Question

what are the river islands called​

Answer 1

Answer:

River/riverine island is a landmass formed within a river. They're often formed by the changing course of a river, especially if the river meanders. World's largest river island is Majuli, in the Brahmaputra river in Assam. Majuli is subject to erosion by the Brahmaputra — which means a shrinking Majuli.
