Geodesy.
Geodesy - a branch of applied mathematics that deals with the shape, area, dimensions, curvature and the position of geographical points on the earth. Also called geodetics.
Earth science or Geoscience refers to science that studies the Earth. Here are its field of studies: Geology, Physical geography, Geophysics and Geodesy, Soil Science, Ecology, Hydrology, Glaciology, and Atmospheric Sciences.
Like an irregularly peeled off orange.The deepest point in the Pacific Ocean is 10.9 km. The diameter of the earth at the equator is 12,756 km. Therefore, the ratio of the liquid to the solid depth is approx. 11:13,000. Thus, the shape of earth without water would not be much different from its oblate spheroid as computed by Newton.P.S. - Geodesy is the science that studies the shape and size of the Earth. The earth's equatorial diameter is 7,926 miles, while its polar diameter is 7,900 miles the difference is only 26 miles.About 70% of the earth's surface is covered with water.
Geodesy measures the various positions and points on the Earth.

Space geodetic methods were brought to geodesy in the 20th century.

I think it is used for recognising the density of different parts of the earth....
