It is a circle because, the earth is a circle, and the equator stretches all the way around the earth.
Great circle or circle
eQuator forms a great circle because it is a circle created by the intersection of a sphere and a plane that passes through the center of the sphere. The equator of the Earth, for example, is a great circle because it divides the Earth into two equal halves. The shortest path between any two points on a great circle is along the circle itself.
The equator .
No; neither of the tropics is a great circle. The only line of latitude that is a great circle is the equator. The arctic and antarctic circles are not great circles, either.
The reason they call the equator the great circle is because circles the whole earth in the middle.becase its the only line that runs in the centre of the earth and goes right arround . {nickstar}
Yes
Any great circle (the best known great circle is the equator) which are about 24,901 miles long.
The equator is the only parallel that is a great circle because it is centered on the Earth's axis of rotation. This means that it divides the Earth into two equal hemispheres and its circumference is the maximum possible for a circle on the Earth's surface. Other parallels are smaller circles and not great circles.

The Equator
equator
No, the Tropic of Cancer is not an example of a great circle. It is a circle of latitude located at approximately 23.5 degrees north of the equator, which means it is parallel to the equator and does not divide the Earth into two equal halves. Great circles, such as the equator and lines of longitude, represent the shortest distance between two points on the surface of a sphere.
