Question

Which latitude is also called the great circle?
A. Equator
B. Tropic of Cancer
C. Tropic of Capricorn
D. Antarctic circle

Answer 1

Hint:
Great circle is something that divides an object or heavenly body into 2 equal parts. The correct option to be chosen is said to be an imaginary line around the centre of Earth.

Complete solution:
The equator is known as the great circle of the earth and it is situated at zero degree latitude. It is said to be the greatest latitude and parallel as if you move away from the equator all the latitude keeps decreasing.

If you cut Earth along the equator you will keep two equal halves of the earth divided into Northern and Southern parts. The great circle is basically something that divides Earth into two halves and therefore equator is considered to be the great circle of the earth. The earth is the widest at the equator.

The Earth's width at the Equator is around 12,756 kilometers (7,926 miles). At the shafts, the breadth is around 12,714 kilometers (7,900 miles). The Earth's tropical lump is around 43 kilometers (27 miles).

The Tropic of Capricorn is situated at the south of equator and it is a subsolar point at the December solstice. The Tropic of Cancer is situated north of the equator.

The Antarctic Circle is an equal of scope on the Earth at around 66.5 degrees south of the equator. Upon the arrival of the southern summer solstice (around December 22 every year), a spectator on the Antarctic Circle will see the Sun over the skyline for an entire 24 hours.


Hence, the correct answer is option A.

Note:
The Equator is a nonexistent line around the center of the Earth. It is somewhere between the North and South Poles, and partitions the Earth into the Northern and Southern Hemispheres.
