Which one of the following is known as uplands of delta region?
Explanation
In the geography of the Ganga-Brahmaputra deltaic plain, specific terminology is used to describe the distinct landforms created by fluvial deposition. The deltaic plain is an extension of Khadar land, covering approximately 1.9 lakh sq km in the lower reaches of the Ganga River [1]. This region is characterized by a mix of old mud, new mud, and marshy tracts. Within this deltaic landscape, the elevated landforms or uplands are specifically referred to as 'Chars' [1]. These 'Chars' represent relatively higher ground compared to the surrounding depressions. Conversely, the low-lying, waterlogged, or marshy areas found between these uplands are known as 'Bils' or 'Beels' [1]. While 'Chars' are often used for settlement and cultivation due to their elevation above the frequent flood level, 'Bils' remain as permanent or seasonal wetlands [1].
