The northern and southern hemispheres each have 360 degrees of longitude.
The eastern and western hemispheres each have 180 degrees of longitude.
You can use as many or as few 'lines' as you want, to mark off any number of degrees.
equator and hemisphere
one degree, about 111 kilometers at the equator.
Lines of latitude measure the distance north or south of the equator, dividing the Earth into Northern and Southern Hemispheres. Lines of longitude measure the distance east or west of the Prime Meridian, dividing the Earth into Eastern and Western Hemispheres. By using the intersection of these lines, we can determine which hemisphere a place is located in.
The prime meridian (0 degrees longitude) and the 180th meridian both divide the eastern and western hemispheres.
there are ninety lines in each hemisphere There are 90 degrees of latitude in the northern Hemisphere, and another 90 in the southern one. There are 180 degrees of longitude in the eastern Hemisphere, and another 180 in the western one. In each hemisphere, you're free to draw as few or as many lines in that range of numbers as you want to see. There's no standard set of 'lines' that everybody must use. Some maps and globes have more lines on them, some have fewer, some don't have any at all. Would you go into the hardware store and ask the man "How many lines are there on the tape measure ?" ?
The Prime Meridian, which is 0 degress longitude.
It is known as the Eastern Hemisphere, with lines of longitude easterly from the Prime Meridian (zero longitude) to the Datum Line of 180 degrees longitude. In the opposite direction from the Prime Meridian is the Western Hemisphere. To the north of the Equator is the Northern Hemisphere, and to the south of the Equator is the Southern Hemisphere.
Locations in the western hemisphere are described with a range of 180 degrees of"west longitude" ... exactly what you'd expect for 1/2 of a sphere. Within that range,you're free to draw as few or as many 'lines' on your map as you feel you need.
5 or 6 lines of longitude
The Prime Meridian and the Internation Date Line
360 lines i think... There are 12 lines of East longitude. 360 is WAY off.
East longitude puts it in the Eastern Hemisphere. West longitude puts it in the Western Hemisphere.
