- 1. Geophysics is a branch of Earth science that involves studying the physical properties and processes of the Earth. It combines principles of physics and geology to understand various phenomena such as earthquakes, volcanic activity, and the Earth's magnetic field. Geophysicists use advanced technologies like seismic imaging, gravity measurements, and magnetometry to investigate the structure and dynamics of the Earth's interior. By studying these properties, geophysicists can also make important contributions to natural resource exploration, environmental monitoring, and hazard assessment.
