The meridian that runs through Greenwich, England is called the ___________

• A. Prime meridian
• B. Equator
• C. International Date Line
• D. Tropic of Cancer

Answer: (A)

Longitudes measure how far east or west you are from a reference line. The line that passes through Greenwich, England is the Prime Meridian, defined as 0 degrees longitude. This serves as the starting point for measuring east and west and helps set standard time zones. The Equator, in contrast, is the 0 degrees latitude line that circles the Earth and separates north from south. The International Date Line is located roughly opposite the Prime Meridian at about 180 degrees longitude, and the Tropic of Cancer is a latitude line at about 23.5 degrees north. Understanding that longitude lines run from pole to pole and that the Prime Meridian is the zero reference helps see why Greenwich is associated with the Prime Meridian.
