Longitude lines. They are also called meridians.
The equator......:) right?
Longitude measures the distance east and west of the prime meridian.
Distance East or West of the prime meridian is measured in degrees of longitude.
The Prime Meridian -- and its opposite, the International Date Line -- are lines of Longitude called meridians. There are 360 whole-numbered meridians on earth, divided into 1…80-degree halves, represented by the two meridians described, above. Distances east and west of those lines are measured in degrees (60), minutes (60) and seconds (60). Because the Earth is round, the mileage between meridians can be different at different latitudes. The differences range from between zero kilometers at the poles to 111.320 Km at the Equator. (At either pole, you can walk around the pole, and essentially walk around the earth by passing through all the lines of Longitude on earth.) You can calculate the length of a degree based on latitude, using the reference material, below.
All of the other meridians; the lines of longitude.
the lines of latitude.
The lines of longitude measure degrees east and west of the prime meridian, but they don't directly measure distance. The lines of longitude all converge at both poles, and ar…e farthest apart from one another at the equator. This is unlike the lines of latitude no two of which ever touch because they are circles that are parallel to one another with their centers located on the earth's axis. You can calculate distance between degrees of longitude, but you need to know the degrees latitude in order to do that.
Longitud is used to measure the distance of east and west from the prime meridian
The lines east and west of the Prime Meridian are called lines of longitude.
longtitude and latitude are the lines used to pin point your location on the globe, are these the lines you are refering to?
Any lines on a map or globe that join the north and south poles indicate angles of longitude east or west of the Prime Meridian.
The Prime Meridian is defined as zero degrees of longitude. The distance in miles between degrees of longitude depends on thelatitude; one degree of longitude equals the cosi…ne of the latitude* 60 nautical miles. Note: If you're using Excel or some other spreadsheet program, besure to convert degrees into radians before calculating the cosineof the latitude.
Lines of longitude pass from pole to pole, and the Prime Meridian passes through the Greenwich Observatory. London, UK, and is zero.
