Why is the zero degree longitude known as the Prime Meridian while others are simply meridians?

All other meridians are defined by their angular distance (from 0 to 180 degrees) from the arbitrary "prime" meridian. Half are measured east and the other half measured west, so that 180 degrees east is the same line as 180 degrees west (which is where the International Date Line is centered).

What is the total number of meridians on the globe?
meredians on a globe are number starting with prime meridian at greenwich which is marked as 0.meridians are drawn at an interval of 1.there are 180 meridians towards the east and 180 towards the west of the prime meridian.the meridian which are towards the east are marked as e and the meridians towards the west are marked as w.thus there are 360 meridians
What is the distance between meridians in degrees?
360
Which one line is parallel latitude or longitude?
All 'lines' of latitude are parallel to all others.No meridian of longitude is parallel to any others.-- All 'lines' of latitude are parallel to all others.-- No meridian of longitude is parallel to any other one.
Can the equator be called meridian?
No. The equator is a parallel of latitude, and likeall of the others, it crosses all of the meridians.
What are facts about meridian?
They are also called Lines of LongitudeThey measure the angles east or west of the prime meridianThey run from the North Pole to the South PoleEvery meridian of longitude is the same length -- 1/2 of the Earth's polar circumference, roughly 12,410 miles.All meridians of longitude meet at the north pole and at the south pole.Every meridian of longitude crosses some part of Antarctica.The key meridians are the Prime Meridian at 0 degrees and the 180th meridian (or anti-meridian) which is at 180 degrees east or west of the Prime Meridian.The 'anti-meridian' is at both -180 degrees and +180 degrees on the map which is the same imaginary line where the east and west hemispheres meet. It joins the north and south poles, and runs through the Pacific Ocean.
What meridian of longitude is closet to Galway?
The intersection of Merchants Road Lower and The Long Walk, at the south corner of the Galway City Museum, is located at 53.2695° north latitude 9.0535° west longitude. The meridian of longitude that passes through that point is the meridian of 9.0535° West. There is not some finite set of meridians that everyone must use and no others. A meridian can be defined at any longitude.
What lines run north and south through the poles and measure distance east or west of the prime meridian?
If one of them is the "prime" meridian, what do you suppose the others might be called? If you guessed "meridians", you win.
What is the reference line when determining the longitude?
The Prime Meridian is the reference line. That's the meridian of longitude that joins the north and south poles and passes through a mark on the floor of the transit room of the Royal Observatory at Greenwich, a suburb of London. By international agreement, that line is zero longitude. All others are measured east or west from it, from zero to 180°.
What lines run parallel to longitude?
No. Meridians of constant longitude are semicircles that join the north and south poles. Every one of them crosses the equator.
What is the odd one out from antarctic circle tropic of capricom and prime merdian?
The Prime Meridian is not like the others. It's a meridian of longitude, whereas the other two are both parallels of latitude.
Why are lines of latitude and longitude called great circles?
They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.
What is the line when determining the longitude?
The Prime Meridian is the reference line. That's the meridian of longitude that joins the north and south poles and passes through a mark on the floor of the transit room of the Royal Observatory at Greenwich, a suburb of London. By international agreement, that line is zero longitude. All others are measured east or west from it, from zero to 180°.
