Gravity mapping is a research area that involves creating detailed maps of variations in Earth's gravitational field. These maps are generated using data collected from satellites, aircraft, and ground-based instruments. Gravity mapping helps scientists better understand the internal structure of Earth, including the distribution of mass and density within the planet. By studying gravity anomalies, researchers can gain insights into geological processes, such as tectonic plate movements, volcanic activity, and the formation of mountain ranges. Gravity mapping is also used in industries such as oil and gas exploration, mineral prospecting, and the study of groundwater resources.
