Geophysical models are simplified representations of the Earth's physical properties and processes. They help scientists understand complex systems like plate tectonics, earthquakes, and volcanic activity. By using data from various sources, such as satellite measurements and seismic surveys, these models simulate how different forces interact within the Earth. These models can be used to predict natural events and assess risks, making them valuable tools for researchers and policymakers. They also aid in resource exploration, such as locating oil and minerals. Overall, geophysical models play a crucial role in advancing our knowledge of the Earth's dynamics.
