KnowraEarth's gravity fieldLinked fromLinked fromThe 8 pages that link to Earth's gravity field, each with the reason it gives.All 8Broader topic 1Related 5Narrower topic 2GeodesyBroader topic: Its variations reveal mass distribution and affect the reference surfaces used in height measurement.GeoidNarrower topic: Variations in this field determine the geoid’s departures from a smooth reference ellipsoid.Gravity anomalyNarrower topic: Anomaly maps describe departures within this field from a reference model.Satellite geodesyRelated: Its unevenness alters satellite orbits and is itself mapped by satellite missions.Earth's massRelated: Its large-scale strength reflects Earth's mass, while variations reveal uneven mass distribution.Internal structure of EarthRelated: Gravity measurements constrain how density is distributed through the planet.Equatorial bulgeRelated: Earth's nonspherical mass distribution makes gravity vary with latitude and altitude.Physical geodesyRelated: Its variations are the central physical observations and unknowns of the discipline.
