Which directions does a Parallel go?

Answer 1

If you mean a 'parallel' of latitude on the earth, then it is a circle that proceeds east and west from any point on it. There can be any desired number of them, the only specification being that every point on the 'parallel' has the same geographic latitude. Since these are all curved lines, it's hard to say that they are parallel in the same sense as parallel straight lines on a flat surface. But the planes they lie in are all truly parallel planes.
