Parallels
Parallels are circles that are parallel to the equator.
They are measured in degrees north or south of the equator, with 0° latitude being the equator itself.
The distance between two adjacent parallels decreases as you move towards the poles.
The equator is the longest parallel, while the poles are the shortest.
Parallels are used to determine latitude, which is the measure of how far north or south a location is from the equator.
Meridians
Meridians are semi-circles that run from the North Pole to the South Pole.
They are measured in degrees east or west of the Prime Meridian, which is the meridian that passes through Greenwich, England.
The distance between two adjacent meridians is the same everywhere on Earth.
The Prime Meridian is the longest meridian, while the 180° meridian is the shortest.
Meridians are used to determine longitude, which is the measure of how far east or west a location is from the Prime Meridian.
Meridian
Nothing is parallel to any meridian. The equator is a parallel of latitude, and is parallel to all the other parallels. This is a big part of the reason that, collectively, they are called 'parallels'.
All 'lines' of latitude are parallel to all others.No meridian of longitude is parallel to any others.-- All 'lines' of latitude are parallel to all others.-- No meridian of longitude is parallel to any other one.
The equator is the parallel of zero latitude.
It is a parallel. It is parallel to the equator.
Parallel: 0o latitude
The only lines that can run parallel to the Prime Meridian on any map are other meridians of longitude, and the only map on which they can be printed parallel to it is a Mercator Projection. They are not really parallel to the Prime Meridian.
The equator is a parallel because it is a line of latitude that circles the Earth horizontally, dividing it into the Northern and Southern Hemispheres.
parallel
Vertical lines parallel to the prime meridian are lines of longitude.
There are no geographic lines that are parallel to the Prime Meridian. Technically, every meridian of longitude is parallel to every other meridian of longitude, but only over an infinitesimal distance north or south of the equator. I'm quite sure that's not what you're looking for.
