Question

Which of the following best explains why soils derived from basaltic parent material in high-rainfall tropical regions of India tend to develop into laterite soils that are rich in iron and aluminium sesquioxides but poor in silica, over long periods of intense weathering?

A Salinization, a process in which soluble salts accumulate at the surface
B Podzolization, a process restricted to cold, coniferous forest regions
C Desilication, a process in which silica is preferentially leached out while sesquioxides accumulate
D Calcification, a process in which calcium carbonate accumulates in the profile
E Gleization, a process associated with waterlogged, oxygen-deficient conditions
