Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is the correct term for the tendency for deformed rock along a fault to spring back to its original shape when its stress is released?
A
Rubber-bandiness
B
Elastic Rebound
C
Aftershock
D
Liquefaction
Explanation: 

Detailed explanation-1: -Elastic Rebound: Tendency for the deformed rock along a fault to spring back after an earthquake.

Detailed explanation-2: -The elastic rebound theory is an explanation for how energy is spread during earthquakes. As rocks on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded.

Detailed explanation-3: -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-4: -Origin of Earthquakes 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.

Detailed explanation-5: -Ground Rupture-Deformation on the ground that marks the intersection of the with the earth’s surface. Effects: Fissuring, displacement of the ground due to movement of the fault.
