrees Latitude
• C. 0 Degrees Longitude
• D. 90 Degrees Longitude

Answer: (C)

The Prime Meridian is the reference line for measuring longitude, defined as 0 degrees longitude. It runs north to south and passes through Greenwich Observatory in London, serving as the starting point from which all east or west measurements are made. This line divides the globe into Eastern and Western Hemispheres, with longitudes increasing to 180 degrees east or west from it. Knowing that, the other options refer to different geographic lines: 180 degrees longitude is the line opposite the Prime Meridian (near the International Date Line), 0 degrees latitude is the Equator, and 90 degrees longitude is just another meridian away from the Prime Meridian.
