Question

why is duricrust formed on laterite soil??​

Answer 1

Answer:

Laterites are reddish clay soils rich in insoluble minerals such as iron and aluminium (bauxite). The soluble minerals are leached away leaving insoluble minerals abundant in the soil. Laterites are weathering products. in fact, laterites can harden to form duricrust if exposed to air.
