FTP, identify this idea that there is a balance in buoyancy of all parts of the Earth's crust, coming from the Greek for "equal balance."
The name for this theory was coined in 1889 by Clarence Dutton, although it had been studied for more than a century before. It explains the gravitational attraction of continental and oceanic areas, and for shoreline features being found way inland in regions that were once heavy glaciated. The Pratt hypothesis suggests that crustal blocks have different densities, allowing the depth of crustal material to be the same, while the Airy hypothesis proposed that crustal blocks have the same density but different depths, although neither fully explains this theory.
