An example of isostasy is when the Earth's crust adjusts its elevation in response to changes in the distribution of mass, such as the melting of glaciers. As the glaciers melt, the weight on the crust decreases, causing the land to rebound and rise up in a process known as post-glacial rebound. This is a common phenomenon in areas that were covered by ice sheets during the last ice age.
What else can I help you with?
The principle of continents being in buoyant equilibrium is called?
isostasy
What are the three type of isostasy?
Three principal models of isostasy are:The Airy-HeiskanenModel- where different topographic heights are accommodated by changes in crustal thickness, in which the crust has a constant density The Pratt-HayfordModel- where different topographic heights are accommodated by lateral changes in rock density. The Vening Meinesz, or Flexural Model- where the lithosphere acts as an elastic plate and its inherent rigidity distributes local topographic loads over a broad region by bending.
Who discovered the isostasy theory?
Isostasy theory was developed by the American geologist Clarence Edward Dutton in the late 19th century. He proposed that the Earth's crust is in equilibrium, with less dense crust floating on top of the denser mantle.
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.
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 principle of continents being in buoyant equilibrium is called?
isostasy
As erosion removes the tops of mountains the crust will rise upwards This is an example of what?
This is an example of isostasy, which is the concept that the Earth's lithosphere (crust) floats on the semi-fluid asthenosphere below. As material is eroded from the top of mountains, the lithosphere readjusts to maintain equilibrium, resulting in the rising of the crust.
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.
What are the three type of isostasy?

The Vening Meinesz, or Flexural Model- where the lithosphere acts as an elastic plate and its inherent rigidity distributes local topographic loads over a broad region by bending.
The balance between gravity and buoyancy is called?
The balance between gravity and buoyancy is called equilibrium.
What is a sentence using isostasy?
Monkey
What are the weakness of the isostasy theory?
strength and weaknesses of isostasy
What is the state of balance of the lithosphere called?
isostasy
How isostatic adjustments affect isostasy?
Gravity.
What did the theory of isostasy states?
everything on the crust is in a state of balance
Is Isostasy a type of stress?
Isostasy itself isn't a type of stress. Restoring isostasy, however, puts stress on the crust. Allow me to explain: Isostasy is the process of the earth's crust floating on the mantle. When the crust suddenly gets heavier (this happens during an ice age close to the poles, the weight of the ice pushing the crust down), the crust will sink deeper into the mantle. This process is called "restoring the isostasy". The isostasy is reached when the upward force from the mantle (the buoyant force) and the downward force from the crust (gravity) are in balance again. When an ice age ends, the isostasy will be disrupted again, because all the weight of the ice on the crust will be gone. The crust will start to rise again, using the same forces as before, but in a reverse way. This process is still going on in Scandinavia, where the crust is still lifting up from the last ice age. As with all geological processes, restoring isostasy isn't fast: it can take thousands of years to restore the isostasy. Analog to the isostacy (but a lot quicker), is when you push down an icecube in a glass of water. The icecube will get lower into the water, as you push it down. but it will push back, because it's lighter then the water, and the buoyant force tries to make it float as good as possible. When it doesn't move anymore, it means the buoyant force and the force you are applying with your finger are in balance, and isostasy is reached.
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.
