Which process is an important part of chemical weathering through oxidation?

-oxygen giving up electrons to other elements.
-oxygen capturing electrons from other elements.
-oxygen capturing protons from other elements.
-oxygen giving up protons to other elements.

The process that is an important part of chemical weathering through oxidation is oxygen giving up electrons to other elements.

Explanation:

A loss of electrons by the molecules in a chemical reaction is known as oxidation. It happens during the increase of oxidation state of an atom, molecule or an ion. When there is a gain in the electrons of a molecule it is known as reduction. The process of oxidation causes the formation of rust.

In chemical weathering, when the substance or particles that present in a rock that contains iron,  reacts with oxygen, it forms rust in it. Hence some of the rocks looks reddish brown in color. These rocks when oxidized form rust in it and becomes very weak. It can be easily broken down into pieces.

the correct answer is b
