What is Prime Meridian short answer?
The prime meridian is the line drawn north to south at 0° (0 degrees) longitude. Credits: NASA. an imaginary line on Earth that passes north to south through the Greenwich Observatory in London, England. Sentences: The prime meridian divides Earth into the Eastern Hemisphere and the Western Hemisphere.
What is the prime meridian and its purpose?
The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Any line of longitude (a meridian) can serve as the 0 longitude line.
What is the definition of prime meridian for kids?
The prime meridian is the imaginary line that divides Earth into two equal parts: the Eastern Hemisphere and the Western Hemisphere. The prime meridian is also used as the basis for the world’s time zones. The prime meridian appears on maps and globes. It is the starting point for the measuring system called longitude.
Why is it called the Prime Meridian?
In 1884, the International Meridian Conference took place in Washington, D.C. to establish an internationally recognised single meridian. The meridian chosen was that which passed through the Airy transit circle at Greenwich, and it became the prime meridian of the world.
How many prime meridians are there?
Longitudes for the Earth and Moon are measured from their prime meridian at 0° to 180° east and to 180° west. For all other Solar System bodies, longitude is measured from 0° (their prime meridian) to 360°. West longitudes are used if the rotation of the body is direct, that is, it follows the right hand rule.
What is the another name of prime meridian?
The prime meridian is the planet’s line of zero degrees longitude. Sometimes called the Greenwich Meridian or the International Meridian, Earth’s prime meridian crosses the original site of the Royal Observatory in Greenwich, England.
Which countries does the Prime Meridian pass through?
On its path from pole to pole, the Meridian passes through England, France, Spain, Algeria, Mali, Burkina Faso, Togo, Ghana and Antarctica.
What are 3 facts about meridians?
Facts about Lines of Longitude–Are known as meridians. –Run in a north-south direction. –Measure distance east or west of the prime meridian. –Are farthest apart at the equator and meet at the poles.
What is the opposite of prime meridian?
The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres.
What is an example of prime meridian?
The prime meridian is a reference line through Greenwich, England that measures longitude east and west. An example of prime meridian is zero degrees longitude. The meridian from which longitude is measured both east and west; 0° longitude: it passes through Greenwich, England.
What is the difference between prime meridian and standard 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 did the Greenwich Meridian move?
In order for the plane of the geodetic prime meridian to pass through the geocenter, its trace on the ground in the vicinity of Greenwich must move to the east by about 102 m, the sign and magnitude of which is correctly predicted by EGM2008.
