Which risk increases when copper sheathing used on wooden ships experiences prolonged immersion in seawater containing dissolved sulfides?

💡 Explanation

When copper sheathing is exposed to seawater with dissolved sulfides, crevice corrosion happens because the sulfide ions react with the copper, generating copper sulfide and consuming oxygen faster in the crevices. Therefore crevice corrosion is most likely because oxygen depletion creates a electrochemical potential difference, rather than galvanic or stress corrosion which involve different environmental-material interactions.
