Quizplus · Accepted Answer

The Earth's equator is a great circle because it is a circle on the surface of a sphere that has the same diameter as the sphere. A great circle divides a sphere into two equal parts, and the equator is the largest great circle on the Earth's surface. A small circle is a circle that does not divide a sphere into two equal parts. The Prime Meridian is a line of longitude that passes through the Royal Observatory in Greenwich, England, and a line of equal longitude is a line that connects all the points on the Earth's surface that have the same longitude.
