A system of lines is used to find the location of any place on the surface of the Earth. Lines of latitude run in an east-west direction. Lines of longitude run in a north-south direction.
Latitude and longitude
The latitude of ‘a’ is 20ºS…’a’ is 20º south of the Equator.The longitude of ‘a’ is 20ºW…’a’ is 20º west of the Greenwich Meridian.Therefore we write the latitude and longitude of ‘a’ as 20ºS 20ºW.
