There was hardly any free oxygen in the atmosphere back then.
Chemical weathering can be caused by factors such as exposure to water, oxygen, carbon dioxide, and acids. Common processes that contribute to chemical weathering include hydrolysis, oxidation, and carbonation. Additionally, the presence of certain minerals or vegetation can accelerate chemical weathering.
Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces. Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
the most common oxidation number for oxygen is -2.
Cobalt is a transition metal. Its oxidation states are 2 (3).
Chemical weathering is more common in deserts, as the dry conditions limit the amount of mechanical weathering that can occur. Chemical weathering processes such as oxidation, hydration, and dissolution are more prevalent in desert environments where water is scarce.
Chemical weathering examples include the breakdown of rocks through processes like oxidation, hydrolysis, and dissolution. For example, the formation of rust on iron-rich rocks is a result of oxidation. The dissolution of limestone by acidic rainwater is another common example of chemical weathering.
Both oxidation and hydrolysis are chemical weathering processes that break down rocks and minerals. Oxidation involves the reaction of minerals with oxygen, while hydrolysis involves the reaction of minerals with water. Both processes contribute to the breakdown of rocks over time through chemical reactions.

Yes. Rust seen in a rock is an example of an iron bearing mineral oxidizing and chemically weathering the rock.

facts about weathering
Florida typically experiences chemical weathering due to its warm and humid climate. The abundant rainfall and high temperatures promote the breakdown of rocks and minerals through chemical processes like hydrolysis and oxidation. This type of weathering is common in tropical regions like Florida.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Physical weathering physically breaks down the rock, whereas chemical weathering breaks down the rock through chemical changes. For example, physical weathering could break down rock through ice wedging, which occurs when water seeps through the cracks in the rock, freezes, and expands, causing the rock to crack. Chemical weathering could be when oxidation (rusting) occurs, when metal is exposed to water and oxygen. Either way they both break down rock.
Oxygen can combine with certain minerals in rocks through oxidation, leading to chemical weathering. This process can weaken the rock structure and cause it to break apart over time. This is particularly common in minerals such as iron, which can rust when exposed to oxygen.
The most common cause of chemical weathering is oxygen
