Geophysicists

Geophysicists are scientists who study the physical properties and processes of the Earth using the principles of physics. They investigate the interior structure, crust, oceans, atmosphere, and magnetosphere, as well as surface and near-surface processes such as earthquakes, volcanism, and deformation. They combine observation, experimentation, and modeling to understand how the Earth behaves over varying scales. Geophysicists work in academia, government, and industry, often collaborating with geologists, engineers, and data scientists.

Subfields commonly include seismology, which analyzes earthquakes and seismic waves; geodesy, which measures Earth's shape and

Applications span natural resource exploration, environmental assessment, and hazard mitigation. Geophysicists aid in locating oil, gas,

Education typically requires a bachelor's degree in geophysics, physics, geology, or a related field, with many
