The process is oxidation (a form of chemical weathering).

Oxidation occurs when oxygen reacts with minerals (especially iron-bearing ones), converting Fe2+ to Fe3+ and forming iron oxides/hydroxides (rust). This changes the rock’s composition, color (reddening or yellowing), and weakens the rock (helps break it down into soil).
