The globe can also contain the imaginary lines that correspond to the meridians and parallels. These allow identifying the location of different points on the map in relation to the latitude and longitude.

The terrestrial globes are usually fixed on a support whose angle of inclination emulates that of the Earth in relation to the Sun, as well as the turning movement known as rotation.
