What Does The Elastic Rebound Theory?

Which of the following best describes “elastic rebound” theory of earthquakes? As an earthquake occurs, the elastically deformed rocks along the fault spring back to their original shape as much as possible.

What does the elastic rebound theory describe 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.

How is elastic rebound related to earthquakes quizlet?

Elastic-rebound theory is the concept that earthquakes happen because stresses build up, causing rock to bend elastically until slip on a fault occurs.

How elastic rebound theory is related to strain energy and earthquake?

Similarly, the crust of the earth can gradually store elastic stress that is released suddenly during an earthquake. This gradual accumulation and release of stress and strain is now referred to as the “elastic rebound theory” of earthquakes.

Which theory best explains earthquake motion?

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

What are the four types of seismic waves which are body waves and which are surface waves?

There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.

What are the four types of seismic waves which are body waves and which are surface waves quizlet?

P (primary) waves-compressional seismic waves that move through the body of the Earth. S (secondary) waves-seismic shear waves that pass through the body of the Earth. Surface waves(L-waves, R-waves)-seismic waves that travel along the Earth’s surface.

Which type of fault forms when the Earth’s crust is pulled apart by extension?

Normal faults create space. Two blocks of crust pull apart, stretching the crust into a valley. The Basin and Range Province in North America and the East African Rift Zone are two well-known regions where normal faults are spreading apart Earth’s crust.

What is elastic rebound theory Slideshare?

Elastic Rebound Theory • According to the theory, the rocks on each side of a fault are moving slowly. • If the fault is locked, stress in the rocks increases.

Why is elastic rebound theory important?

Elastic rebound theory fits in well with the theory of plate tectonics and helps explains the cyclical nature of many earthquakes including why earthquakes repeatedly occur in the same regions.

What must occur to produce an earthquake quizlet?

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 claim explains how elastic rebound takes place?

The energy released by an earthquake is the result of elastic rebound. Which claim explains how elastic rebound takes place? Pressure builds on rocks until they suddenly collapse.

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

Elastic rebound theory

Before an earthquake, the buildup of stress in the rocks on either side of a fault results in gradual deformation. Eventually, this deformation exceeds the frictional force holding the rocks together and sudden slip occurs along the fault.

What are the three 3 types of seismic waves?

There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.

Which seismic waves are considered body waves quizlet?

Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as “body waves”.

What are three types of seismic waves quizlet?

Three types of seismic waves are P waves, S waves, and surface waves.

What are 4 seismic waves?

Love Waves—surface waves that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation..

  • P-wave Motion. P-wave:the primary body wave; the first seismic wave detected by seismographs; able to move through both liquid and solid rock. …
  • S-wave Motion. …
  • Rayleigh-wave Motion. …
  • Love-wave Motion.

What is main types of seismic waves?

The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

What are the types of seismic waves?

There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

What are the two theories that support plate movement?

The theory of plate tectonics is what brings together continental drift and seafloor spreading.

What is earthquake theory?

Earthquakes are caused by a sudden fracture of rock masses along a fault line. … According to the theory, a tectonic earthquake occurs when strains in rock masses have accumulated to a point where the resulting stresses exceed the strength of the rocks, and sudden fracturing results.

Why rubber band is stretched how it is connected to the elastic rebound theory?

This is what happens in a rubber band. As you stretch a rubber band, the material stores elastic energy, and its desire to snap back is the stored elastic energy. Once there is a lot of elastic energy stored, you can let it go.
