A globe is a model of the earth. Globe is to facilitate people to understand the earth. People imitate the shape of the earth and make a model globe of the earth according to a certain proportion. There are deformations in length, area, direction and shape on the globe, so it is almost correct to observe the relationship between various scenes from the globe.

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.
