help geographers study location of places. • Latitude: Horizontal lines that run EAST to

WEST. Latitude is the distance north or south of the Equator, measured in units called degrees.

• Longitude: Vertical lines that run NORTH to SOUTH. Longitude is the distance east or west of the Prime Meridian, measured in degrees.

• Philadelphia is located at about 39°N and 75° W on Earth.

• The Prime Meridian marks 0 longitude. It runs from top to bottom of Earth.
