what are Meridians of longitude?
In short
Meridians of Longitude : The meridians of longitude refer to the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian. Lines of longitude are often referred to as meridians.
In long
Parallels of latitude are the circles which are parallels from the equator to the poles whereas the lines of reference running from the North Pole to the South Pole are called meridians of longitude.
Latitude and Longitudes are measured in degrees and each degree is subdivided into 60 minutes which is denoted as (‘) and each minute is subdivided into 60 seconds which is denoted as (“).
The equator has zero degrees latitude and its distance from the equator to poles is one-fourth of a circle round the earth. It is measured as 1/4th of 360 degrees which is 90 degrees.Through this we can find that 90 degrees towards north latitude marks the North Pole and (0 degrees towards south latitude marks the South Pole.
In terms of Longitude, the time which we are able to count is on the basis of Greenwich mean time. The meridian which passes through Greenwich is also known as Prime Meridian.
Earth is divided into the Northern Hemisphere and Southern Hemisphere as the Equator lies in between whereas the prime meridian divides into Western and Eastern Hemisphere.
Answer:
Meridians of longitude is an imaginary line between earth's surface extending from north to south.
