That's like asking "How many inches is there between the marks on a ruler ?"
That depends on the ruler. It may be marked in 32nds of an inch, 16ths of an inch,
8ths of an inch, 4ths of an inch, half-inches, or whole inches.
There is no standard set of 'lines' of latitude or longitude. Some maps or globes have
a line printed every 30 degrees, some every 15 degrees, some every 10 degrees, and
some have no lines at all. The mapping software I use can print a line every 0.033
minute if I need it, but that would be 324,000 lines of latitude between the north
and south poles, and I wouldn't be able to see the places under the lines.
There are 360 degrees of longitude around the whole Earth, and 180 degrees of
latitude between the poles. You're welcome to draw as few or as many lines as
you're comfortable with. There are 60 minutes in each degree.
"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
Peel an orange. The lines between the sections of the orange are similar to the pattern of longitude lines on the globe.
Lines of longitude appear vertical with varying curvature in this projection, but are actually halves of great ellipses, These lines met at the poles but the distances between these lines are divided into degrees, minutes and seconds. There is no unit expressed as a "pole."
Lines of longitude are imaginary vertical lines that represent the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime Meridian (Greenwich). Lines of longitude are often referred to as meridians. The lines of longitude run from the North pole to the South pole and at the poles all the lines of longitude intersect at a single point.
The Equator
Greece is in between 15 and 30 degrease East.......so that means it is about 20 degrease east in lines of longitude.

If you pick a longitude and mark a dot at every point on Earth with that longitude, the dots will form a line between the north and south poles. The imaginary line is called the "meridian" of that longitude.

Minutes (1/60 of a degree) and seconds (1/60 of a minutes). After that you use decimals of a second.
