Answers
Answer:
q1 answer : The northern plain of India is formed by three river systems, i.e. the Indus, the Ganga and the Brahmaputra; along with their tributaries.
q2: answer: The northern plains of India are densely populated because of the following reasons: They consist of large plain of alluvial soil and the deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years make this plain fertile.
q3answer: Northern Plains were formed by the sediments brought in by three major Himalayan rivers (Ganga, Indus and Brahamaputra) and their tributaries. When these rivers flowed through the Himalayas, they eroded rocks, transported and deposited the smaller fragments of rocks in the foothills of the Himalayas.
q4 answer: The Terai or Tarai (Hindi: तराई Nepali: तराइ) is a lowland region in northern India and southern Nepal that lies south of the outer foothills of the Himalayas, the Sivalik Hills, and north of the Indo-Gangetic Plain. This lowland belt is characterised by tall grasslands, scrub savannah, sal forests and clay rich swamps. In northern India, the Terai spreads from the Yamuna River eastward across Haryana, Uttarakhand, Uttar Pradesh, Bihar and West Bengal. The Terai is part the Terai-Duar savanna and grasslands ecoregion. The corresponding lowland region West Bengal, Bangladesh, Bhutan and Assam in the Brahmaputra River basin is called 'Dooars'.[1] In Nepal, the Terai stretches over 33,998.8 km2 (13,127.0 sq mi), about 23.1% of Nepal's land area, and lies at an altitude of between 67 and 300 m (220 and 984 ft). The region comprises more than 50 wetlands. North of the Terai rises the Bhabar, a narrow but continuous belt of forest about 8–12 km (5.0–7.5 mi) wide.
