An "Earth Model" refers to a representation of the Earth used to understand its structure, processes, and systems. These models can be physical, like globes, or digital, such as simulations that illustrate geological or atmospheric phenomena. They help scientists study aspects like climate change, plate tectonics, and ocean currents. Different types of Earth Models serve various purposes. For example, geological models focus on the Earth's layers and materials, while climate models predict weather patterns and changes over time. By using these models, researchers can visualize complex interactions and make informed decisions about environmental issues.
