Question

Chemical weathering involving complete disintegration or modification in structure and composition of primary minerals is –

• A. Hydration
• B. Oxidation
• C. Hydrolysis
• D. Carbonation

Hint:

Hydrolysis alters minerals most thoroughly—especially silicates like feldspar into clay.

Answer 1

The Correct Option is C

Hydrolysis is the most significant chemical weathering process, where hydrogen ions replace metal ions in minerals, leading to complete structural and compositional changes.
