Because the theory of Isostasy states that the crust floats over the Mantel like a large piece of ice in water, so when a large piece of the crusts deteriorates, like when a extensive glacier melts, the Earth will raise up where the large piece of Earth deteriorate.

The maintenance of hydrostatic equilibrium of the Earth's crust is called?
isostasy
What is meant by equilibrium in geology?
Dynamic equilibrium states that the seismic uplift of an area is balanced by the denudation from that area. For example, As a landscape is uplifted slopes become larger and steeper, revealing more surface area, this surface area weathers through erosion measures such as freeze thaw; chemical degradation; action of plant roots and mechanical stress. These actions create broken and weathered rock and soil particles. These particles are removed through denudation force's, such as fluids, air combined with gravity. and returned (generally speaking) to the sea bed ready for sedimentation and then eventually uplift. This is seen in fluvial geomorphology. As slopes and rivers both act as transport mechanisms for eroded material, and they will adjust there slopes to allow this to happen. Thus if there is more uplift, slopes and rivers will steepen allowing for sediment transport.
How is isostasy a reason for earthquakes?
Isostasy refers to the balance between the Earth's lithosphere (outermost layer) and asthenosphere (plastic layer below). When the lithosphere undergoes stress, such as due to tectonic forces, it can become imbalanced and adjust to achieve equilibrium. During this adjustment process, known as isostatic readjustment, earthquakes can occur as the rocks rupture and release built-up energy. Hence, isostasy can be a contributing factor to the occurrence of earthquakes.
What principal states the earth's crust and lithosphere float on the upper part of the mantle?
it is either the principle of isostasy or tectonics.
Why is earth not in thermal equilibrium with the sun?
because the earth and the sun is not in the thermal contact with each other that is why the earth & the sun is not in thermal equilibrium.
A condition of gravitational equilibrium in the Earth's crust is know as?
isostasy
The maintenance of hydrostatic equilibrium of the Earth's crust is called?
isostasy
What is the definition of isostatic?
An isostatic is something that pertains to or is characterized by isostasy. Isostasy is the equilibrium of the Earths crust.
The principle of continents being in buoyant equilibrium is called?
isostasy
What is Isostacy's theory?
Isostasy (Greek ísos "equal", stásis "standstill") is a term used in geology to refer to the state of gravitational equilibrium between the earth's lithosphere and asthenosphere such that the tectonic plates "float" at an elevation which depends on their thickness and density. This concept is invoked to explain how different topographic heights can exist at the Earth's surface. When a certain area of lithosphere reaches the state of Isostasy, it is said to be in isostatic equilibrium. Isostasy is not a process that upsets equilibrium, but rather one which restores it (a negative feedback). It is generally accepted that the earth is a dynamic system that responds to loads in many different ways, however Isostasy provides an important 'view' of the processes that are actually happening. Nevertheless, certain areas (such as the Himalayas) are not in isostatic equilibrium, which has forced researchers to identify other reasons to explain their topographic heights (in the case of the Himalayas, by proposing that their elevation is being "propped-up" by the force of the impacting Indian plate).In the simplest example, Isostasy is the principle of buoyancy observed by Archimedes in his bath, where he saw that when an object was immersed, an amount of water equal in volume to that of the object was displaced. On a geological scale, isostasy can be observed where the Earth's strong lithosphere exerts stress on the weaker Asthenosphere which, over geological time flows laterally such that the load of the lithosphere is accommodated by height adjustments.Source: http://en.wikipedia.org/wiki/IsostasyBy: Joshua R.

What is the state of equilibrium which sections of the earths lithosphere achieve when vertical forces upon them are unchanged?
isostasy
The state of balance or equilibrium which sections of the earths lithosphere achieve when vertical forces upon them are changed?

Because of isostasy a mountain will ultimately?
The isostasy of a mountain will make it ultimately be eroded to near sea level. This is considered science earth.
Which suggests that earth lithosphere floats on the asthenosphere?
tension or compression or shear or isostasy
What are the weakness of the isostasy theory?
strength and weaknesses of isostasy
How does isostasy impact the surface of the earth?
Isostacy refers to an equilibrium level maintained by the earths crust on top of the mantle. The theory holds that the weight of the earths crust will displace a certain amount of the underlying mantle, and that an equilibrium is reached whereby the mass of the displaced crust and the mass of the displaced mantle are equal, thus holding that part of the crust at a certain height.
