Final answer:
The condition and composition of the metal surface can affect general corrosion. A rough and impure metal surface is more susceptible to corrosion, while certain metals form protective oxide films to prevent further destruction.
Step-by-step explanation:
Corrosion is a galvanic process by which metals deteriorate through oxidation. The condition and composition of the metal surface can affect general corrosion. A rough and impure metal surface is more susceptible to corrosion because it provides more surface area for the reaction to occur. Additionally, the composition of the metal surface can also affect corrosion, as metals like aluminum and stainless steel form protective oxide films that prevent further destruction.
