Formation of an iron oxide layer on a rock surface indicates which process?

Answer and explanation

Correct answer: Oxidation

Oxidation occurs when iron-bearing minerals react with oxygen to form iron oxides. This commonly produces a reddish-brown, rust-like coating or staining on a rock surface, so option B is correct. Carbonation mainly involves carbon dioxide dissolved in water acting on carbonate minerals, whereas exfoliation is a form of physical weathering. Exam tip: A rust-like red-brown coating on rock is a key clue for oxidation.
