Latitude is angular distance measured north and south of the Equator. The Equator is 0 degrees. As you go north of the equator the Latitude increases all the way up to 90 degrees at the north pole. If you go south of the equator, the Latitude increases all the way up to 90 degrees at the south pole.
Lines of Longitude define how far east or west a location is from the Prime Meridian, the focus of this lesson. The Prime Meridian is an imaginary line that, similar to the equator, divides the earth into eastern and western hemispheres. It is sometimes referred to as the Greenwich Meridian. All lines of latitude and longitude are measured in degrees.
