What is the function of lines of latitude and longitude?
That's interesting. How are these lines determined and measured?
The equator is the starting point for measuring latitude, and it is set at 0 degrees. The poles are set at 90 degrees north and south of the equator. As for longitude, it is measured from the prime meridian, which is set at 0 degrees and runs through the Royal Observatory in Greenwich, England. Both latitude and longitude are measured in degrees, minutes, and seconds.
