Geographers use parallels of latitude and meridians of longitude to locate any place on Earth. Parallels are horizontal circles around the globe, perpendicular to the equator. Meridians are vertical lines from pole to pole. The equator and prime meridian divide the globe into hemispheres and measure degrees.

1. Geographers divide the globe in vertical and horizontal imaginary lines to be able to locate any place on Earth by using the imaginary grid created by those lines.
Parallels of latitude are imaginary circles traced from East to West around the globe. They are perpendicular to the Earth’s axis. The main parallel is the Equator, located halfway between the North and South Poles and divides the globe into the Northern and Southern hemispheres. They are measured in degrees from 0° to 90°.
Meridians of longitude are the vertical imaginary lines running from pole to pole. They are measured in degrees (°) starting with the Prime Meridian (Greenwich Meridian) both to the east and to the west. They are counted from 0° to 180°.
