How does oxidation weather rocks?

Question

The addition of electrons causes the rock to weaken.
The removal of electrons causes the rock to weaken.
The formation of rust strengthens the minerals in rock.
The internal pressure from oxygen causes rocks to crack.

Answer 1

Oxidation weathering primarily involves the removal of electrons from minerals within the rocks, often associated with the reaction of minerals with oxygen. This process alters the mineral structure and can lead to the weakening of the rock.

Therefore, the correct statement is:

The removal of electrons causes the rock to weaken.

This process often results in the formation of oxides or hydroxides, which can be less stable than the original minerals, contributing to the breakdown and weathering of the rock.
