elastic energy
Blueschist
Faulting under the sea occurs due to tectonic plate movements, where stress builds up along fractures in the Earth's crust. When this stress exceeds the strength of the rocks, it results in a sudden release of energy, causing an earthquake. This process can create underwater faults and can lead to the formation of features such as ridges, trenches, or seafloor spreading zones. The movement can also trigger tsunamis if the seafloor displacement is significant.

Energy is stored in rocks along faults as stress builds up from tectonic plate movements. This stress gradually deforms the rocks until they can no longer hold the energy, leading to a sudden release in the form of an earthquake.
The energy of an earthquake is stored as elastic strain energy in the Earth's crust along the fault line prior to the earthquake. This energy is released when the stress on the fault exceeds the strength of the rocks, causing them to break and the energy to be radiated as seismic waves.
No, stress does not add energy to rocks. Stress typically refers to the force applied to rocks, which can result in deformation and other changes in the rocks' physical properties without adding energy to them.
this type of energy is used when the body is put under stress
Stored mechanical energy refers to potential energy that is stored in an object when it is under stress or compressed, such as a wound-up spring, a stretched rubber band, or water behind a dam. This potential energy can be released and converted into kinetic energy when the object is allowed to move or return to its original state.
No, rocks do not typically form folds under the influence of compressive stress. Folds in rocks are usually formed by tectonic forces such as compression, which causes the rocks to bend and fold. Compressive stress can lead to faulting and fracturing of rocks, rather than folding.
The elastic rebound theory explains how energy is stored in rocks as they deform under stress until they reach a breaking point. When the rocks finally fracture along a fault line, the accumulated energy is released suddenly, causing the rocks to snap back to their original shape. This rapid release of energy generates seismic waves that propagate through the Earth, leading to the shaking felt during an earthquake. Thus, the elastic rebound process is key to the transfer of energy that produces seismic activity.
Strain energy due to torsion is the energy stored in a material when it is twisted under a torque load. It is calculated as the integral of shear stress and strain over the volume of the material. This energy represents the ability of the material to deform plastically under torsional loading.
The term that describes the point below the Earth's surface where rocks under stress break and release energy is called the "focus" or "hypocenter" of an earthquake. This is the location where seismic waves originate, leading to the shaking felt on the surface. The point directly above the focus on the Earth's surface is known as the "epicenter."
Folds are geologic structures that are formed when rocks bend but do not break.
The rocks either fracture under the stress, or become compressed in different rocks known as "metamorphic".
