Important examples of corrosion in TOEIC

In TOEIC vocabulary questions, corrosion is often used to discuss material damage or wear.

Example of a confusing word: erosion (wearing away)

▪The bridge showed erosion after many years.
▪The bridge was worn away after many years.
"Corrosion" refers to the gradual destruction or damage of materials, usually metals, due to chemical reactions like oxidation, commonly seen as rust. In the sentence, "The bridge showed corrosion," it correctly describes the chemical wear on the bridge. "Erosion," however, refers to the process of being worn away by natural forces like wind or water, not chemical reactions. Therefore, using "erosion" in this context is incorrect because it implies a different type of wear. Thus, "corrosion" is the correct choice.
