What is the difference between a prime meridian and a meridian?
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.
Why is greenwich the centre of time?
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.
What is on the intersection of the Prime Meridian and the International Date Line?
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.
Why is London on the Prime Meridian?
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.
What is the significance of 0 degree longitude or prime meridian?
It is simply an agreed upon reference point. It is arbitrary, and in the past each country defined its own. French sailors, for example, used a prime meridian that ran through Paris. Great Britain's dominance of the seas is probably the reason that the Greenwich Meridian came to be so widely accepted as the standard reference.
Which continent is divided in half by the prime meridian?
The Prime Meridian effectively divides the continent of Antarctica in half. Since prime meridians are arbitrary this is based on the Greenwich Prime Meridian.

What are the lines that run north and south on a globe?
The lines that run north and south on a globe are called meridians of longitude. They converge at the poles, with the Prime Meridian (0 degrees) serving as the reference point for measuring east and west.
What is on the intersection of the Prime Meridian and the International Date Line?
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.
What imaginary line splits the earth into east and west hemispheres?
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.
Why is the prime meridian called a arbitrary line?
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.
What is the northern hemisphere?
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).
What is a sentence for Arbitrary?
These are our output. But it is Arbitrary.
What is the place name associated with the prime meridian?
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.

What is Prime meridan?
The Prime Meridian is themeridian (line of longitude) at which longitude is defined to be 0°.The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the International Date Line generally follows, form a 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 passes through the Royal Observatory, Greenwich, in east London, United Kingdom, known as the International Meridian or Greenwich Meridian.Historically, various meridians have been used, including four different ones through Greenwich.By.
