प्रश्न
Alluvial Soils are also called ‘Riverine Soils’. Why?
उत्तर
The chief region of Alluvial Soils in India is the Indo-Gangetic plain, where Alluvial Soils have been deposited mostly by rivers. The coastal belts are the areas of alluvium. The deltaic alluvium on the eastern coast has also been deposited by river-channels. Therefore, Alluvial Soils are rightly called Riverine Soils.
