No.
You have to cross 360 degrees of meridian for a great circle, so 180 degrees East plus 180 degrees West around the equator will form a great circle.

Why are lines of latitude and longitude called great circles?
They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.
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.
How does eQuator form a great 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.
Is the word greatly a preposition?
No, it is an adverb. It is the adverb form of the adjective great and means "to a great extent" or degree.
Is the equator the only meridian that is a great circle?
The equator is a great circle. Meridians of longitude that cross over the north and south poles are also great circles. For every location on a great circle, it's antipodal location is also on the circle. Other than the equator itself, any great circle crosses the equator at two antipodal locations, 180° apart. Other than the equator and meridians of longitude that run due north and south, any great circle reaches it's maximum latitudes at two locations that are 90° of longitude east and west of the two locations where the great circle crosses the equator.Yes, since the intersecting plane that hypothetically forms the equator would cut through the center of the sphere.
What two lines that form a 90 degree angle?
line that goes east and a line that goes north
Is arctic circle 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.
What combined with the prime meridian makes a complete circle around the earth?
The Prime Meridian and the meridian of 180° longitude combine to form a great circle on the Earth. Each of them alone is a semi-circle.
Is slightly an adverb?
Yes it is. It is the adverb form of the adjective "slight" and means not to any great degree.
If you have 6 boards and want to make a complete circle What degree do you cut each end of the boards?
If you cut all six boards at 60 degree angles, you can create a hexagon, which is analogous to a circular form.
Which line corresponds to 180 longitude?
According to experts, the line that corresponds to the 180 degree longitude is the 180th meridian. The meridian and longitude work together to form a 360 degree circle.
How do the prime meridian and the equator form a grid?
They don't. All you have there is one great circle and one great semi-circle, on the same spherical surface, that are perpendicular where they intersect. If you want a grid, you'll have to find an old 6L6GB or a 12AT7 somewhere.
