Gravity measurements refer to the scientific study of the Earth's gravitational field. This field is not uniform, as it varies due to factors such as the distribution of mass within the Earth, topography, and geological structures. By conducting gravity measurements, researchers can gain valuable insights into the Earth's interior structure, the movement of tectonic plates, and even detect underground resources such as oil and minerals. Gravity measurements are typically conducted using specialized instruments such as gravimeters and are an important tool in geophysics, geodesy, and other Earth science disciplines.
