Correct option is A
The correct answer is (A) Chemical weathering
Explanation:
• Chemical weathering leads to leaching of soluble minerals.
• It concentrates insoluble minerals like aluminium oxides.
• Bauxite forms through lateritisation in tropical climates.
• Process is dominant in warm and humid regions.
Information Booster:
• Laterite soils are rich in iron and aluminium.
• Chemical weathering aids supergene enrichment of ores.
Additional Knowledge (Incorrect Options):
(b) Biological weathering
• Involves plants and organisms, not ore enrichment.
(c) Glacial weathering
• Dominant in cold regions, not bauxite formation.
(d) Mechanical weathering
• Breaks rocks physically without mineral concentration.
