The so-called 'lines' of longitude are also called 'meridians'.
The Prime Meridian is a line of longitude. It's the line made out of
all the points on Earth whose longitude is zero.
The Prime Meridian is a line of longitude. It's the line made up of every point on earth whose longitude is zero.
Prime meridian, from which longitude is measured both east and west, is the main line of longitude.
The longitude of every point on the Prime Meridian is Zero.
The Prime Meridian is a longitude line, made up of all the points that have zero longitude and every latitude.
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
The starting line for measuring latitude is the Equator (0 degrees latitude), while the starting line for measuring longitude is the Prime Meridian (0 degrees longitude), which runs through Greenwich, England.

Just as the equator is 0° latitude, the Greenwich Meridian, or Prime Meridian, is 0° longitude. It is the origin from which all longitudes are measured.
The Prime Meridian is made out of all the points at zero longitude and every latitude.
The Prime Meridian is at zero degrees longitude and every possible latitude.
Parallels (latitude) are measured in degrees north or south of the equator, with 0 degrees being the equator. Meridians (longitude) are measured in degrees east or west of the Prime Meridian, with 0 degrees being the Prime Meridian which runs through Greenwich, England. Longitude and latitude are used to define specific locations on Earth's surface.
