Which circle is located at approximately 66.5 degrees North?

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

Answer: (B)

Latitude measures how far north or south you are from the equator. The Arctic Circle sits at about 66.5°N because Earth’s axis is tilted about 23.5°, and 90° − 23.5° = 66.5°. This line marks the northern boundary where the sun can behave in the extreme patterns of polar day and night. The other options are at different latitudes: the Equator is 0°, the Tropic of Cancer is around 23.5°N, and the Antarctic Circle is around 66.5°S.
