Evidence of isostasy includes the compensation of weights on Earth's lithosphere by buoyant forces in the asthenosphere, as seen in the rebound of crust after glacial retreat. This is supported by measurements of gravity anomalies, topography variations, and seismic data showing different densities of lithospheric materials. Isostasy also explains the relative stability of Earth's crust over geological time scales.

What are the most common evidences of chemical reactions?
Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
What is a theory of isostacy?
The theory of isostasy states that the Earth's lithosphere floats on the denser, semi-fluid layer beneath it (the asthenosphere) in gravitational equilibrium, causing adjustments in the elevation of the Earth's surface due to variations in crustal thickness and density. Isostatic equilibrium occurs when the weight of the lithosphere is balanced by the buoyancy provided by the asthenosphere.
Do mountains keep the earth stable from shakes for example during earthquakes?
No ,mountains do not keep earth from shaking ,greatest earthquakes happen around the mountains like in Himalayas also mountains are created by the movement of the tectonic plates which create earthquakes.Just because the mountains are themselves stabilized by isostacy does not mean that the mountains stabilize the earth or the crust by isostacy. Prof David A Young.No self respecting geologists would claim that mountains keep earth from shaking.
What is the definition of Isostacy theory?
Isostasy theory is a geological concept that posits that Earth's lithosphere is in gravitational equilibrium, with lighter elements floating on top of heavier materials in the mantle. This theory explains how the lithosphere adjusts vertically to maintain balance when weight is added or removed, such as from the melting of ice sheets.
How do isostatic adjustments affect isostacy?
Isostatic adjustments refer to the process where Earth's lithosphere changes in response to the addition or removal of mass on its surface. This can lead to isostasy, which is the balancing of the lithosphere on the denser underlying mantle. Isostatic adjustments can cause the lithosphere to either rise or sink to achieve isostatic equilibrium.

Who is John Pratt?
A mathmatecian who achived many things. He devised a theory of crustal balance which would become the basis for the isostacy principal.
Are their evidences as to the truthfulness of the superstitious beliefs?
There are no scientific evidences for superstitious beliefs. Not only that, but there is no evidence of any kind for superstitious beliefs.
What is isostacy and how does it explain why the earts land masses are not flat?
isostacy refers to equilibrium that exist between part of the crust.in geology the term is used to refer to gravitational equilibrium between lithosphere and asthenosphere. isostacy is explained by isostacy theory that state ;=total mass of the rock in any vertical column of unit cross-section is constant. Two hypothesis are used to explain the earth,that is -principle of mass compensation by J.H Pratt in 1854 -principle of depth compensation by G.B Airy in 1855.
