Answer
(i) Black soil is also called lava soil because it is formed by the denudation of volcanic rocks.
(ii) Red soil is red in colour as it contains large amounts of iron oxide. At several places, its colour changes and it appears brown or grey. It looks yellow when it occurs in a hydrated form.
(iii) Jute is cultivated in West Bengal because the alluvial soil found in West Bengal is very fertile and supports jute cultivation.

The load of the rivers such as Ganga-Brahmaputra, comprising sand, silt and gravels, is tremendous. This gets deposited in the deltas or the lower course of river over a long period forming river islands. These islands can be temporary or permanent because they may also disappear when the volume of river water or its speed increases. Majuli, Assam, in the Brahmaputra is a permanent riverine island which is rich in biodiversity.
Chars in Bangladesh are mostly islands formed in large deltas of the Ganga-Brahmaputra system. Mostly these islands are not permanent as they last as long as the river is full of sediments and is slow. What do you think is the land use in chars?
