The Tarai region of the Northern plains supports luxurious growth of natural vegetation and varied wild life population. This is because and swampy conditions region here
Re-emerging rivers from Bhabhar flow in undemarcated channels here creating marshy
all fertile coarse load is deposited at Tarai region after rivers re-emerge from Bhabar
the Tarai region is crossed by large Himalayan rivers which regularly deposit silt and clay
Both 1 and 3
Explanation:
Bhabar is a narrow belt ranging between 8-10 km parallel to the Shiwalik foothills at thebreak-up of the slope. As a result of this, the streams and rivers coming from the mountainsdeposit heavy materials of rocks and boulders, and at times, disappear in this zone. South ofthe Bhabar is the Tarai belt, with an approximate width of 10-20 km where most of thestreams and rivers re-emerge without having any properly demarcated channel, thereby,creating marshy and swampy conditions known as the Tarai. This has a luxurious growth ofnatural vegetation and houses a varied wild life. The Terai is crossed by the large perennialHimalayan rivers Yamuna, Ganges, Sarda, Karnali, Narayani and Kosi that have each builtalluvial fans covering thousands of square kilometres below their exits from the hills.
