This includes its [[geometry|geometric]] description (the [[geoid]]) and the measurement and description of its [[gravitational field]]. Some people involved in the discipline look at [[geodynamics]], the [[Crust (geology)|crust]]s, the [[tide]]s, or the movement of the [[geographical pole]]s. == Related pages == *[[Cartography]] {{-}} {{geo-stub}} [[Category:Geodesy| ]]
