gravity survey

A gravity survey measures variations in Earth's gravitational pull at different locations. These differences occur because of variations in underground rock densities, such as mineral deposits, oil reserves, or geological structures. By analyzing gravity data collected through sensitive instruments, geologists can identify subsurface features without drilling. Gravity surveys are useful in natural resource exploration, understanding fault lines, and studying Earth's internal composition. Essentially, the survey detects tiny changes in gravity to create a map of underground formations, helping scientists make informed decisions about subsurface conditions.
