Question

What is meridians of longtitude ??.​..​

Answer 1

A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.

Each meridian is perpendicular to all circles of latitude. Each is also the same length, being half of a great circle on the Earth's surface and therefore measuring 20,003.93 km.

Meridians connect the North Pole to the South poles by a set of imaginary lines, and perpendicular with each parallels of latitude. The length of 1º of longitude varies with varying latitude. At the Equator, they are the same length as a degree of latitude, but decrease polewards.

The meridians from West of Greenwich (0°) to the antimeridian (180°) define the Western Hemisphereand the meridians from East of Greenwich (0°) to the antimeridian (180°) define the Eastern Hemisphere.

ANSWER✍

⭐The imaginary line which join all the places having some angular distance east and west of the prime meridians is known as line of longtitude. these are also called meridian becoz all the places located along the particular longtitude face the over head sun at the sun time.⭐
