Q77 (CAPF/2026) Geography › World Physical Geography

Consider the following statements :
1. A great circle is the largest possible circle that can be drawn on the surface of the sphere.
2. Every great circle divides the Earth into equal halves.
Which of the statements given above is/are correct?

Result
Your answer:  ·  Correct: C

Explanation

Both statements are correct based on the geometric principles of a sphere:

  • Statement 1: A great circle is any circle on the surface of a sphere whose plane passes through the center of that sphere. Because its diameter is equal to the diameter of the sphere, it is the largest possible circle that can be drawn on its surface.
  • Statement 2: Since the plane of every great circle passes through the center of the sphere, it naturally bisects the sphere into two equal halves, known as hemispheres.

On Earth, the Equator is the most prominent great circle. While all meridians (lines of longitude) paired with their opposite meridian form great circles, parallels of latitude (except the Equator) are "small circles" because their planes do not pass through the Earth's center.
