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 framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
