Which circle lies at approximately 66.5 degrees South?

Which circle lies at approximately 66.5 degrees South?

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

Answer: (D)

Think about how latitude lines are arranged. Circles of latitude run parallel to the equator, with the Tropics sitting near the equator at about 23.5 degrees, and the polar circles farther away. The Antarctic Circle sits at about 66.5 degrees south, making it the southern counterpart to the Arctic Circle in the north. Since 66.5 degrees south matches the Antarctic Circle, that’s the circle described. The Tropics of Cancer and Capricorn are much closer to the equator (around 23.5 degrees north and south), so they don’t fit this latitude.
