The globe shows the lines of latitude and the degrees of north and south. The line labelled 0° longitude is called the Prime Meridian or the Greenwich Meridian and runs through London.

The North Pole is assigned the latitude 90° north and the South Pole latitude 90° south. Lines of longitude, or meridians, are drawn a little differently.

And because one degree of longitude and latitude can actually represent very different distances, we might as well start with the very, very basics. Latitude specifies the north-south position.
