Answer:
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.

Answer:
D disruption of hibernation or migration cycles
Schist
Option 2.
<u>Explanation:</u>
Schist is a type of a metamorphic rock but it is a medium grade of these metamorphic rocks. It is formed by the metamorphosis of the mud stone or the shale.
These type of metamorphic rocks can also be formed from igneous rocks provided these have been subjected to higher degrees of temperature or pressure. These are type of rocks which do not solidify from magma even despite subjection to intense heat and pressure.
