Which of the following statements accurately describes the geographical distribution and genesis of laterite soils in India?
A. They are formed in arid regions through wind deposition of calcium carbonate nodules.
B. They develop in regions of high temperature and heavy rainfall with alternate wet and dry periods through intense leaching.✓ Correct Answer
C. They are found exclusively in river floodplains and are renewed annually by fresh silt deposition.
D. They originate from glacial outwash plains in high-altitude Himalayan valleys.
💡 Solution & Explanation
Laterite soils develop under tropical monsoon climates characterized by high temperatures and alternating wet and dry seasons, where heavy rainfall causes intense leaching of silica and soluble bases, leaving behind residual accumulations of iron and aluminum oxides. Arid regions contain desert soils with calcareous accumulations, whereas river floodplains feature fertile alluvial deposits. Glacial outwash plains contain rocky moraines and gravel terraces.
