Question

Give a reason for the following:

Lines of longitude are also called Meridians of longitude?

Answer 1

The word ‘meridian’ means related to noon or 12 p.m. As every longitude receives the noontime or 12 p.m. at different intervals where the sun’s rays are exactly vertical over a particular longitude. On a particular longitude, the noon-time is the same from north to south; so a longitude is also called a Meridians of longitude.
