By vertical lines, like meridians, but not always straight.
meridian means the north pole to the south pole and longitude meridians on the map are west.
lines of equal longitude, a.k.a. meridians
Meridians are not parallel. They join at the poles. Parallels of latitude is a common phrase. Meridians of longitude look parallel on the the map, but they're not on the globe.
It is the Mercator.
Meridians on a globe get closer and eventually merge at the North and South Poles. On a map (a flat plane) the meridians are drawn parallel and there is distortion at the poles, most noticeable on a world map.
Name the two meridians east of the meridian on this map.
On a Mercator map the Meridians (vertical lines of Latitude) are straight lines at right angles to the lines of Longitude.

its a line that separates the the world in the world on a map or globe too
Meridians are not parallel. Apart from that, what is the question?
The "cylindrical projection" map. See bottom of http://www.progonos.com/furuti/MapProj/Normal/ProjCyl/projCyl.html .
Those are meridians of constant longitude.
Meridians - or lines of longitude.
Are you thinking og the meridians? The meridians are the lines you see on a map that conects the north and south pole and also those who determ longtitude
