write 5 sentences about Ganga and bramhaputra plain
Answers
Known as the second largest hydrological region in the world, the Ganga-Brahmaputra basin is also one of the oldest nurturers of people in the Indian subcontinent. The basin is one of the finest examples of the human’s interaction with the environment. Mapped in the northern half of the Indian subcontinent this basin of Ganga river and Brahmaputra river is the mother of many generations.
Answer:
The Ganga–Brahmaputra Plains represent a sediment-filled foreland basin in front of the Himalaya. Characterized by disparate physigraphic units and occurring as large terraces at different elevation levels belonging to different chronological times of the Late Quaternary epoch, the Plains conceal under the thick pile of fluvial and alluvial sediments a number of very high NE–SW-trending basement ridges delimited by long, deep faults. Continual and episodic differential movements on these faults with an attendant rise and subsidence of ground caused the persistent shifting of the rivers of the Yamuna and Ganga systems eastwards and of the Gandak–Kosi and Brahmaputra systems westwards. The neotectonic movements also brought about drainage obstruction, culminating in the development of swamps, marshes, lakes, and waterlogging in the much-faulted Kosi–Gandak domain as well as in northern Bangladesh. The abandonment by the Brahmaputra River of its former course and joining with Ganga River in Bangladesh was a result of tremendous neotectonic resurgence in the Bengal Basin. Palaeoseismites in the foothill belt all along the length of the Ganga–Brahmaputra plains point to the havoc wreaked by many seismogenic faults that riddle the northern periphery of the Ganga–Brahmaputra Plains.
