What is the elastic rebound theory explain?

The elastic rebound theory explains how energy spreads during an earthquake. The elastic rebound theory states that as rocks on opposite sides of a fault (which is a fracture or a zone of fractures between two blocks of rock) shift from pressure applied to them, they will gradually gain energy and deform.

What is elastic rebound theory and how does it apply to earthquakes quizlet?

-Rocks rupture or break. -Fault moves (slips) producing displacement. -Elastic strain recovered – energy propagates as seismic waves. Elastic Rebound Theory. The theory that continuing stress along a fault results in a buildup of elastic energy in the rocks, which is abruptly released when an earthquake occurs.

What does the elastic rebound theory explain quizlet?

Elastic rebound theory. IT DESCRIBES THE BUILD UP AND RELEASE OF STRESS DURING AN EARTHQUAKE. Rocks on either side of a fault are locked in place by friction. Rocks will slowly deform over time. When the stress exceeds the strength of the rock, the rocks will fault.

Which of the following is part of the elastic rebound theory?

Which of the following is part of the elastic rebound theory? A rock that has been deformed by movement along a fault can suddenly snap back to its original shape.

Why elastic rebound occurs following slip on a fault during an earthquake?

The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.

How do plate tectonics and elastic rebound theory explain the occurrence of earthquakes?

Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

How does the elastic rebound theory explain the violent tremors that occur during earthquakes?

Which theory is associated with earthquakes quizlet?

The theory of plate tectonics states that the crust(lithosphere) is broken into 16 slabs called plates. These plates are floating on magma and moving around as a result. There are 3 types of plate boundaries and each is associated with earthquakes.

Which one of the following theories explains how earthquakes are generated?

The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

What type of fault caused the 1994 Northridge earthquake?

thrust faults
The thrust faults along which the 1971, 1987, and 1994 earthquakes occurred are the result of a big bend in the San Andreas fault. The bend causes crumpling, or “compression” of the Earth’s crust nearby, giving rise to the thrust faults.

What causes earthquakes?

The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.

What is elastic rebound theory Slideshare?

11. ELASTIC REBOUND THEORY ELASTIC REBOUND THEORY Over the course of time, one can observe that the two sides of an active fault are in slow but continuous movement relative to one another. This movement is known as fault slip.

What causes an earthquake?

What must occur to produce an earthquake?

In elastic rebound theory, what must occur to produce an earthquake? Enough stress must build up over time on a fault to overcome friction.

Which theory explains how earthquakes occur?

How does earthquake occur?

What are the steps that cause an earthquake?

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

Which term describes a current theory of earthquake formation?

Fault creep. is movement along a fault without an accompanying earthquake. Which term describes the current theory of earthquake formation? elastic rebound.

How earthquake are formed?

What is the main cause of an earthquake when the?

What is elastic rebound theory in geology?

Elastic rebound. In geology, the elastic-rebound theory is an explanation for how energy is released during an earthquake. As adjoining plates on the Earth’s surface move in opposite directions, the rocks which span the opposing sides of the incipient fault are subjected to extreme shear stress.

What is the relationship between elastic rebound and storage capacity?

Greater storage capacity will likely cause a more severe earthquake when the elastic rebound occurs, but earthquakes along that fault will be very few. A lower storage capacity will result in earthquakes that are generally less severe, but there will also be more overall earthquakes along that fault.

What is Reid’s theory of the earthquake?

He concluded that the quake must have been the result of the elastic rebound of the strain energy stored in the rocks on either side of the fault. Later measurements using the global positioning system largely support Reid’s theory as the basis of seismic movement.

Where does the stored elastic energy go during an earthquake?

The stored elastic energy has to go somewhere because it has been suddenly released. This is the principle that Reid proposes through his elastic rebound theory of earthquakes. It is a way for the stored energy to be released through a sudden action.
