Answer:
You probably mean the lines than run north to south around the earth, like slices of an orange. They are called longitude. It takes 24 hrs for the sun to appear to circle the earth. 360 degrees divided by 24 hrs = 15. A 15th of an hr is 4 min.
its the reason the early navigators had to invent accurate clocks they could carry on ships. Compare your time calculated from solar observation with the time on your clock From GREENWICH ( Zulu longitude), and you can calculate your longitude.
