Similarly, the freeze-thaw cycle interacts with oxidation by opening cracks in the rock, allowing more water and oxygen to penetrate the material. This differential weathering causes the rock to weaken internally, leading to the granular disintegration known as spheroidal weathering, where boulders gradually round into spherical shapes.

Biological weathering involves the actions of lichen or plant roots. As the metal oxidizes, it expands, generating internal pressure that causes the surrounding concrete to crack and spall.
Oxidation is distinct because it is a chemical process that changes the fundamental composition of the rock. Reinforced concrete, a staple of modern construction, suffers when the iron rebar inside corrodes.

Visible Manifestations in Natural Stone Limestone and Sandstone Transformation While iron oxides often create the rust-colored hues associated with this weathering, oxidation affects a wide range of materials. Unlike mechanical breakdown, which crushes stone without changing its composition, oxidation creates entirely new compounds, often resulting in the dramatic color changes and surface disintegration observed on natural landscapes.
