The laws modified the heliocentric theory of Nicolaus Copernicus, replacing its circular orbits and epicycles with elliptical trajectories, and explaining how planetary velocities vary.Geophysicists refer to this state of balance with the word "isostasy." Isostasy is like buoyancy -- less dense stuff is buoyant and rides high on the fluid mantle. This partially explains why Earth has continents and ocean basins. The crust is quite thin underneath the oceans, only 5 or 10 kilometers.

Measurements of gravity at the Earth’s surface depend on Earth structures ranging from spatial scales of 1m to 10,000 km. Deeper density structures produce gravity anomalies with a long spatial wavelength. For a body such as a sphere, this would be expressed as a large value for the half-width (x½) .
