What does the elastic rebound theory explain?
Elastic rebound is what happens to the crustal material on either side of a fault during an earthquake. The idea is that a fault is stuck until the strain accumulated in the rock on either side of the fault has overcome the friction making it stick.
What are the steps in the elastic rebound theory?
The five stages of an earthquake are based on the elastic rebound theory, which geologist Henry Fielding Reid devised after the great 1906 San Francisco earthquake.
- Elastic Buildup.
- Dilatancy.
- Influx of Water.
- Earthquake.
- Aftershocks.
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 is the process of elastic rebound theory and why most earthquakes occur at plate boundaries?
Elastic rebound theory states that rock will deform plastically as stresses build up until the stresses become too great and the rock breaks. Earthquakes occur at all types of plate boundaries.
Which statement best describes 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.
Who founded elastic rebound theory?
Henry Fielding Reid
From an examination of the displacement of the ground surface which accompanied the 1906 earthquake, Henry Fielding Reid, Professor of Geology at Johns Hopkins University, concluded that the earthquake must have involved an “elastic rebound” of previously stored elastic stress.
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.
Who invented elastic rebound theory?
During which step of the elastic rebound theory is an earthquake created?
Elastic rebound theory. Stresses build on both sides of a fault, causing the rocks to deform plastically (Time 2). When the stresses become too great, the rocks break and end up in a different location (Time 3). This releases the built up energy and creates an earthquake.
What are 5 types of faults?
When they do, they form faults. There are different types of faults: reverse faults, strike-slip faults, oblique faults, and normal faults.
Who discovered the elastic rebound theory?
What are the 4 main types of faults?
There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.
Theelastic rebound theoryis an explanation for howenergyis spread duringearthquakes. As rocks on oppo-site sides of afaultare subjected to force and shift, theyaccumulate energy and slowly deform until their inter-nal strength is exceeded. At that time, a sudden move-ment occurs along the fault, releasing the accumulatedenergy, and the rocks snap back to their original unde-formed shape.
What does elastic rebound theory mean?
elastic rebound. n. (Geological Science) geology a theory of earthquakes that envisages gradual deformation of the fault zone without fault slippage until friction is overcome, when the fault suddenly slips to produce the earthquake.
What causes an elastic rebound?
Ring of Fire. The Ring of Fire,also known as the Circum-Pacific Belt,is a U-shaped belt that runs along the Pacific Ocean coast for over 24,900 miles.
What is the elastic rebound hypothesis?
What does the Elastic Rebound Hypothesis state? Earthquakes are produced by the rapid release of elastic energy stored in rocks within earth”s lithosphere. When the strength of the rocks present reach or exceed their breaking points, energy is released.
