What is known as oxidation?

उत्तर
Oxidation is a type of chemical weathering that occurs when minerals, especially those containing iron, react with oxygen in the air or water. This chemical reaction forms iron oxide (commonly known as rust), which weakens the rock and causes it to break down. Oxidation is commonly seen in rocks containing iron-rich minerals like haematite and magnetite, and it leads to the disintegration of rocks over time.
