Which natural process of materials returning to their natural states is listed?

• A. Oxidation
• B. Corrosion
• C. Decomposition
• D. Erosion

Answer: (B)

Corrosion is the natural chemical process where metals react with their environment to form compounds such as oxides or hydroxides. In salty, humid air, moisture and oxygen drive reactions that change the metal from its pure form into a more stable compound. That transition—metal to oxide or similar corrosion product—is why corrosion is described as returning materials toward their natural state. Oxidation is part of corrosion (a specific reaction with oxygen), but corrosion covers other chemical reactions as well. Decomposition is breaking down into simpler substances, not the metal’s typical corrosion products, and erosion is physical wearing away, not a chemical change. In parachute rigging, this matters because corrosion can weaken hardware, so coatings, sealants, and proper protection against moisture and salt are key to extending service life.
