Where does isostatic rebound occur?
Where does isostatic rebound occur?
Isostatic rebound occurs when a load is imposed on or removed from the lithosphere. The surface tends to rise or sink as the lithosphere rises or sinks in the asthenosphere. Loads may consist of large lakes, oceans (on continental shelves during eustatic sea level rise), ice, sediment, thrust sheets, and volcanoes.
What is isostatic rebound theory?
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression.
What is isostatic rebound and what kinds of evidence indicates that it has occurred?
Answer Expert Verified Isostatic rebound is also known as post-glacial rebound and crustal rebound. It refers to the rise in the mass of land that was depressed due to the weight of huge glacier at time. Isostatic rebound has occurred in the nature and it is evident in North America, Antarctica, etc.
What is the principle of Isostasy?
Introduction. Isostasy is a fundamental concept in the Geology. It is the idea that the lighter crust must be floating on the denser underlying mantle. Isostatic equilibrium is an ideal state where the crust and mantle would settle into in absence of disturbing forces.
How does Isostasy form mountains?
Isostasy is the key mechanism that links a mountains tectonic, or internal, evolution to its geomorphic, or external, development. When erosion at the surface removes mass, isostasy responds by lifting the entire mountain range up to replace about 80 percent of the mass removed.
What is small amplitude wave?
Small amplitude wave theory. Airy wave theory is strictly only applicable to conditions in which the wave height is small compared to the wavelength and the water depth. It is commonly referred to as linear or first order wave theory, because of the simplifying assumptions made in its derivation.
What is a small amplitude?
A wave’s amplitude is defined as half the distance from its highest point to its lowest point. Amplitude is proportional to the energy of a wave, a high energy wave having a high amplitude and a low energy wave having a low amplitude. the amplitude is the maximum displacement form equilibrium.
What is the amplitude of the wave?
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
What is amplitude of a wave for dummies?
Amplitude is the maximum displacement of the particles of the medium, which is determined by the energy of the wave. A period is the time for one wave to pass a given point.
What is amplitude affected by?
The amplitude of a wave is related to the amount of energy it carries. A high amplitude wave carries a large amount of energy; a low amplitude wave carries a small amount of energy. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave.
