It contains the essentials, but lacks all of the details. The model airplane is the right shape and the right proportions, but does not have the engine, the controls, the guns, the pilot, and probably won't fly. Yet looking at it evokes an image of the real thing. No one believes Earth is like a globe in every way. But the globe shows all the essentials of location and shape of continents, rivers, oceans, etc.
Different globes show different aspects.
Some show political boundaries. Others show topography. For the model to show all aspects of the real thing it would have to be the real thing. A model may have only limited use as visualization, but may be very effective nonetheless. A good example is the planetary atomic model.
