What is the sudden return of elastically deformed rock to an underformed shape?
The sudden return of elastically deformed rock to its undeformed shape is known as elastic rebound. This phenomenon occurs when stress on the rock exceeds its elastic limit, causing it to deform temporarily. When the stress is released, the rock snaps back to its original shape, often releasing energy in the form of seismic waves, which can result in an earthquake. This process is fundamental to understanding how stress accumulates and is released in geological formations.
When does an elastic rebound happen?
The sudden return of an elastically-deformed rock to its original shape when a load is removed or a stress released. This often occurs in earthquakes, as rocks either side of a slip fault, which have been stressed by friction along the fault plane, overcome static friction and rapidly rebound. Elastic rebound must not be confused with isostatic rebound, which is a much slower process in which mantle material flows under pressure into areas under the crust where large loads such as oceans or ice sheets have been removed, thus forcing the crust to rise where the load has been removed and fall elsewhere. Because of the large scales involved and extremely high viscosity of the mantle material, isostatic rebound very slow. The ground surface in the area of Scandinavia is still rebounding at a measurable rate (about 10mm per year) as a result of the melting of the Weichsel ice sheet ten thousand years ago.
Is rubber reversible?
Rubber is not reversible in the sense that once it is stretched or deformed, it generally does not return to its original shape. However, rubber can be melted down and reformed into new shapes or products, which is a form of reversible transformation.
Is cellulose an elastomer?
No, cellulose is not an elastomer. Cellulose is a structural polysaccharide found in plants that provides rigidity and strength to cell walls. Elastomers are synthetic or natural polymers with elastic properties that can return to their original shape after being stretched or deformed.
What is the ability of matter to return to its original state?
The ability of matter to return to its original state after being deformed or altered is known as elasticity. Elastic materials can stretch or compress under stress and then return to their original shape once the stress is removed. This property is essential in various applications, ranging from rubber bands to structural engineering. The degree of elasticity varies among different materials, influencing their behavior under different conditions.
Sudden return of elastically deformed rock to an undeformed shape?
No
Sudden return of elastically deformed rock?
The sudden return of elastically deformed rock to its original shape may indicate the occurrence of an earthquake or other tectonic activity that released accumulated stress within the rock. This phenomenon is commonly observed in regions with high seismic activity, where rocks experience deformation due to the build-up of strain energy before ultimately rebounding to their undeformed state when stress is released.
What is the sudden return of elastically deformed rock to an underformed shape?
The sudden return of elastically deformed rock to its undeformed shape is known as elastic rebound.

This process is fundamental to understanding how stress accumulates and is released in geological formations.
Sudden return of elastically deformed rock to its undeformed shape?
This phenomenon is known as elastic rebound. When rocks experiencing elastic deformation reach their limit, they release stored energy and snap back to their original shape, often causing an earthquake. This process is commonly observed along fault lines where tectonic plates meet.
Why does energy stored in deformed material in only its elastic portion?
The "elastic portion" is precisely the part where the material returns to its original shape, and thus returns its energy. Once the material does NOT return to its previous shape, it doesn't exert a force back to the original position, and there is no way to get the energy back.
What is the process by which deformed rocks return to its original shapes?
elastic change

Which term describes the ability of a solid to return to its original shape?
Elasticity describes the ability of a solid to return to its original shape after being deformed or stretched.
What is an example of elasticity?
Most materials are elastic - or behave elastically - at least a little bit. This means that when you apply forces to them to deform them, they return to their original size and shape after the deforming forces are removed.
What name is given to a material which returns to it's original shape after being deformed?
elastic
What part of the line represents the elastic deformation of the material?
The linear portion of the stress-strain curve represents the elastic deformation of a material. This is where the material behaves elastically and will return to its original shape once the applied stress is removed.
How does the elastic rebound theory explain the occurrence of earthquakes?
The sudden return of elastically deformed rock to sit original shape is called elastic rebound. Elastic rebound happens when stress on rock along a fault becomes so grat that the rock breaks or fails. This failure causes the rocks on either side of the fault to jerk past one another. During this sudden motion, large amounts of energy are released. This energy travels through rock as seismic waves. These waves cause earthquakes. The strength of an earthquake is related to the amount of energy that is released during elastic rebound.
