🔍 Key Concepts

• Dissimilar metals in contact (think of a battery: two different metals and a conductor/electrolyte) • Difference between simple rusting and a process that involves electrical current/ions moving between metals • How galvanic or electrochemical action causes one metal to deteriorate faster

💭 Think About

• Which choice specifically suggests that an electric/ionic process is involved when two different metals are joined by a conductor? • Does rust always require two different metals, or can it occur on a single piece of steel exposed to moisture and oxygen? • Which term best fits the idea of a small battery cell being formed between two unlike metals in a marine environment?

✅ Before You Answer

• Make sure the option you select clearly involves dissimilar metals and a current path/conductor. • Eliminate any choices that describe general surface wear or simple oxidation of iron (rust) only. • Confirm that the term you pick is commonly associated with galvanic action between different metals in seawater or a conductive environment.
