What is pratt theory about isostasy?

The Pratt theory of isostasy is one explanation for the interaction between lithosphere and asthenosphere as it pertains to differences in surface elevations. It describes the isostasy as it relates to rock density differences at different topographical heights.

What is meant by isostasy?

Isostasy is a term used in geology which means a general equilibrium of the forces tending to elevate or depress the earth's crust.

What is meant by equilibrium in geology?

In the field of geology, equilibrium is defined as "Isostasy" or a gravitational equilibrium between the earth's lithosphere and its Asthenosphere. When a particular area of the lithosphere reaches Isostasy, it is said to have reached Isostatic Equilibrium. In other… Full Answer

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… Full Answer

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… Full Answer

What happens during isostatic rebound?

Post-glacial rebound (sometimes called continental rebound, glacial isostasy, glacial isostatic adjustment) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostasy.
