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}
What else can I help you with?
What is the name of the line on the map that circles the middle of the earth?

What is the parallel line that circles the earth?
The parallel line that circles the Earth is the Equator. It is an imaginary line located at 0 degrees latitude that divides the Earth into the Northern Hemisphere and Southern Hemisphere.
What is the nam of the imaginary line that divides the earth into the northe and southern hemisphere?
The imaginary line that divides the Earth into the northern and southern hemispheres is called the Equator. It is located at 0 degrees latitude and circles the Earth horizontally.
Halfway between the north and south poles what circles the globe at 0 degrees?
The equator is a line of latitude that circles the Earth at 0 degrees. It is halfway between the North and South Poles, dividing the Earth into the Northern and Southern Hemispheres.
What is the imaginary line dividing the northern portion of the globe from the southern?
The imaginary line dividing the northern portion of the globe from the southern is called the Equator. It is located at 0 degrees latitude and circles the Earth horizontally.
Why are the equator and all lines of longitude called great circles?
The equator and all lines of longitude are called great circles because the represent the circumference of the earth. The other latitude lines along the globe are smaller then the actually circumference.
Which parallel of latitude are great circles?
All parallels of latitude, except for the Equator, are not great circles. Great circles are the largest circles that can be drawn on a sphere and pass through its center, whereas small circles do not pass through the center of the sphere.
Why diametrically opposite lines of longitude and equator are called great circles?
A 'great circle' is any circle on the surface of a sphere that has its center at the center of the sphere. The equator is the only parallel of latitude that's a great circle. Every meridian of constant longitude is a semi-circle, and together with the one directly opposite it, they form a great circle. The shortest distance between two points on a sphere is the piece of the great circle through them.
Why is a great circle used for navigation?
Because any 'Great Circle' is the shortest distance across a sphere. Where the Earth is concerned , all the meridians and the Equator are Great Circles. The Plane of a 'Great Circles ' 'cut' the sphere into two equally sized hemispheres. NB Other than the Equator all the latitudes are NOT great Circles.
Is the Tropic of Cancer a great circle?
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.
Are all parallels great circles?
No, not all parallels are great circles. A great circle is the largest possible circle that can be drawn on a sphere, and it divides the sphere into two equal hemispheres. Parallels, or lines of latitude, are circles that run parallel to the equator, and only the equator itself is a great circle. Other parallels, such as those near the poles, are smaller circles and do not divide the sphere into equal halves.
What is the name given to the imaginary line that circles the middel?
The imaginary line that circles the middle of the earth is called the equator.
Which parallels are not circles?
a cylinder
What lines of latitude are great circles?
180* glad to help I think it's the equator. not the answer above.
When you move away from the equator where do meridians go?
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.
What do we call the imaginary line that circles the Earth's middle?
The horizontal line that goes around the "waist" of the Earth is the Equator. The vertical line that goes vertically around the Earth, through the poles, is the Prime Meridian.
Why is the equator the only parallel that is a great circle?
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.
