The lines that intercept latitude lines are lines of longitude.
There can be various lines on a map, but the ones you are probably thinking of are 'latitude' and 'longitude'.
A map with parallel lines of latitude and longitude is known as a Mercator projection map. This type of map is often used for navigation purposes due to its representation of straight lines of latitude and longitude, making it easier to measure distances and plot courses. However, the Mercator projection distorts the size of landmasses, especially near the poles.

Latitude and Longitude are used to point to exactly where you want to be
The cartographer, publisher, or printer of the map does that.
No. You are describing lines of longitude.
