Detailed explanation-1: -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. The surface color of Mars is also a good example of oxidation.

Detailed explanation-2: -Oxidation weathers rocks when they contain iron and the iron reacts with oxygen to form iron oxide. Iron oxide is not a strong substance so it weakens and easily breaks down. This oxidation process creates a red looking rock because iron oxide is a brownish-red color.

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -Oxidation is another kind of chemical weathering that occurs when oxygen combines with another substance and creates compounds called oxides. Rust, for example, is iron oxide.
