Spherical models are representations of objects or concepts in a three-dimensional sphere format. They are often used in various fields, such as geography and astronomy, to depict the Earth or celestial bodies. These models help visualize complex data, making it easier to understand relationships and patterns. In education, spherical models can illustrate concepts like the Earth's rotation or the solar system. By using a spherical shape, learners can grasp how different elements interact in space, enhancing their comprehension of topics like geography and physics.
