
Lines of latitude and longitude are used to
locate places on Earth.



Distance in degrees (°s) N or S of equator
( ↑ or ↓ )
Parallel to the equator.

0° = Equator
23 ½° N = Tropic of Cancer 23 ½° S = Tropic of Capricorn
66 ½° N = Arctic Circle
66 ½° S = Antarctic Circle
90° N = North Pole
90° S = South Pole



Distance in degrees (°s) E or W of prime meridian.
( ← or → )
Run vertically, pole to pole.

0° = Prime Meridian
◦ Passes through Greenwich, England

180° = International Date Line


Used to locate positions on Earth precisely.
Latitude always first ( ↑ or ↓ )
Longitude always second ( ← or → )
Example:
35° N, 80° W
