There is no single meridian of longitude that divides the earth in half. Each meridian
is a semi-circle drawn between the north and south poles.
However, if you take any meridian and join it to the one marking the longitude exactly
180 degrees away from the first one, then together they form a circle that divides the
surface of the earth in half.
The zero longitude meridian line runs through Greenwich, England, and is described as GMT ( Greenwich Meridian Time ) or Zulu Time ( military ).
The prime meridian is a line of longitude
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
The divisions of longitude are measured in degrees. The Earth is divided into 360 degrees of longitude, with the Prime Meridian (0 degrees longitude) serving as the starting point. Longitudes range from 0 degrees to 180 degrees east or west of the Prime Meridian, with 180 degrees being the International Date Line.
Latitude is an angle measured north or south from the equator. Longitude is an angle measured east or west from the Prime Meridian
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.

prime meridian
The Prime Meridian is a line of longitude that passes through Greenwich, England, and is used as the starting point for measuring longitude around the world.
Zero degrees longitude is the prime meridian, the line of longitude that passes through Greenwich, England.
The 0 longitude line, or the Greenwich Meridian, is GMT 0, which means all time zones branch out from there. It is the somewhat the 'center' of the Earth's time.
equator
The divisions of longitude are measured in degrees. The Earth is divided into 360 degrees of longitude, with the Prime Meridian (0 degrees longitude) serving as the starting point. Longitudes range from 0 degrees to 180 degrees east or west of the Prime Meridian, with 180 degrees being the International Date Line.
Yes it is. It is the starting point to measure degrees East or West.
The Prime Meridian is found at 0 degrees longitude. Additionally, this is the longitude line that goes through Greenwich, England which marks the base time zone GMT or UTC that other time zones are relative to.
