Gravimetry is a scientific technique used to measure the strength of gravitational forces at specific locations on Earth. By analyzing variations in gravity, scientists can gather information about the distribution of mass beneath the Earth's surface, which helps in understanding geological structures and processes. This method is commonly employed in fields such as geophysics, mineral exploration, and environmental studies. Gravimetric data can reveal insights about subsurface resources, such as oil and gas deposits, and assist in monitoring changes in glacial movements and sea level rise.
