Detailed explanation-1: -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.
Detailed explanation-2: -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.
Detailed explanation-3: -Expert-Verified Answer. The elastic rebound theory describes the build-up and release of stress during an earthquake. Elastic rebound theory explains the occurrence of earthquakes when the earth’s tectonic plates traverse each other.
Detailed explanation-4: -Elastic Rebound Theory states that elastic strain build up movement on fault, which releases energy in the form of seismic waves.
Detailed explanation-5: -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.
