Q. Consider the following statements:

1. All meridians are of equal length.
2. The length of each meridian is approximately 20,000 kilometres.

Which of the statements given above is / are correct?
Answer: Both 1 and 2
Notes: All meridians are equal in length, each representing half of a great circle on Earth’s surface. Their individual length is approximately 20,003.93 km, thus making statement 2 correct. These characteristics contrast with parallels of latitude, which vary in length. Both statements are therefore accurate according to standard geographical knowledge.
