Geophysical exploration is a method used to study the Earth's subsurface by measuring physical properties such as magnetic, gravitational, electrical, and seismic activity. This technique helps scientists and engineers locate natural resources like oil, gas, and minerals, as well as assess geological hazards. The process often involves using specialized equipment to collect data, which is then analyzed to create models of the underground structure. Techniques like seismic surveys, magnetometry, and electrical resistivity are commonly employed in this field, providing valuable information for environmental studies, construction projects, and resource management.
