Quizplus · Accepted Answer

A great circle is the intersection of a sphere and a plane that passes through the center of the sphere. The equator is a great circle because it passes through the center of the Earth and divides it into two equal hemispheres. The Tropic of Capricorn, Tropic of Cancer, Arctic Circle, and Antarctic Circle are all circles of latitude but they are not great circles because they do not pass through the center of the Earth.
