Geophysics brings together math, physics, and geology to understand the forces at work in the Earth's interior and the interiors of other planets. As a geophysicist, you will use gravity, magnetism, fluid dynamics, and seismology to develop a better comprehension of the unknown through laboratory, field, computational, and theoretical studies. Geophysicists often work in hazard prediction and remediation, the oil and gas industry, research, and government. Geophysics is a subset of Earth and planetary science that uses quantitative tools from physics and math to understand the processes that control the evolution of the interior or the surface of a planet. A geophysicist might analyze seismic or satellite data, conduct laboratory experiments, or construct numerical models of complex systems. Many geophysicists are employed by exploration companies, by academic institutions, and by the government.
