INDIAN GEOGRAPHY

Detailed explanation-1: -Complete answer: The soil formed by the deposition of silt which are brought by rivers is known as alluvial soil.

Detailed explanation-2: -Alluvial soil is formed from the sediments deposited by the rivers in Indo-Gangetic plains and by sea waves in the coastal plains. It is very fertile and hence, excellent for agriculture. This soil is found extensively in the northern plains and other river valleys in India.

Detailed explanation-3: -Alluvial Soils: formed by the deposition of sediments by rivers.

Detailed explanation-4: -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. Alluvial soils are soils deposited by surface water along rivers, in floodplains and deltas, stream terraces, and areas called alluvial fans.

Detailed explanation-5: -Alluvial soil is formed by the deposition of sediments carried by rivers starting from the mountains (its origin). When the river overflows, this soil is deposited on the riverbanks. These soils differ from many other soils in that they are formed through a long process of rock transformation that can take millennia.
