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.

What are some common isostasy problems encountered in geology and how do they impact the Earth's crust?
Common isostasy problems in geology include crustal rebound, subsidence, and isostatic adjustment. These issues can impact the Earth's crust by causing changes in elevation, leading to geological hazards such as earthquakes, volcanic activity, and landslides. Isostasy problems can also affect the stability of the Earth's surface and contribute to the formation of mountain ranges and ocean basins.
What is assess the statement Isostasy never stops causing upift and subsidence.?
The statement "Isostasy never stops causing uplift and subsidence" reflects the ongoing nature of isostatic adjustments in the Earth's crust. Isostasy refers to the gravitational equilibrium between the Earth's lithosphere and asthenosphere, where changes in surface load—such as erosion, sediment deposition, or glacial melting—can lead to vertical movements of the crust. These adjustments can occur over geological timescales, meaning that while they are continuous processes, the rates and effects can vary significantly. Therefore, while isostasy is a constant process, the extent and impact of uplift and subsidence can fluctuate based on environmental and geological conditions.
Do all meteors impact on Earth's surface?
Not all meteors impact the surface of the earth. Many burn up in the atmosphere prior to impact. The majority of meteors that do reach the earth's surface usually impact desolate regions.
What is the concept that rocks of the crust and upper mantle are floating in gravitational balance?
The concept you are referring to is called isostasy. Isostasy explains how the Earth's lithosphere (crust and upper mantle) floats on the denser underlying asthenosphere in gravitational equilibrium, with thicker crust floating higher and thinner crust floating lower to maintain balance. This concept helps explain variations in topography and subsurface structure of the Earth's surface.
The maintenance of hydrostatic equilibrium of the Earth's crust is called?
Isostasy. This is the balance between the weight of the Earth's crust and the buoyant force exerted by the mantle beneath it, ensuring that the crust remains in a state of equilibrium.
Which suggests that earth lithosphere floats on the asthenosphere?
tension or compression or shear or isostasy
What is isotasy?
Isostasy is the balancing of the Earth's crust on the denser underlying mantle. This process helps explain variations in elevations of landmasses and adjustments in response to changes in surface loads like glaciers or erosion.
What energy sources causes new rock to reach the earth's surface?
Erosion from weathering owes it's power source to the sun. The weather causes rocks to be newly exposed at the surface. Heat from the Earth's interior causes molten material to rise to the surface, creating new rock.
What are the weakness of the isostasy theory?
strength and weaknesses of 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.

The principle of continents being in buoyant equilibrium is called?
isostasy
Which planet has a cratered surface similar to earth's surface?
Mars. However you are wrong in implying that Earth's surface IS cratered, it is not andy impact craters have been modified by Earth's geological processes and are not obviously visible today.
