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.
In the process of elastic rebound as a rock becomes stressed it first?
In the process of elastic rebound, as a rock becomes stressed it first deforms elastically, storing energy in the form of strain in the rock. Once the stress exceeds the rock's strength, it suddenly breaks and releases the stored elastic energy, causing an earthquake. This sudden release of energy results in the rock snapping back to its original shape, causing the ground to shake.
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.
What kind of metamorphic rock is formed where rocks have been heated but not deformed?
A metamorphic rock formed where rocks have been heated but not deformed is called a contact metamorphic rock. This type of rock forms when existing rocks are altered by the heat from nearby magma without experiencing significant pressure or deformation. Examples include hornfels and marble.
Which of earths mechanical layers is easily deformed?
The asthenosphere, located in the upper mantle, is easily deformed due to its semi-molten state. This layer allows tectonic plates to move on the ductile rock beneath them.
Sudden return of elastically deformed rock to an undeformed shape?
No
Sudden return of elastically deformed rock to its unformed shape?
This phenomenon is known as elastic rebound and it occurs when a rock that has been subject to stress suddenly releases that stress, causing it to return to its original shape. This can happen during an earthquake when built-up strain in the rock is released, leading to rapid deformation and rebound.

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.

What is the snapping back of deformed rock to its previous shape called?
Elastic rebound
The snapping back of deformed rock to its previous shape is called .?
Elastic rebound
What is the sudden movement of a rock masses as a result of tech tonic earthquakes?
The sudden movement in rock mass causes earthquakes. This is when the rock mass comes together and collapses.
What is the name of a rock when it becomes permanently deformed without breaking?
When a rock deforms without breaking it is often called "folded".erosion
