Question

Arrange the blocks in steps of formation of laterite soil.

• A. Weathering
• B. Lime dissolves
• C. Silicates settle
• D. Iron stays on top

Answer 1

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.
