Question

Release of iron from primary minerals and their dispersal as coatings on soil particles to impart brown to red colour to soil particles is called:
(A) Braunification
(B) Ferruginisation
(C) Rubification
(D) Laterisation

• A. (A), (B) and (D) only.
• B. (B), (C) and (D) only.
• C. (A), (B) and (C) only.
• D. (A), (C) and (D) only.

Hint:

Processes related to iron often result in distinct red, brown, or yellow hues in soils.

Answer 1

The Correct Option is C

Braunification, Ferruginisation, and Rubification all involve iron oxide formation or deposition that imparts red to brown coloration in soils. Laterisation is more associated with intense weathering and leaching.
