Question

Quizplus · Accepted Answer

Stress refers to the force applied to a material, while strain refers to the resulting deformation or change in shape. Therefore, strain is the change in shape of a rock as a result of applied stress. Choice A is incorrect as it describes the measurement of fault offset, which is not related to stress and strain. Choice B is incorrect as it describes stress as resulting from strain, which is backwards. Choice D is incorrect as stress and strain are distinct concepts.
