## What is the sudden return of elastically deformed rock to its original shape caused?

elastic rebound
Earthquakes are a result of elastic rebound. Elastic rebound is the sudden return of elastically deformed rock to its undeformed shape. This process is shown in Figure 1.

What is it called when rock is deformed and then suddenly returned to is undeformed shape?

elastic rebound. The sudden return of elastically deformed rock to its undeformed shape is called. elastic rebound.

### What is the snapping back of deformed rock to its previous shape?

The snapping back of the rock returning to its original shape causes the rock to vibrate, and this is what causes the shaking during an earthquake. The snapping back is called elastic rebound.

What kind of energy is released when the rocks suddenly return to their undeformed state?

Earthquakes occur when energy stored in elastically strained rocks is suddenly released. This release of energy causes intense ground shaking in the area near the source of the earthquake and sends waves of elastic energy, called seismic waves, throughout the Earth.

Rocks have three possible responses to increasing stress (illustrated in figure 3): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed.

How are faults Hypocenters and epicenters related?

How are faults, hypocenters, and epicenters related? The hypocenter is the exact point underground along a fault where the slippage of the two blocks of rock occurs. The epicenter is the point on Earth’s surface that is directly above the hypocenter. The epicenter is located where the three circles intersect.

### What is a sudden vibration of trembling in the Earth?

Earthquakes are vibrations of the Earth produced by the release of energy during a sudden rupture of the Earth.

What type of energy is stored when rocks deform?

Something similar happens in the rock along a fault. Stored elastic energy builds up as the rock is deformed.

## When the rocks suddenly snap the is released?

Sudden motions along faults cause rocks to break and move suddenly, releasing the stored up stress energy to create an earthquake. A slip is the distance rocks move along a fault and can be up or down the fault plane. Slip is relative, because there is usually no way to know whether both sides moved or only one.
