🇬🇧 Corrosion meaning: English Vocabulary Flash Card

Corrosion is what happens when metal slowly gets eaten away and damaged, usually by water and air. Over time, shiny metal can turn rough, flaky, and rusty. It’s like the metal is being ‘chewed up’ by tiny reactions with its surroundings, so the metal becomes weaker and can even get holes in it.
