Latitude
Longitude lines.
Longitude measures distances east or west on a map.
Meridians of Longitude All of the other meridians; the lines of longitude.
The Prime Meridian at 0 degrees longitude is the line on the map that divides east from west. Locations to the east of the Prime Meridian are considered in the Eastern Hemisphere, while locations to the west are in the Western Hemisphere.
The lines of longitude on a map goes from north-south
Either or both.
from west to east and not from north to south
The lines of latitude are lines that go east and west around the globe or map ,the equater us the line in the middle that separates north and south :)
Parallels run east-west on a map. They are lines of latitude that are parallel to the equator.
The lines on a map that show distance from the equator in an east-west direction are called latitude lines. They are also known as parallels and run parallel to the equator. The equator itself is located at 0 degrees latitude.
That depends on how you hold your map or mount your globe.The longitude of any place is the angle east or west between that placeand the Prime Meridian.==========================================Another opinion:The second answer is wrong enough to confuse people. Longitude is an angle.Longitude is not lines, any more than lengths are the marks on a ruler.
It depends on the scale of the map. On a map of the world or a continent, the parallel lines will generally go horizontally across the map - East to West. For a large scale map, showing a small country or a local area, the vertical lines (North - South) will also be shown as parallel.
