Question 1544Navigation General

The correct answer is B) Arctic Circle. The parallel of latitude at 66°33'N marks the Arctic Circle, which is the northernmost of the five major circles of latitude on Earth. The Arctic Circle is the southernmost latitude at which the sun can be seen above the horizon for 24 continuous hours during the summer solstice and below the horizon for 24 continuous hours during the winter solstice. The other options are incorrect because the Tropic of Cancer (A) is at 23°26'N, the Tropic of Capricorn (C) is at 23°26'S, and the ecliptic (D) is the apparent path of the sun across the sky over the course of a year, not a parallel of latitude.
