Detailed explanation-1: -S1: Alluvial soil is formed from the sediments deposited by the rivers in the Indo-Gangetic plains.
Detailed explanation-2: -Alluvium (from Latin alluvius, from alluere ‘to wash against’) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit.
Detailed explanation-3: -Alluvial soil is also known as riverine soil because they are found in river basins and are formed when streams and rivers slow their velocity.
