Detailed explanation-1: -Oxidation. The most common example of oxidation is when rust occurs on iron. Oxidation occurs when oxygen reacts with metal elements in rock or on other surfaces creating oxides. This process weakens the structure of the materials, often producing a reddish-brown color.

Detailed explanation-2: -Another type of chemical weathering works on rocks that contain iron. These rocks turn to rust in a process called oxidation. Rust is a compound created by the interaction of oxygen and iron in the presence of water. As rust expands, it weakens rock and helps break it apart.

Detailed explanation-3: -Chemical Weathering by Oxygen The most familiar type of oxidation is when iron reacts with oxygen to create rust. Minerals that are rich in iron break down as the iron oxidizes and forms new compounds. Iron oxide produces the red color in soils.

Detailed explanation-4: -Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

Detailed explanation-5: -Oxidation is the reaction of rock minerals with oxygen, thus changing the mineral composition of the rock. When minerals in rock oxidize, they become less resistant to weathering. Iron, a commonly known mineral, becomes red or rust colored when oxidized.
