How does the elastic-rebound theory explain the occurrence of earthquakes? Choose one: A. Colliding rocks cause kinetic energy to travel through the crust in the form of earthquakes. B. When bending rocks fail, stress energy is released in the form of earthquakes. C. The bending motion of crustal rocks causes the surrounding crust to vibrate as earthquakes. D. When bending rocks fail, tension energy is released in the form of earthquakes.

The elastic-rebound theory explain the occurrence of earthquakes in b. When bending rocks fail, stress energy is released in the form of earthquakes.

Explanation:

The energy released as earthquakes result from when bending rocks fail and there is a rupture from the fault line. Because earthquakes are sudden movements from ruptures, the answer a is not correct. c. is also not correct because it is not the surrounding crust that vibrates but the crust is divided between two moving plates. d is also not correct because the opposite rocks are under sheer stress and the energy released is a stress energy, not a tension energy.
