geophyysics
Geophysics is the physics-based study of the Earth's interior, structure, processes, and dynamic systems, using measurements of physical fields and properties. It applies quantitative methods to understand the planet from the surface to the core and also extends to other planetary bodies. It overlaps with geology, geodesy, and engineering, and contributes to both fundamental science and practical problems.
Subfields include seismology, which analyzes earthquakes and seismic waves to image the Earth's interior; gravity and
Common tools are seismometers, gravimeters, magnetometers, magnetotelluric rigs, electrical resistivity meters, ground-penetrating radar, borehole logging, and
Applications range from understanding plate tectonics and mantle convection to locating oil, gas, minerals, and geothermal
Planetary geophysics applies similar techniques to other planetary bodies. The field relies on interdisciplinary collaboration among
