When do rocks deform?
A)after their bonds weaken when they get really old
B)only during major earthquakes
C)whenever they are subjected to stresses or strain rates which exceed their own strength
D)when they are quarried or mined, otherwise they are too strong to break under natural conditions

Question

Quizplus · Accepted Answer

Rocks can deform whenever they are subjected to stresses or strain rates that exceed their own strength, whether it is due to natural processes or human activities such as quarrying or mining. The weakening of bonds due to age is not the only factor that influences rock deformation, and deformation can occur even without major earthquakes.
