meridians
There are no parallels of longitude, because longitudinal lines aren't parallel. We call them "meridians". Lines of latitude ARE parallel, and so the expression "45th parallel" would be an accurate description.
another name for a line of longitude is meridian.
A "meridian" is a line of constant longitude.
latitude lines is another name for parallels and longitude lines are called meridians
Every 'line' of constant longitude is a 'meridian'.
Each 'meridian' is a line of constant longitude.
For Maps, it is latitude and longitude.
Lines of longitude are also known as meridians. They run north-south and measure east-west.
All of the longitude "lines" merge at the north and south poles, so you might say that they 'start' at one of these points and end at the other one. If the question means to ask: "Where is the line of zero longitude ?", then the answer is: The origin of longitude is defined as the Prime Meridian, an imaginary line between the north and south poles that passes through the Royal Observatory in Greenwich, England.
