Geophysics is the study of the physical processes and properties of the Earth, such as its structure, composition, and dynamics. This field encompasses a wide range of scientific disciplines, including seismology, geomagnetism, geodesy, and heat flow studies. Geophysicists use a variety of techniques, such as seismic imaging, gravity and magnetic surveys, and remote sensing, to study the Earth's interior and its interactions with the atmosphere, hydrosphere, and biosphere. The goal of geophysics is to better understand the Earth's processes and to use this knowledge to address practical challenges, such as natural resource exploration, environmental monitoring, and hazard assessment.
