One. Longitude is derived from the Prime Meridian. Values are measured in relation to this Prime Meridian as East or West longitude. If you withdraw this constant, Prime, then values are given in Positive, Zero, and Negative.
The distance between degree's of longitude are also not exact from top to bottom. At the equator they are approx. 69 miles wide, as you go toward the poles they become smaller, with an example being at a Latitude of 45 degree's a degree of longitude is approx: 49miles wide.
These can also be more specific in Minutes and Seconds.

The line measuring 0 degrees longitude is also called what?
prime meridian
What is longitude means?
longitude: distance east or west on the earth's surface, measured in degrees from a certain meridian. (line from the North to the South Pole.)Or you can check out this website it has a lot on geography:See related link below
The line of longitude used as the origin in the system of coordinates?
The meridian of longitude passing over Greenwich, England.
What is an fact about the Greenwich Observatory?
it is located on the 0 degree longitude line
How many degrees is at the international date line?
Most of it is at 180 degrees.
How many degrees differences is there between each line of laditude and longitude?
10 degrees.
Where are lines of longitude farthest apart?
Lines of longitude are farthest apart where they intersect the line of the equator.
Does 90 degrees west longitude have a name?
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
The line of longitude that is zero degrees longitude is the?
prime meridian :/
Is the prime meridian a line of latitude or a line of longitude?
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
What is the degree of difference between each line of latitude and longitude?
Firstly, different maps or atlases draw lines of latitude and longitude in varying degrees apart. Although most maps have differences of 10 degrees apart, atlases can be as close as 1 or 2 degrees. Secondly, you might be referring to the major lines of latitude and longitude, such as the Equator and the Prime Meridian. Some maps that are very small only show the major lines of latitude and longitude. The difference between the equator and the Tropics of Cancer and Capricorn is 23.5 degrees, while the difference between the equator and the Arctic and Antarctic Circles is 66.5 degrees. The difference between the Prime Meridian and the International Date Line is 180 degrees.
What longitude is 59 degrees west of International Date line?
121 degrees east longitude
What degrees of longitude is the international date line on?
Whether travelling to the West or to the East from the Prime Meridian (zero Longitude) the International Date Line is 180 degrees Longitude.
What would be the line of longitude for a place that is west of the prime meridianhalfway between the prime meridian and the180 degrees line of longitude?
90 degrees 40 degrees and 90 degrees
Which line of longitude is found opposite of the Prime Meridian?
The major line of longitude located at 180 degrees longitude is the International Date Line.
Three countries 100 degrees W line of longitude?
Each of the following has territory at 100° west longitude: -- Canada -- USA -- Mexico -- Antarctica
What longitude line is the prime meridian located?
0 degrees longitude.
