Geophysics is a branch of Earth sciences that uses principles of physics to study the physical properties and dynamics of the Earth and its environment. It involves the application of quantitative measurements and analytical techniques to investigate various phenomena such as gravitational fields, magnetic fields, seismic activity, thermal properties, and the electric characteristics of the Earth. Geophysicists analyze data to understand processes like plate tectonics, volcanic activity, and resource distribution (such as oil, gas, and minerals). The discipline encompasses various methods, including seismic surveys, gravity measurements, magnetic surveys, and electromagnetic studies, to explore subsurface structures and gain insights into Earth’s internal processes and composition.
Earth’s inner core, a vast iron-and-nickel sphere, may be undergoing shape changes, affecting scientific understanding. Seismic data from earthquakes suggest changes within the inner core, though they do not pose…
