Which circle is located at approximately 66.5 degrees South?

• A. Arctic Circle
• B. Equator
• C. Antarctic Circle
• D. Tropic of Cancer

Answer: (C)

Understanding major lines of latitude helps locate places north or south of the Equator. The Earth has polar circles at about 66.5° from the Equator: one up north and one down south. The Tropic of Cancer sits at about 23.5°N, the Equator at 0°, and the Arctic Circle at about 66.5°N. A line at approximately 66.5°S lies in the southern polar region, known as the Antarctic Circle. This line marks the southern boundary where, depending on the season, the sun can be above or below the horizon for extended periods. So the Antarctic Circle is the correct identification for a location at about 66.5°South.
