An arbitrary meridian is an imaginary line running from the North Pole to the South Pole that is chosen as the starting point for measuring longitude on a map or globe. It helps establish a reference point for determining the east-west position of a location on Earth.
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.
It was an arbitrary decision to locate the Prime Meridian at Greenwich because that is the location of the Royal Observatory. Every point on Earth exists on a specific meridian. Any one of them could have been chosen. The decision to use the meridian at Greenwich, England was made during the International Meridian Conference held in 1884 at Washington, DC, USA.
Yes. The prime meridian runs from the North Pole to the South Pole. It establishes the line of 0º longitude. This arbitrary starting point defines locations by their separation in degrees east or west of the prime meridian, up to 180° in either direction.
The Prime Meridian runs through London because it was established by Sir George Airy. The choice of location for a prime meridian is entirely arbitrary, so a British scientist chose a line passing through the astronomical observatory at Greenwich in London.
This is called the Prime meridian, it passes through Greenwich, England.
The Prime Meridian effectively divides the continent of Antarctica in half. Since prime meridians are arbitrary this is based on the Greenwich Prime Meridian.

Because it's not based on any physical characteristic of the Earth ... like the Equator is ... but instead, was made up by people and could have been placed anywhere.
It is all of the Earth's surface north of the equator. The Earth can be divided into northern and southern hemispheres, or into eastern and western hemispheres, which use the arbitrary longitudinal lines (e.g. Prime Meridian).
Yes. The prime meridian runs from the North Pole to the South Pole. It establishes the line of 0º longitude. This arbitrary starting point defines locations by their separation in degrees east or west of the prime meridian, up to 180° in either direction.
The Prime Meridian is the meridian (line of longitude) at which longitude is defined to be 0°. The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the generally follows, form a International date line great circle that divides the Earth into the Eastern and Western Hemispheres. Unlike the parallels of latitude, which are defined by the rotational axis of the Earth (the poles being 90° and the Equator 0°), the Prime Meridian is arbitrary. By international convention, the modern Prime Meridian is one passing through Greenwich, London, United Kingdom, known as the International Meridian or Greenwich Meridian. Historically, various meridians have been used, including four different ones through Greenwich.
The lines on a globe that run north and south are called lines of longitude, or meridians. They measure distance east or west from the arbitrary Prime Meridian or Greenwich Meridian, established as 0° longitude.
These are our output. But it is Arbitrary.
Greenwich, England in the UK. The arbitrary longitudinal line includes the location of the Royal Observatory, and was established as the Prime Meridian in 1884 (adopted by France in 1911). After appearing in charts by Nevil Maskelyne from 1765 to 1811, it was officially adopted by Sir George Airy (Astronomer Royal) in 1851.
