Can rock undergo compression tension and shear stress all at once and explain?

Yes, it is possible for a rock to undergo compression, tension, and shear stress simultaneously. Compression occurs when the rock is squeezed together, tension occurs when it is being pulled apart, and shear stress occurs when different parts of the rock are sliding past each other in opposite directions. These stresses can result from various geological processes acting on the rock simultaneously, leading to complex deformation patterns within the rock.
