4. How to Locate Points on the Earth
In order to locate a point on the surface of the Earth, you must find 2 numbers. A latitude number will be the 1st number and a longitude number will be the 2nd number. These together will determine a point’s location.
Example: 30°N and 90°E means that the 1st number is 30 degrees north of the Equator and the 2nd number is 90 degrees east of the Prime Meridian. If you find
where these 2 lines
meet, you will have
your location!!
