Which weathering process produces kaolin from granite?

Question 24 asks about the weathering process that produces kaolin from granite. Kaolin is a clay mineral formed from the chemical breakdown of feldspar, a common mineral in granite. This process involves water reacting with the minerals, which is known as hydrolysis.

• A Carbonation: Reaction with carbonic acid, primarily affects carbonates.
• B Oxidation: Reaction with oxygen, affects iron-bearing minerals.
• C Hydration: Absorption of water into mineral structure without chemical change.
• D Hydrolysis: Chemical reaction with water, breaking down minerals like feldspar into clay minerals.

The correct answer is D.
