It is the Prime Meridian
They are called the lines of longitude. Lines of longitude range from 0 degrees on the prime meridian to 180 degrees.
They are called the lines of longitude. Lines of longitude range from 0 degrees on the prime meridian to 180 degrees.
The Equator witch is 0 degrees latitude and longitude
The imaginary line running through Greenwich, England at 0 degrees longitude is called the Prime Meridian. It marks the starting point for measuring longitude and defines the Eastern and Western Hemispheres.
"Prime Meridian" if you're talking longitude, or "Equator" if you're talking latitude.
The imaginary line at 0 degrees latitude is called the equator.
Such a line is called a line of longitude and in special cases a meridian (e.g. the Greenwich meridian which is 0degrees longitude)
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
It is the "Prime Meridian" or the "0 degree Meridian" which is the basis for calculating time in most of the world.
The Equator.
The imaginary line that runs north and south from the North Pole to the South Pole at 0 degrees longitude is called the Prime Meridian.
