Which term describes damage caused over time to components caused by physical processes, leading to failure?

Explanation:
Damage that builds up slowly as materials experience ongoing physical processes over time is described as degradation. This captures the idea that properties weaken gradually due to wear, fatigue, corrosion, creep, radiation effects, or other service conditions, eventually increasing the chance of failure. The other terms describe different concepts: brittleness is a tendency to fracture with little plastic deformation, ductility is the ability to deform plastically, and elasticity is the ability to return to original shape after deformation. So, degradation best fits the scenario of time‑dependent, progressive damage leading to failure.
