Geophysical measurements
Geophysical measurements are techniques scientists use to study Earth's physical properties without digging or drilling. They detect variations in gravity, magnetism, electrical conductivity, or seismic activity to understand subsurface features like mineral deposits, oil reservoirs, faults, and geological layers. Using specialized instruments, these measurements help us map underground structures indirectly, providing valuable information for resource exploration, earthquake studies, and environmental assessment. Essentially, geophysical measurements act as Earth's medical tests, revealing hidden details beneath the surface in a non-invasive way.
