Here's how it works:
* Iron in Rocks: Many rocks contain iron minerals.
* Reaction with Oxygen: When these minerals are exposed to oxygen in the air or water, the iron atoms react with the oxygen.
* Formation of Iron Oxide: This reaction creates iron oxide, which is a reddish-brown compound commonly known as rust.
* Weakening of the Rock: The formation of rust weakens the rock structure, making it more susceptible to further weathering and erosion.
This is just one example of how oxygen can weather rocks. There are other processes like hydrolysis and carbonation that also involve oxygen and contribute to rock weathering.
