Trans/Tibet Himalaya

  • Located in the north.
  • Karakoram, Ladakh, Zaskar, Kailash mountain ranges are located.
  • The Karakoram range is called the Backbone of High Asia.
  • The Indus river cuts across the Ladakh range to form the Bunzi Gorge.
  • Godwin Austin (K2), India’s highest peak, is in the Karakoram range.
  • Important Glaciers – Valtero and Viapho (in Shigar Valley), Siachen (in Nubra Valley).
  • Origin of rivers- Brahmaputra, Indus, Sutlej.
  • Due to the cold tropical climate, there is a complete lack of vegetation on it.

Himalayan Mountain range

  • It is one of the world’s new folded mountains, which is mainly made up of layered rocks.
  • It was built in the Tertiary period.
  • This mountain extends from Nanga Parbat (Jammu) in the west to Namcha Barwa (Arunachal Pradesh) in the east. [Mountainous Region of India]
  • Since the Carboniferous period, Peninsular India has been moving north and northeast continuously, resulting in the collision of the Indian-Australian Plate with the Eurasian Plate, which is moving south at a relatively slow rate.
  • The collision of these two plates put pressure on the deposits of the Tethys Sea located between them, which resulted in the origin of the Himalayas.
  • Since the Indian-Australian plate is still in motion, this is the reason why the uplift of the Himalayas continues even at the present time.
  • The Himalayas are tectonic (folded) mountains.
  • The rise of the Himalayas was completed in three phases, resulting in the formation of three clear ranges, where the Himalayas are presently there, about 7 crore years ago, the Great Himalaya was formed in the Oligocene period, located in the form of the Tethys Sea and parallel to the Himalayas in the south. A trough was also formed which was later filled by the deposits brought by the Himalayan rivers. Thus, due to the earth movement of the Miocene period, the middle Himalayas were formed in the second phase. The last rise of the Himalayas took place in the Pliocene period. The rise of this third phase resulted in the formation of the Shivalik Himalayas.
  • Thus the Himalayas is a tectonic (folded) mountain, its uplift has been completed in 3 phases, resulting in the formation of three clear ranges:
    • The great Himalayas
    • Middle Himalayas
    • Shivalik Himalaya

Greater Himalayas (Interior / Himadri)

  • The ancient Indo-Brahma river used to flow where Shivalik is today. The Shivalik Himalayas originated from the melting of sediments deposited in the valley of this river.
  • Between the Shivaliks and the Lesser Himalayas, there are many subsidies such as the Kathmandu Valley. In the West, they are called Doons.
  • Famous doons are- Dehradun, Kotli Doon, and Patlidoon.

  • The highest peak of Mizo Hill is the Blue Mountains. Uttar Bharat Ka Parvatiya Kshetra
  • The hills of Purvanchal provide direction to the Indian monsoon.
  • These hills act as a water divider as well as a climate divider.

Territorial classification of Himalayas

In addition to this north-south, the Himalayas are also divided on the basis of regions located from west to east. These classifications have been done on the basis of the boundaries of river basins.
