WebThe trench is less deep where the component of subduction is larger. The unusually deep sea floor is not limited to the trench, but also extends farther south toward Puerto Rico. The Puerto Rico Trench is also associated with the most negative gravity anomaly on earth, -380 milliGal, which indicates the presence of an active downward force. WebGravity anomaly maps (see globe below) show how much the Earth’s actual gravity field differs from the gravity field of a uniform, featureless Earth surface. The anomalies highlight variations in the strength of the gravitational force over the surface of the Earth. Gravity anomalies are often due to unusual concentrations of mass in a region.
WebThe gravity anomaly maps presented here (Bouguer, isostatic and surface free-air) are derived from available Earth gravity models (EGM2008, DTU10) and include high resolution terrain corrections that consider the contribution of most surface masses (atmosphere, land, oceans, inland seas, lakes, ice caps and ice shelves). WebAug 30, 2015 · But no, there are no spots on the surface of the Earth where gravity is "missing". To put the anomaly image into context, if you added in the equator-to-poles variation, the image would be a smooth blue-to-red band as you go from the equator to the poles. Oct 17, 2024 at 20:19.
