As proof, the researchers cite tiny variations in the earth's rotation and gravity field, as well as deflections of continental regions like southern Africanow one kilometer higher than northern Africa.
The largest «bulges» are due to variations in Earth's gravity field.
Small changes in the planet's gravity field can push the satellites together, ever so slightly, or pull them apart — variations that scientists use to interpret the terrain below.
Focus of Study The long - term variation of the Earth's gravity field due to post-glacial rebound and present - day ice melting in the polar regions.
Regional variations arise because the Earth's gravity field is affected in multiple ways by the melt of ice, due to the direct effect of surface mass changes (the gravity field is determined by the distribution of mass), the consequent deformation of the Solid Earth (removing a load causes the Earth's surface to rebound, which in turn changes the distribution of the Earth's mass), the consequent redistribution of ocean water (the ocean surface is shaped by the gravity filed) and perturbations of the Earth's rotation axis (because of mass redistribution).
