What is the function of a globe?

The functions are as follows: demonstrating the earth's rotation deflection, demonstrating the alternation of day and night, determining the local time and time zone, determining the relative position between two points on the earth, measuring the field distance between the two places on the surface, and calculating the regional area.

A globe is a model of the earth. Although it can't show all kinds of geographical things and phenomena in detail like a map, and can't fully reflect the actual situation of the earth, it can avoid the errors and deformation of the length, direction, area or shape on the map, and can help us sort out many related concepts of the earth and get the main concepts of the earth.
