What is a "Rocks That Undergo Elastic Deformation Will"? The Most Authoritative Explanation.

How does stress affect rock deformation?

For a given rock, deformation will be different depending on the amount of stress applied. Up to a point, rocks undergo elastic deformation, and will spring back to their original shape after the stress is removed. If more stress is applied, the rock may deform in a ductile manner. If stress increases further, the rock may fracture.

How do rocks deform?

There are different kinds of stress that rocks experience, and these determine how the rocks deform.TTensional stress is when rock is stretched apart. This is similar to pulling on a string from both ends after the string has already been fully extended. Compressional stress is when rock is pressed together.

Why is elastic deformation not recorded in a rock record?

The same is true for rocks, low stress in a rock causes elastic deformation that is not permanent. This is referred to as recoverable strain. This elastic deformation is not recorded in the rock record.

Why do earthquakes cause elastic deformation?

In between earthquakes this elastic deformation builds up until the stress inside the rock exceeds the friction on the fault. So, even though the elastic deformation is released in the surrounding rock, the history of this process is recorded by the earthquake.
