Latitude and longitude are angles that describe the location of a point on the Earth's
surface. Longitudes range from zero to 180 degrees east or west. Latitudes range from
zero to 90 degrees north or south.
There are no official 'lines'. Some maps or globes have some lines printed on them to
show where a few latitudes and longitudes are, and other maps and globes have no
lines at all printed on them. I have mapping software that can print 324,000 latitude
lines and 648,000 longitude lines if I want them, but I have never needed them yet.

latitude?
Florida does have Longitude and Latitude lines, and while they are documented on maps of this area and in many other ways the measurements were done many many years ago.
Each 'meridian' is a line of constant longitude.
Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.

Every line of longitude intersects with every line of latitude and vic-versa.
Latitude and longitude
The lines that intercept latitude lines are lines of longitude.
Every parallel of latitude crosses every meridian of longitude.
Longitude lines go vertically and latitude lines go horizontally.
Lines of latitude and longitude allows any position on the Earth to be plotted.
