Q. Which of the following latitude is almost half of length of equator?
Answer: 60th Parallel North or South
Notes: Besides the equator (0°), the North Pole (90°N) and the South Pole (90° S), there are four important parallels of latitudes- (i) Tropic of Cancer (23½° N) in the Northern Hemisphere. (ii) Tropic of Capricorn (23½° S) in the Southern Hemisphere. (iii) Arctic Circle at 66½° north of the equator. (iv) Antarctic Circle at 66½° south of the equator. Note: The 60th parallel north or south is half as long as the Equator (disregarding Earth's minor flattening by 0.335%).
