It is a circle because, the earth is a circle, and the equator stretches all the way around the earth.

Which parallel of latitude are great circles?
Only the equator, i.e. the parallel of zero latitude.
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.
What are the three names for the equator?
Well, there is only one equator on Earth and its called the "Equator".
Which parallel of latitude are a great circle?
The parallels themselves are oriented in the east-west direction. They're parallel to one another, as well as to Earth's equator. What "latitude" denotes, however, is how far north or south of the equator you are. If you're located at 1° N, you're about 69 miles north of the equator. If you're at 89° N, you're about 69 miles from the North Pole. I said "about 69 miles" there because it's not exactly 69.000 miles, AND because it varies a tiny bit, due to Earth bulging out a tiny bit at the equator (because it's spinning at 1000 MPH). But don't let anyone tell you Earth is oval, because this bulge is something that we can measure. To look at it, no one would know it wasn't a perfect sphere.
Is the only line of latitude that is a Great Circle is the equator ture or false?
That question is a ture statement. whew

Name the latitude that is truly a great circle?
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.

Is the equator the only line of latitude that is a great circle?
Yes

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.
The prime meridian and the make a complete circle around the earth?
The Prime Meridian and the meridian of 180° longitude combine to forma great circle on the Earth. Each of them alone is a semi-circle.Every parallel of latitude also circles the Earth completely, but among those,only the equator is a great circle.
What line of latitude is a great circle?
The equator (zero latitude) is the only one.

Do meridians get parallel to one another as they get closer to the poles?
no. They are parallel to each other only at the equator. But as soon as you move away from the equator, they are no longer parallel.
