The equator (zero latitude) is the only one.
Arctic Circle.
The line of zero latitude, also known as the "equator", is.It's roughly 24,800 miles long.
Yes,and it is included from the lines of latitude:tropic of cancer,equator,tropic of capricorn & antarctic circle
In geometry it is called the "Great Circle".
Any such line is called a great circle. There are infinitely many of them.
The equator .
Yes
The great circle at 0 degrees latitude is known as the Equator. It is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
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 Arctic Circle is a line of latitude. As of 2012, it is approximately 66° 33' 44" N latitude.
True. The equator is the only line of latitude that is a great circle because it lies in a plane that divides the Earth into two equal halves. Other lines of latitude are smaller circles.
The equator is the only line of latitude that is a great circle because it is the only line that divides the Earth into two equal halves. A great circle is the largest circle that can be drawn on a sphere, and the equator meets this criteria by encircling the Earth's widest point.
it is a latitude
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.
-- Since every point on a line of latitude has the same latitude, the line has no thickness. -- Its length depends on its latitude. -- The line at zero latitude, known as the 'equator', is a great circle and so its length is the circumference of the Earth ... about 24,900 miles. -- Every other line of latitude is a small circle. Its length is 24,900 miles times the cosine of the latitude which it marks. -- The distance between any latitude and the one that's 1° north or south of it is about 111.1 kilometers (69 miles).
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 Arctic Circle is a line of latitude. It has no temperature.
