What is prime meridian and how is it used?

The prime meridian is the imaginary line that divides Earth into two equal parts: the Eastern Hemisphere and the Western Hemisphere.

The Prime Meridian divides the Earth into East/West from the North Pole to the South Pole with an imaginary line along the longitude line of 0°. The Antimeridian, at 180° longitude, connects with the Prime Meridian to form a 3D giant circle all around the Globe, dividing it into Eastern and Western hemispheres.

Which line is known as the prime meridian?

Any line of longitude (a meridian) can serve as the 0 longitude line. However, there is an international agreement that the meridian that runs through Greenwich, England, is considered the official prime meridian. The Greenwich Meridian became the international standard for the prime meridian.

The meridian passing through Greenwich, England, designated as the zero meridian (0°) by an international conference in 1884.

What is prime meridian of India?

Ans: The longitudinal extent of India is 30o. To avoid this confusion a longitude passing through the midpoint of 68o 7′ East (western most longitude) and 97o 25′ East (eastern most longitude) is taken as the standard prime meridian of India (i.e. 82o30′).

Why Greenwich is the prime meridian?

Why does the Prime Meridian run through Greenwich? There were two main reasons for the choice. The decision was based on the argument that by naming Greenwich as Longitude 0º, it would be advantageous to the largest number of people. Therefore the Prime Meridian at Greenwich became the centre of world time.

What is prime meridian and when does it established?

The prime meridian is a geographical reference line that passes through the Royal Observatory, Greenwich, in London, England. It was first established by Sir George Airy in 1851, and by 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps.

What are some characteristics of the prime meridian?

1) Each meridian is half of a great circle. 2) They run in a true north-south direction from connecting the North and South Poles. 3) They are spaced farthest apart at the equator but converges at the poles. 4) Meridians help us to determine standard time.

What are facts about the prime meridian?

A prime meridian is a meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, e.g., Earth, into two hemispheres.

What is the importance of prime meridian?

The prime meridian also helps establish the International Date Line. The Earth’s longitude measures 360, so the halfway point from the prime meridian is the 180 longitude line. The meridian at 180 longitude is commonly known as the International Date Line.
