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.
There are an infinite number of meridians ... one at every possible longitude that
you can think of or name ... but only one Prime Meridian ... at zero longitude.

-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.

differences between equator and prime meridian
The difference between the east and the west hemisphere is one is on the west side of the Prime Meridian and the other is on the eastern side of the Prime Meridian.
Prime Meridien is also called Greenwich Meridien. They are not different.

Nominally 180° of longitude, or halfway around the Earth.
