Why does the word hemisphere describe the six globes?

The term "hemisphere" refers to half of a sphere, and in the context of the six globes, it describes the division of each globe into two equal halves: the Northern and Southern Hemispheres. This division allows for the representation of geographical, climatic, and cultural distinctions across the globe. Additionally, the six globes often refer to different regions of the Earth, such as the Eastern and Western Hemispheres, further emphasizing the concept of division into halves for ease of study and understanding.
