Ah, ha! Found You!

Knowing where you are or where you are going is a necessary part of being alive. We (humans, that is) long ago people split the Earth into lines of latitude and longitude in order to help with navigation. 

Latitude lines are lines around the Earth moving from north to south, and a person’s latitude determines how far north or south they are in degrees. At the equator, the latitude is 0° and it is 90° at the poles. 
! 
Longitude lines, or meridians, circle the Earth from east to west, and a person’s longitude determines how far east or west they are in degrees. The meridian that passes through Greenwich, in London, is set at 0° longitude for historical reasons.
