Geophysics applies physics and mathematics to the structure, composition, and evolution of planets, including Earth. It connects measurements with mechanisms: plate tectonics explains moving crust, the geodynamo explains a planetary magnetic field, and albedo connects reflected sunlight to a planetary surface energy balance. Even a small model can reveal a useful organizing principle, such as the competition between ice-ocean albedo feedback and stabilizing thermal radiation.
Geophysics is the study of the Earth's physical properties and processes using quantitative methods and principles of physics. It encompasses a wide range of topics and techniques to investigate the structure and dynamics of the Earth, including its interior, surface, and the atmosphere.
