The Hayford-Bowie concept estimates the depth of compensation to be roughly 70 kilometers, a depth at which the total weight per unit area is equal around all the Earth.
The Heiskanen hypothesis of this principle is a compromise between the earlier Airy and Pratt hypotheses. The Hayford-Bowie concept estimates the depth of compensation to be roughly 70 kilometers, a depth at which the total weight per unit area is equal around all the Earth. Coined in 1889 by Clarence Dutton from the Greek for "equal balance," FTP, identify this geological idea that continents are less dense and float on a mantle.
