The equator is a line of latitude that is a great circle. As you move in the direction of either the north pole or the south pole, away from the equator, you are then drawing a circle around only a fraction of the planet, rather than the full circumference. The lines of latitude get progressively smaller, until at the poles they collapse into mere points.
The equator .
The equator (zero latitude) is the only one.
Yes
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.
That question is a ture statement. whew
The reason is because it is in the middle of the earth so it makes the biggest, most round circle, (around the Earth). it has the farthest to go around thus creating a perfectly round circle of latitude around Earth........................(i'm 13)
Meridians converge at the poles and intersect the equator at 90 degrees. They are all great circle lines called lines of longitude. The equator is a line of latitude and the only line of latitude that is a great circle line. As you move away from the equator the lines of latitude describe smaller and smaller circles round the planet as you approach the poles.
The equator is the only parallel of latitude that's a great circle.In fact, it's the only locus of any constant coordinate that's a great circle,since the meridians of longitude are all semi-circles.
Only one line of latitude is a great circle ... the equator. Meridians of longitude are semi-great-circle, but we hardly ever use that term for longitude lines. "Great Circle" is a misnomer. It is actually the shortest straight line between two points on the surface of the spherical Earth. However, when plotted on a flat paper map (which is subject to considerable distortion) the path looks curved. But it's the MAP that is distorted; the path is straight.
There is only 1 major line of latitude that goes pass Europe, and that is the Arctic Circle.
The equator is at 0 degrees latitude, which means it is the line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. It is the widest part of Earth's surface, and the only line of latitude that is a great circle.
No. Any great circle on the earth has a circumference of about 24,000 miles. The circumference of the Arctic Circle (and the Antarctic circle too) is about 9,945 miles. Imagine circles around the North Pole. The closer to the pole the circle is, the smaller it is. If you were right there at the North Pole, you could walk a 10-foot circle around it. The Arctic Circle is a circle around the pole, but about 1,570 miles south of it. The only circle around the pole that's a great circle is the Equator.
