    The Himalayan Mountains
• • The Himalayas are young and flexible in
  their geological structure unlike the rigid
  and stable Peninsular Block.
• • These mountains are tectonic in origin,
  dissected by fast-flowing rivers which are
  in their youthful stage.
• • Various landforms like gorges, V-shaped
  valleys, rapids, waterfalls, etc. are formed.
  Syntaxial Bends of the Himalayas
• ● Himalayas extend in the east-west
  direction from the Indus gorge in the west
  to the Brahmaputra gorge in the east and
  take sharp southward bends at these
  gorges. These bends are called syntaxial
  bends of the Himalayas.
• ● The western syntaxial bend occurs near
  the Nanga Parbat.
• ● The eastern syntaxial bend occurs near
  the Namcha Barwa
● The Himalaya Mountain Range can also be
classified on the basis of height and they are as
follow
• 1. The Trans-Himalayan range
• 2. The Great Himalayas(Himadri)
• 3.Lesser or Middle Himalayas (The Himanchal Range)
• 4. The Siwalik Range
             ● The Himalayas are wider in the west than in the east.
The Trans-Himalayan range (Tibetan Himalaya)
• Most of the part of this Himalayan range lies in the Tibet and hence
  also called Tibetan Himalaya.
• 1. Zaskar .
• 2. Karakoram range. (K2 / Godwin Austen is the second highest peak
• in the world and highest in the Indian Territory lies here. )
• 3. Ladakh
• 4. Kailash .
•
The Great Himalayas (Himadri)
• ● The highest range of the Himalayas.
• ● The peaks are perennially covered with snow due to the lofty
  heights (Hence Himadri ).
• ● Almost all the prominent Himalayan peaks lies in this range like Mt
  Everest, Kanchenjunga, etc.
• ● Famous glaciers like the Gangotri and the Yamunotri
• lie here.
LESSER OR MIDDLE HIMALAYAS
(THE HIMANCHAL RANGE)
• ● This range lies between the Shiwalik in the south and the Greater
  Himalayas in the north.
• ● Gentle slopes of the eastern part of this range are covered with
  dense forests.
• ● Local names = Pir Panjal in Jammu and Kashmir; Dhauladhar in
  Himachal Pradesh.
• ● Most of the hill towns or resort towns are located in Himachal
  range for example Shimla, Mussoorie, Nainital, Darjeeling etc.
Duns
• They are formed between Lesser Himalayas and Shiwaliks. These
• valleys are deposited with coarse alluvium brought down by
  Himalayan rivers. These are known as Dun in the west and Duara in
  the East.
• Dehra Dun, Patli Dun are some of the well-known Duns.
• Name of Shiwaliks Region
• Jammu Region - Jammu Hills
• Dafla, Miri, Abor and Mishmi Hills - Arunachal Pradesh
• Dundwa Range - Uttarakhand
• Himalayas can be divided into the following
  subdivisions:
• 1. Kashmir or Northwestern Himalayas
• 2. Himachal and Uttaranchal Himalayas (
  Kumao H.)
• 3. Darjiling and Sikkim Himalayas
• 4. Arunachal Himalayas
• 5. Eastern Hills and Mountains.
KASHMIR HIMALAYAS
• Major ranges: Karakoram, Ladakh, Pir Panjal, Zaskar and Dhaola Dhar
• • The Kashmir Himalayas are also famous for Karewa formations
  which are useful for the cultivation of Zafran , a local variety of
  saffron.
2. KUMAON HIMALAYAS
• ● Two distinct features of this region from the point of view of
  physiography are the 'shiwalik' and 'Dun‘ formations.
• ● The region is also known to have five famous Prayags (river
  confluences).
3. The Darjiling and Sikkim Himalayas
• • Known for its fast-flowing rivers such as Teesta, it is a region of high
  mountain peaks like Kanchenjunga and deep valleys.
• the ‘duar formations‘ are important, which have also been used for
  the development of tea gardens.
4. The Arunachal Himalayas
•.
• • Some of the important mountain peaks of the region are Kangtu
  and Namcha Barwa.
• Brahmaputra flows through a deep gorge after crossing Namcha
  Barwa. Some of the important rivers ar Kameng, Subansiri, Dihang,
  Dibang and Lohit.
• • An important aspect of the Arunachal Himalayas
  is the numerous ethnic tribal community inhabiting
  in these areas.
• • Some of the prominent ones from west to east
  are the Monpa, Daffla, Abor, Mishmi, Nishi and the
  Nagas.
• Most of these communities practise Jhumming. It is
• also known as shifting or slash and burn cultivation.
 5. The Eastern Hills and Mountains
• Part of Himalayan mountain system having their general
• alignment from the north to the south direction.
• • They are known by different local names. In the north, they are
  known as Patkai Bum, Naga hills, the Manipur hills and in the south
  as Mizo or Lushai hills.
• • The physiography of Manipur is unique by the presence of a large
  lake known as ‘Loktak‘ lake at the centre, surrounded by mountains
  from all sides.
• Mizoram which is also known as the ‘Molassis basin’ which is made
  up of soft unconsolidated deposits.
