Concept:A great circle is formed when a plane cuts through the centre of the Earth, dividing the Earth into two equal halves.
Explanation:The Equator is the only line of latitude that is a great circle.
Lines of longitude are paired with their opposite meridians to form great circles.
For example, the Greenwich Meridian (
0∘) and the International Date Line (
180∘) together form one great circle.
They are lines of longitude, not lines of latitude.
Therefore, calling them “lines of latitude” is incorrect.
A great circle divides the Earth into two equal spheres or hemispheres.
The centre of any great circle is also the centre of the Earth.
These statements make options A, C, and D correct.
Only option B contains a false statement.
Answer:B. The Greenwich Meridian and the International Date Line are the only lines of latitude forming a Great Circle.
