Question

Which latitude is called a great circle?

• A. Equator
• B. $66{\frac{1}{2}}^{o}N$
• C. ${20}^{o}S$
• D. $23{\frac{1}{2}}^{o}S$

Answer 1

The correct option is A Equator

• The Equator is another of the Earth's great circles. If you were to cut into the Earth right on its Equator, you'd have two equal halves: the Northern and Southern Hemispheres.
• The Equator is the only east-west line that is a great circle.
• All other parallels (lines of latitude) get smaller as you get near the poles.
