How do we know why some rocks break and others flow?
What will be an ideal response?
Answer: "At different combinations of stress and strain rocks exhibit elastic, brittle, or plastic deformation. Increasing confining pressure increases rock strength and leads to plastic flow rather than brittle fracture. Increasing temperature decreases rock strength and enhances plastic flow."
