Soft wood is more susceptible to which type of deformation?

Explanation:
Material stiffness governs how much a material will deform under a given load. Soft wood has a lower modulus of elasticity than hard wood, metal, or glass, so under the same force it tends to bend, compress, or warp more. Moisture and dimensional changes further amplify deformation in soft wood, leading to warping or creep over time. Hard woods, metals, and glass are comparatively stiffer and resist deformation, with glass tending to fail by fracture rather than bend. Because of its lower stiffness, soft wood is the most susceptible to deformation among these options.
