INDIAN GEOGRAPHY

Detailed explanation-1: -In the lower course, due to gentle slope, the velocity of the river decreases which results in the formation of riverine islands. Due to Erosion activity in the upper reaches of Himalayan mountains, rivers carry the alluvial sediments. When deposited in the floodplains, forms the riverine islands.

Detailed explanation-2: -Riverine island is formed because of the deposition of mud and rocks in the river bed. River Brahmaputra while flowing across the north and northeastern part of the country is involved in depositional work. In the lower course, the speed of the river decreases leading to the formation of riverine islands.

Detailed explanation-3: -An island made by a river when it flows in braided channels is known as riverine island. Majuli is the largest inhabited riverine island in the world, made by the river Brahmaputra.

Detailed explanation-4: -Large river islands are formed when large rivers cut through hilly or uneven topography, leaving a large raised section of the landmass exposed. They can also be formed in places where a large amount sediment piles up higher than the water level.

Detailed explanation-5: -River islands are named river islands which develop in the river when the level descends down. The two rivers often interconnect each other to establish certain forms of islands. Complete answer: The island of Riverine is created by a river land mass.
