  The Himalayas, geologically young and structurally fold mountains stretch over the Northern borders of India. These mountain ranges run in a West-East direction from the Indus to the Brahmaputra. The Himalayas represent the loftiest and one of the most rugged mountains barriers of the world. They form an arc, which covers a distance of about 2400 km. Their width varies from 400 km in Kashmir to 150 km in Arunachal Pradesh. The altitudinal variations are greater in the Eastern half then those in the Western half. The Himalayas consists of three parallel ranges in its longitudinal extent. A number of valleys lie between these ranges. The Northern-most range is known as the Great or Inner Himalayas or the Himadri. It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres. It contains all prominent Himalayan peaks.

  Read the source and answer the following questions.

  The Northern Plain is broadly divided into three sections. The Western part of the Northern Plain is referred to as the Punjab Plains. Formed by the Indus and its tributatries, the larger part of this plain lies in Pakistan. The Indus and its tributaries - the Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalaya. This section of the plain is dominated by the doabs. Doab' is made up of two words - 'do' meaning two and 'ab' meaning water. Similarly 'Punjab' is also made up two words -'Punj' meaning five and 'ab' meaning water.

  The Ganga plain extends between Ghaggar and Teesta rivers. It is spread over the states of North India, Haryana, Delhi, Uttar Pradesh, Bihar, partly Jharkhand and West Bengal to its East, particularly in Assam lies the Brahmaputra plain. The Northern plains are generally described as flat land with no variations in its relief. It is not true. There vast plains also have diverse relief features. According to the variations in relief features, the Northern plains can be divided into four regions. The rivers, after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks. It is known as bhabar. All the streams disappear in this bhabar belt. South of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as Terai. This was a thickly forested region full of wildlife. The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition.

  Read the source and answer the following questions.

  The folds of the Great Himalayas are asymmetrical in nature. The core of this part of Himalayas is composed of granite. It is perennially snow bound and a number of glaciers descend from this range. The range lying to the South of the Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya. The ranges are mainly composed of highly compressed and altered rocks. The altitude varies between 3,700 and 4,500 metres and the average width is of 50 km. While the Pir Panjal range forms the longest and the most important range, the Dhaula Dhar and the Mahabharat ranges are also prominent ones.

  This range consists of the famous valley of Kashmir, the Kangra and Kullu valley in Himachal Pradesh. This region is well-known for its hill stations. The outer-most range of the Himalayas is called the Shiwaliks. They extend over a width of 10-50 km and have an altitude varying between 900 and 1100 metres. These ranges are composed of unconsolidated sediments brought down by rivers from the main Himalayan ranges located farther North. These valleys are covered with thick gravel and alluvium. The longitudinal valley lying between lesser Himalaya and the Shiwaliks are known as Duns. Dehra Dun, Kotii Dun and Path Dun are some 3f the well-known Duns.

  Read the source and answer the following questions.

  Besides the longitudinal divisions, the Himalayas have been divided on the basis of regions from West to East. These divisions have been demarcated by river valleys. For example, the part of Himalayas lying between Indus and Satluj has been traditionally known as Punjab Himalaya, but it is also known regionally as Kashmir and Himachal Himalaya from West to East respectively. The part of the Himalayas lying between Satluj and Kali rivers is known as Kumaon Himalayas. The Kali and Teesta rivers demarcate the Nepal Himalayas and the part lying between Teesta and Dihang rivers is known as Assam Himalayas. There are regional names also in these broad categories.

  The Brahmaputra marks the Eastern-most boundary of the Himalayas. Beyond the Dihang gorge, the Himalayas bend sharply to the South and spread along the Eastern boundary of India. They are known as the Purvachal or the Eastern hills and mountains.

  These hills running through the North-Eastern states are mostly composed of strong sandstones, which are sedimentary rocks, covered with dense forests, they mostly run as parallel ranges and valleys. The Purvachal comprises the Patkai hills, the Naga hills, the Manipur hills and the Mizo hills.

  Read the source and answer the following questions.

  The Northern plain has been formed by the interplay of the three major river systems, namely the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division. With a rich soil cover combined with adequate water supply and favourable climate, it is agriculturally a productive part of India.

  The rivers coming from Northern mountains are involved in depositional work. In the lower course, due to gentle slope, the velocity of the river decreases, which results in the formation of riverine islands. Majuli, in the Brahmaputra river, is the largest inhabited riverine island in the world. The rivers in their lower course split into numerous channels due to the deposition of silt. These channels are known as distributaries.

  A)
