Geophysics is a field of study that applies the principles of physics to understand the Earth's structure, composition, and processes. It involves the use of mathematical models, physical measurements, and computational techniques to study the Earth's interior, surface, and atmosphere. The course covers various topics, including seismology, which examines earthquakes and the propagation of seismic waves, and gravimetry, which explores the Earth's gravitational field. Other areas include magnetism, which investigates the Earth's magnetic field and its interactions with solar activity, and geoelectrics, which focuses on the electrical properties of subsurface materials.

Geophysics also encompasses exploration techniques used in resource discovery, such as oil, gas, and mineral exploration, by utilizing geophysical survey methods like seismic reflection, electrical resistivity, and electromagnetic surveys. Environmental and engineering applications of geophysics include groundwater detection, subsurface contamination assessment, and geotechnical investigations for construction projects. 

The course typically integrates theoretical concepts with practical applications, involving laboratory experiments, fieldwork, and computational modeling. It requires a strong foundation in physics, mathematics, and computer programming, as data analysis and numerical simulations are essential aspects of the discipline. Students in geophysics develop skills in interpreting geophysical data, understanding Earth processes, and applying their knowledge to solve real-world problems in natural hazard assessment, environmental management, and resource exploration.
