A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.

Thereof, what is geographic meridian and magnetic meridian?

The axis line for the geographical true north/south is called the geographical meridian and the axis line joining the magnetic north/south is called the magnetic meridian. The North Magnetic Pole moves over time due to magnetic changes in the Earth's core.

Furthermore, is Meridian and longitude the same? Latitude is a measure of how far north or south somewhere is from the Equator; longitude is a measure of how far east or west it is from the Prime Meridian. Whilst lines (or parallels) of latitude all run parallel to the Equator, lines (or meridians) of longitude all converge at the Earth's North and South Poles.

One may also ask, what is the use of Meridian?

Meridian, imaginary north–south line on the Earth's surface that connects both geographic poles; it is used to indicate longitude.

What is longitude in geography?

In geography, longitude is the distance on the earth's surface, east or west of a defined meridian, usually the meridian of Greenwich, England (0° Longitude), expressed in angular measurements from 180° West (or -180°) to 180° East. Latitude and longitude can be used together to specify a precise location on the Earth.

Where is the prime meridian located?

The Prime Meridian, as it passes through Greenwich, England, is considered 0 degrees longitude. Because both the equator and the Prime Meridian are imaginary lines, they were both established by mankind at some point in human history.

What is the Prime Meridian?

A prime meridian is the 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.

What is the magnetic meridian?

The magnetic meridian is an equivalent imaginary line connecting the magnetic south and north poles and can be taken as the horizontal component of magnetic force lines along the surface of the earth. Therefore, a compass needle will be parallel to the magnetic meridian.

Why longitudes are called meridians?

Longitudes are known as meridians because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles. Same stands true of the longitudes. All longitudes are great circles which meet at the Poles.

Is the equator a Meridian?


The Equator and Prime Meridian are circles that stretch all the way around the Earth. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.

What is Greenwich meridian and why is it important?

As the prime meridian, the north-south line at Greenwich is used as the reference for all other meridians of longitude, which are numbered east or west of it. The Greenwich meridian also serves as the basis for the world's standard time zone system.

What are the main characteristics of meridians?

The meridians or lines of longitude have the following characteristics: All meridians are of the same length and each one is a semi-circle. If any two opposite meridians are taken together, they form a complete circle, which is a great circle.
