states that a planet's crust varies in density.
refers to the gravitational equilibrium between the lithosphere and the underlying mantle.
This is done by combing the gravity and seismic crustal structure models in computing the isostatic gravity gradient and solving the VMM inverse problem of isostasy
. For this purpose, we combine three recently developed numerical methods for a regional determination of the Moho geometry from the isostatic gravity gradient.

We point out that in the isostasy
model used by geophysicists, earth is considered fully incompressible.
provides fresh rock from which to make new soil."
Rock-forming minerals of densities less than mantle minerals are deposited; isostasy
Applications of isostasy
and gravity methods are considered in a trio of papers.
Should they hazard an enquiry as to the meaning of such an utterance,I would inform them with smug superiority that isostasy
is in fact a term describing the state of equilibrium when the earth's crust rests on the molten mantle below; and they in turn would probably regret asking.
A 4,700 year record of lake level and isostasy
for Lake Michigan.
* Antarctica's icecap weighs so much it actually pushes the continent's landmass below sea level, a process called isostasy
. If the icecap melted, Antarctica would rise another 450 m (1,500 ft) above sea level.
