Because all longitudes converge (merge, meet, come together) at the north and
south poles. Since parallel things can't do that, we know that lines of longitude
must not be parallel, and since they are not parallel, it would be very misleading
to call them parallels. The whole subject is confusing enough as it is.
The main reason why lines of longitude are not called parallels is the fact that
they are not parallel.
Parallel lines never meet, and are the same distance apart everywhere. But the
meridians of longitude all meet in a single point at both the north and the south
poles, and at the equator, any pair of meridians that are 1-degree different in
longitude are about 69 miles apart.
cause they are curved
============================
Actually, it's because they intersect ... something that parallels don't do.
Lines of longitude are often called "meridians", but never "parallels". "Parallels" are lines of constant latitude.
They are called parallels.
Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.
Each 'meridian' is a line of constant longitude.
Not quite. Lines of latitude are called parallels, and they never touch each other. The meridians are lines of longitude, and all of them converge at the poles.

In geography, a meridian is a line of longitude that runs from the North Pole to the South Pole and measures the east-west position of a point on the Earth's surface. The Prime Meridian, located at 0 degrees longitude, is the starting point from which all other meridians are measured.
latitude lines is another name for parallels and longitude lines are called meridians
Because unlike lines of longitude which converge on the poles, lines of latitude are parallel to each other: that is, they never converge.

Lines of longitudes are also called Meridians. These vertical lines are drawn from the North to South poles.The meridian through Greenwich, England, called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth from Greenwich is called the International Date Line (IDL), which is at roughly 180° longitude.
Longitude is the best term, but sometimes meridian is used. The line of longitude at zero degrees is the Prime Meridian.
