There is no begining or end. It is a line that goes on forever passing thru the north and south poles.
The origin of longitude is the Prime Meridian, an imaginary line joining the north and south poles and passing through the Royal Observatory in Greenwich, England.
Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.
Ware the main properties of parallels and meridians
There are an infinite number of meridians. 360 of them are multiples of a whole degree because there are 360 degrees in a circle.
72 number of meridians can be drawn on the globe at 5 degree interval
they appear as straight lines.i needed help w this (?] too shoooot.aha,
The Prime Meridian is numbered zero degrees. Meridians, or lines of longitude, are numbered with increasing numbers of degrees both east and west of the Prime Meridian. On the opposite side of the world from the Prime Meridian is 90 degrees, which is also the International Date Line.
I am not sure, but i think it is the prime meridian, pretty sure i am not right
They are numbered in degrees and fractions of degrees. Parallels also known as latitudes are measured north and south of the equator up to a maximum of 90 degrees north or south. Meridians or longitudes are measured east and west from the prime meridian which passes through Greenwich in London, up to 180 degrees.
Qi travels through the body along channels called meridians. There are 12 main meridians, corresponding to the 12 principal organs as defined by the traditional Chinese system
meridians meet at the poles
Of the twelve regular meridians, the yin meridians always flow up the body, and all the yang meridians always flow down.
23 meridians, dividing earth into 24 time zones
Chromosomes are numbered using a system called the International System for Cytogenetic Nomenclature (ISCN). The number on each region of the chromosome increases as the distance from the centromere to the telomere increases.
The 'parallels' of latitude are numbered in degrees north or south of the equator, from zero to 90 degrees. The equator is zero; the poles are 90 degrees north/south. The meridians of longitude all pass through the poles. They're numbered in degrees east or west of the Prime Meridian, from zero to 180 degrees. The Prime Meridian ... the line defined as zero longitude ... is the meridian that joins the north and south poles and passes through Greenwich, England. (That's the origin of the terms "near east", "middle east", and "far east" ... they're the regions that are near, medium, and far to the east, beginning in England at the prime meridian.)

FM 21-11 is numbered in the old system. FM 4-25.11 is numbered in the new system. The book is the same.
