WebThe geoid is essentially the figure of the Earth abstracted from its topographic features. It is an idealized closed equilibrium surface that is formed by the surface of sea water. This is … WebThe geoid is in essence an equipotential surface of the actual gravitational field. In the vicinity of a local mass excess that adds potential Δ U to the normal Earth’s potential at a point, the surface must warp outward in order to keep the total potential constant.

"WebFeb 15, 2005 · The geoid represents oceans as smooth, continuous surfaces unaffected by tides, winds, or currents. It creates a locally horizontal surface against which scientists can measure the downward pull of gravity. Gravity is determined by how much mass a given material has, so the more mass an object has, the stronger its gravitational pull. " - Earth geoid

WebMay 31, 2024 · A geoid represents a hypothetical surface (mean sea level) that the earth’s oceans would follow based solely on gravitational and rotational forces. The geoid surface extends under or over the landmasses and is irregular as it “undulates” above and below the ellipsoid due to irregularities in the mass distribution within the earth.

WebJul 10, 2024 · The surface of a geoid represents a Mean Sea Level (MSL), or a conjecture of the ocean’s surface if tides, winds, and other factors that affect its movements didn’t exist. The only factor that affects the MSL’s shape is the earth’s gravity field.

WebThe geoid is defined as the surface of the earth's gravity field, which is approximately the same as mean sea level. It is perpendicular to the direction of gravity pull. Since the mass of the earth is not uniform at all points, and the direction of gravity changes, the shape of the geoid is irregular.
