Slight problem there: those are latitudes, not longitudes!
The major longitude is the Greenwich meridian. The other is the line of longitude on the opposite side of the earth - more or less the International Date Line. Except that it is not a straight pole-to-pole line.
The prime meridian.
The poles.
These invisible lines that circle the earth and are vertical or running north to south are longitude or meridian lines. These lines are also perpendicular to lines called latitudes that are parallel to the equator.
lines of longitude are lines drawn north and south and measure east and west a famous line of longitude is the Prime meridian
The highest longitude lines are the prime meridian at 0 degrees longitude and the 180 degrees longitude line. These lines mark the starting point for longitude measurements to the east and west, respectively.
=no=
The prime meridian.
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 poles.
There are more than one major lines of longitude that pass through the Argentine. They have values around 58 degrees west but none of the lines/meridians is a named line.
These invisible lines that circle the earth and are vertical or running north to south are longitude or meridian lines. These lines are also perpendicular to lines called latitudes that are parallel to the equator.
meridians or lines of longitude
"Lines" of constant longitude are "meridians".
Lines of longitude, or meridians.
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.
Parallel lines, by definition, cannot meet. The lines of longitude meet at the Poles.
