depth of compensation वाक्य

Pratt on the other hand suggested that there was a lower density under mountains below sea-level ( actually refined later and termed the depth of compensation ) and that this is offset by the mass above sea-level.
The principle of isostasy states that when free to move vertically, lithosphere floats at an appropriate level in the asthenosphere so that the pressure at a depth of compensation in the asthenosphere well below the base of the lithosphere is the same.
where Y is the tectonic or corrected subsidence, \ rho _ m is the density of the mantle, and b is the distance from the base of the unloaded crust to the depth of compensation ( which is assumed to be at the base of the loaded crust ) and is given by:
