The Himalayan Mountains

The correct answer is A, between the Satluj and Kali rivers. For regional divisions of the Himalayas, the Kumaon Himalaya is identified as the section between the Satluj in the west and the Kali in the east. This is a location-based regional classification, so the names of the boundary rivers are the key facts. B is incorrect because the Ganga and Godavari are not the accepted pair for delimiting Kumaon Himalaya; they are also widely separated drainage systems. C and D contain rivers from other parts of the Indian subcontinent and do not mark this Himalayan section. Read the question carefully: it asks for the rivers between which the region lies, not for rivers flowing through every part of Kumaon. Memory cue: Kumaon is bracketed by Satluj and Kali.

The direct answer is B: the Himalayas are relatively young mountains formed by folding. A fold mountain forms when large rock layers are compressed by the movement of tectonic plates. The Indian Plate moved northward and collided with the Eurasian Plate. Sedimentary layers were compressed, folded and uplifted, producing the Himalayan mountain system. They are called young because this formation occurred relatively recently in geological time, and uplift and earthquakes still show that the region remains active. Option B contains both essential ideas. Option A is wrong because marine coral does not form the Himalayan mountain chain. Option C is wrong because river deposits form alluvial plains, not these high folded ranges. Option D is wrong because the Himalayas are not old, stable plateaus. Memory cue: plate collision + compression + folding = young fold mountains.

The Himalayan extent is considered from the Indus to the Brahmaputra. Exam tip: treat these rivers as Himalayan extent markers.

The north to south order is Himadri, Himachal and Shiwalik. Exam tip: remember this order firmly.

Himadri is the Great Himalaya and contains high peaks. Exam tip: treat Himadri as the highest range.

Direct answer: A, Himachal lies between Himadri and Shiwalik. The Himalayas are commonly described as three parallel ranges from north to south: Himadri or Greater Himalaya, Himachal or Lesser/Middle Himalaya, and Shiwalik or Outer Himalaya. Because Himachal occupies the middle position between the northern Himadri and southern Shiwalik, it is called the Middle Himalaya. A is correct. B is wrong because the Bay of Bengal is a water body, not Himachal. C is wrong because the Thar Desert is in western India. D is wrong because an Arabian Sea island is not a Himalayan range. Learn the order rather than memorising only one name. Memory cue: north-to-south order is Himadri, Himachal, Shiwalik.

The direct answer is B. Shiwalik is called the Outer Himalaya because it is the southernmost and outermost of the three main Himalayan ranges. From north to south, the usual order is Himadri or Greater Himalaya, Himachal or Lesser Himalaya, and Shiwalik or Outer Himalaya. Shiwalik lies closer to the plains, so it is the outer belt when viewed from the Himalayan interior toward India’s plains. Option A is wrong because the northernmost range is Himadri, not Shiwalik. Option C is wrong because Shiwalik is a Himalayan mountain range, not a sea island. Option D is wrong because it is not part of the Peninsular Plateau. Memory cue: “Outer” and “southern” point to Shiwalik.

The direct answer is A, Himadri. The Himalayan ranges are arranged broadly in parallel belts. Himadri, also called the Great Himalaya, is the northernmost major range and has the greatest average height among the main parallel ranges. The reasoning is: compare the principal ranges → Great Himalaya/Himadri is highest → Lesser Himalaya or Himachal is lower → Shiwalik is the outer and lowest range. Option A is correct because Himadri contains many of the highest Himalayan peaks. Option B, Himachal, is the middle or Lesser Himalayan range, so it is lower than Himadri. Option C, Shiwalik, consists of the outer foothills and has the least height among these main ranges. Option D, Purvachal, refers to the eastern hills and a bend or continuation of the Himalayan system; it is not the highest parallel range. Do not select an answer just because it is another Himalayan name. Memory cue: highest Himalayan range = Great Himalaya = Himadri.

Kashmir Kangra and Kullu valleys are linked with Lesser Himalaya or Himachal. Exam tip: remember Himachal for valley clues.

Direct answer: A, Himachal. Pir Panjal and Dhauladhar are important ranges of the Lesser Himalaya, also called Himachal or the Middle Himalaya. The three main parts should be kept distinct: Himadri is the highest and northernmost range; Himachal lies south of it and contains ranges such as Pir Panjal and Dhauladhar; Shiwalik is the outer and southernmost range; Purvachal refers to the eastern hills and not these ranges. Therefore A is correct. B is wrong because Shiwalik is a separate outer range. C is wrong because Himadri is the Greater Himalaya. D is wrong because Purvachal is the eastern extension of Himalayan hills. Memory cue: Pir Panjal and Dhauladhar belong to the middle belt—Himachal.

Dun valleys are found between Himachal and Shiwalik. Exam tip: remember Dehra Dun as an example.

Dehra Dun is a famous example of a Dun valley. Exam tip: place Duns between Shiwalik and Himachal.

Shiwalik is an outer range made of relatively unconsolidated deposits. Exam tip: connect Shiwalik with recent deposits.

The core of Himadri is considered linked with granite. Exam tip: remember the hard core structure of Himadri.

The Himalayas are wider in the west and narrower in the east. Exam tip: remember width decreases from Kashmir towards Arunachal.

The Himalayas are also divided into regions between rivers. Exam tip: remember regional names through river boundaries.

Punjab Himalaya is considered between Indus and Satluj. Exam tip: connect Punjab Himalaya with western river boundaries.

Correct answer: C, Satluj and Kali. The Himalayas are divided into regional sections using important rivers as boundaries. In the usual west-to-east regional classification, the Punjab Himalaya lies between the Indus and Satluj, the Kumaon Himalaya lies between the Satluj and Kali, the Nepal Himalaya lies between the Kali and Teesta, and the Assam Himalaya lies between the Teesta and Dihang. Therefore, when the two boundary rivers are Satluj on the west and Kali on the east, the section is Kumaon Himalaya. Option A is the Punjab Himalaya boundary, not Kumaon. Option B gives the boundaries of Nepal Himalaya, not Kumaon. Option C is correct because it gives the exact pair Satluj–Kali. Option D gives the boundaries of Assam Himalaya. Memory cue: “Satluj to Kali = Kumaon”; also remember that these river pairs are read from west to east.

Nepal Himalaya is considered between Kali and Teesta. Exam tip: remember Nepal Himalaya with Kali-Teesta.

Assam Himalaya is considered between Teesta and Dihang. Exam tip: connect Assam Himalaya with eastern river clues.

In the east the Himalayas turn south after the Brahmaputra bend and the hills are called Purvachal. Exam tip: connect Purvachal with the northeast.

Naga Manipur and Mizo hills are linked with Purvachal. Exam tip: treat northeastern hills as Purvachal.

Himachal is also called the Lesser Himalaya or Middle Himalaya. It lies between the Himadri in the north and the Shiwalik in the south, so it forms the middle parallel range. Option C describes the Shiwalik, the outer range south of Himachal. Exam tip: remember the north-to-south order: Himadri, Himachal, Shiwalik.

Himadri is the Great Himalaya and is considered the most continuous range. Exam tip: choose Himadri for both great and continuous clues.

Many famous hill stations are found in the Lesser Himalaya. Exam tip: remember Himachal for hill station clues.
