INDIAN GEOGRAPHY

Detailed explanation-1: -The correct option is A Alluvial. The Himalayan river systems deposited large amounts of soil in the northern plains over a large period of time called Alluvial soil. This soil is found extensively in the northern plains and other river valleys in India.

Detailed explanation-2: -alluvium, material deposited by rivers. It is usually most extensively developed in the lower part of the course of a river, forming floodplains and deltas, but may be deposited at any point where the river overflows its banks or where the velocity of a river is checked-for example, where it runs into a lake.

Detailed explanation-3: -Montane type of soil is found in Himalayan region. Montane Soils characteristics are sandy loam and clay, with a development of a thin “mor” layer on the ridge.

Detailed explanation-4: -Alluvial soil is also known as riverine soil because it is found in river basins and is formed when the velocity of streams and rivers slows. Alluvial soil is formed by the deposition of sediments carried by rivers starting from the mountains (its origin).
