Question

Which of the following is not concerned with the formation of laterite soil?

• A. Weathering of parent rock
• B. Dissolution of lime and silicates in water
• C. Settling of non-soluble layers on top
• D. Deposition of magnesium and silicates by rain

Answer 1

The correct option is D Deposition of magnesium and silicates by rain

Laterite soil is formed in the following way: Due to strong and prolonged rainfall, weathering of underlying parent rock takes place. Lime and silicates, which are water soluble, dissolve in rainwater and settle down in the lower layers. Non soluble iron and aluminium remain in the top layers.
