Question

formation of alluvial soil

Answer 1

Alluvial soil is the main and important soil that spreads across the river plains. .They are formed by deposition of materials or sediments (alluvium) brought in down by rivers that consist of silt, sand, clay, etc.

Alluvium consists of silt, sand, clay, and gravel and often contains a good deal of organic matter. It therefore yields very fertile soils such as those of the deltas of the Mississippi, the Nile, the Ganges and Brahmaputra, and the Huang rivers. Alluvial soils are widespread.
