Geophysical exploration is a method used to study the Earth's subsurface by measuring physical properties like magnetism, gravity, and seismic waves. Scientists use various tools and techniques to gather data, which helps them understand the structure and composition of the ground. This information is crucial for finding natural resources like oil, gas, and minerals, as well as for assessing geological hazards. By analyzing the data collected during geophysical exploration, researchers can create detailed maps of underground features. This process aids in environmental studies, archaeology, and civil engineering, ensuring safer construction and better resource management. Overall, it plays a vital role in our understanding of the Earth.
