a deeply buried rock is pushed down by the weight of all material above it. Since the rock cannot move, it cannot deform.

Where is the energy of an earthquake stored before the earthquake?
It is stored in the form of elastic strain (also known as elastic potential energy) in the rocks of the crust as they deform under stress.
Is a car a solid?
Cars are made from metal and is therefore Solid
What is stress that pulls and stretches the rock of the crust?
Rocks in the crust are put under a pulling stress, or tensile stress, when tectonic plates are moving apart from one another. A good example of this is the Rift Valley in Africa.
Why did the earthquake in Tokyo Japan on March 11 2011 happen?
Japan is located along what is called a subduction zone, in which one tectonic plate slides into and under another. As these plates move they snag on one another and the rocks deform, building up tension. This is occasionally released in the form of Earthquakes.
What Rocks form under conditions found a few kilometers under earth surface?
Hyperbasal Intrusive Rocks.
Where is the energy of an earthquake stored before the earthquake?
It is stored in the form of elastic strain (also known as elastic potential energy) in the rocks of the crust as they deform under stress.
How is the energy that causes an earthquake stored before the earthquake happens?
It is stored in the form of elastic strain (also known as elastic potential energy) in the rocks of the crust as they deform under stress.
The ability of a material to withstand permanent deformation under tensile stress without fracture is?
Ductility is an objects ability to deform under tensile stress.
What happens to rocks after their elastic limits passed?
They will begin to deform plastically. That is the deformation will be permanent. Depending on the pressure and temperature conditions the rock will either continue to deform very slowly and "flow" (this occurs at great depth under high pressure and temperature conditions) or the rock will undergo brittle failure where fractures form - this occurs at shallow depths with low temperatures and low confining pressures.The rock breaks
What is the unit of ductility?
Ductility means the ability of a material to deform under tensile stress. When a ductile material is being streched it will deform instead of breaking.

What happens to rocks as they go undergo stress?
The rocks either fracture under the stress, or become compressed in different rocks known as "metamorphic".
What is formed when rocks bend under stress but do not break?
Folds are geologic structures that are formed when rocks bend but do not break.
Do Rocks fold typically form under the influence of compressive stress?
Yes.
When rocks are under stress energy is stored in the form of?
elastic energy
What feature is formed when rocks bend under stress but do not break?
Folds are geologic structures that are formed when rocks bend but do not break.
What is Stress reduction factor in UG excavations?
The stress reduction factor is a product of the relationship between the Unconfined compressive strength of a rock and the sigma 1, or principal stress field in that area. The higher the value, the more likely the rock is to deform when placed under load.
