"Gravity anomaly" is a term used to describe variations in the gravitational field of a particular area relative to the average gravity of the surrounding areas. Other synonyms for this term include "gravity disturbance," "gravity differential," or "gravity irregularity." When studying gravity anomalies, geologists and geophysicists use various measuring instruments, including gravimeters and magnetometers to map and identify the source of these variations. Understanding gravity anomalies can provide insights into the structure and composition of Earth's interior and can also be used in mineral and oil exploration, as different minerals and geological structures can affect the gravitational field in a particular area.
