Impact of Himalayas on the climate of India?
It can be divided into five sub-divisions:
- Kashmir (or Northwestern) Himalayas
- Himachal and Uttaranchal Himalayas
- Darjeeling and Sikkim Himalayas
- Arunachal Himalayas
- Eastern Hills and Mountains
- Ranges: Karakoram, Ladhakh, Zaskar, Pir Pinjal
- Glaciers: Baltoro, Siachen

- Lakes: (freshwater) Dal and Wular; (saltwater) Pangong Tso and Tso Moriri
- Pilgrimage: Vaishno Devi, Amarnath Cave, Charar-e-Sharif
- They are also famous for Karewa formations which are useful for the cultivation of Zafran (a local variety of Saffron). Karewas are the thick deposits of glacial clay and other materials embedded with moraines.
- Kashmir is located on the banks of Jhelum river.
- Meanders is a typical feature associated with the rivers in this region.
- In South, there are longitudinal valleys called duns; Jammu dun and Pathankot dun
Himachal and Uttarakhand Himalayas
- Lies between rivers Ravi and Kali
- Drained by two major river systems: Indus and Ganga
- Northernmost part is an extension of the Ladakh desert, lies in Spiti.

- Famous for hill stations: Dharamshala, Mussoorie, Shimla, Kaosani; Cantt.: Kasauli, Almora, Lansdowne, Ranikhet
- The important distinguishing features of this area are the ‘Shivalik’ and ‘Dun formations’.
- Important duns: Chandigarh-Kalka, Nalagarh, Dehra, Harike, Kota
- Dehradun is the largest of all duns: Length – 35-45 KM, Width: 22-25 KM
- Inhabited with the Bhotia They migrate to higher reaches (Bugyals) in summer and return to the valleys during winters.
Darjeeling and Sikkim Himalayas
- Between Nepal Himalayas and Bhutan Himalayas.
- Fast flowing rivers such as Tista
- Peaks: Kanchenjunga
- Tribe: Lepcha
- Has a mixed population of Nepalis, Bengalis and tribals from Central India.
- Importance: Due to the moderate slope, it is best suited for tea plantations. <India produces about 26 pc of tea in the world; second after China. Also, accounts for 12 pc of tea exports; fourth in the world.>
- Duar formations are peculiar to this region.
- From Bhutan Himalayas to Diphu pass in the east.
- Direction: Southwest to Northeast
- Peaks: Kangtu and Namya Barwa
- Rivers: Brahmaputra, Kameng, Subansiri, Dihang, Dibang and Lohit.
- These rivers are perennial and have the highest hydro-electric power potential in the country.
- Tribes: Monpa, Daffla, Abor, Mishmi, Nishi and Nagas
- These communities practice shifting cultivation known as Jhumming.
Eastern Hills and Mountains
- Direction: North to South
- Ranges: Patkai Bum, Naga hills, Manipur hills, Mizo or Lushai hills
- These are low hills
- Tribes practice Jhum cultivation
- Rivers: Barak. Most of the Nagaland rivers form a tributary of Brahmaputra. Rivers in eastern Manipur are the tributaries of Chindwin, which in turn is a tributary of the Irrawady of Myanmar.
- Lake: Loktak
- Loktak Lake: is an important lake in Manipur which is surrounded by mountains on all sides. It is the largest freshwater lake in northeastern India. Also called the only Floating Lake in the world due to floating masses of organic matter on it. It serves as a source for hydropower generation, irrigation and drinking water supply.
- Keibul Kamjao National Park located in the Bishnupur district of Manipur is the only floating park in the world and is an integral part of the Loktak Lake. Home to the endangered Manipur Eld’s Deer or Brow-antlered Deer or Sangai or Dancing Deer.
- Mizoram is also known as the ‘Molassis basin’ which is made up of soft unconsolidated deposits.
The Northern Plains
- Formed by the alluvial deposits of rivers – Indus, Ganga and Brahmaputra.
- Length: 3200 KM; Width: 150-300 KM
Three main zones:
- Alluvial Plains (Khadar and Bangar)
- Narrow belt. 8-10 KM wide.
- Paralllel to Shivalik at the break-up of the slope. Hence, streams and rivers deposit heavy rocks (and at times disappear) in this zone.
- South of Bhabar. 10-20 KM wide.
- Rivers re-emerge and create marshy and swampy conditions known as Tarai.
- South of Tarai.
- Features of mature stage of fluvial erosional and depositional landforms such as sand bars, meanders, ox-bow lakes and braided channels. Riverine islands in Brahmaputra.
- Brahmaputra takes a turn an almost 90 degree turn at Dhubri (Assam) before entering Bangladesh.
- Bounded by the Delhi ridge, Rajmahal Hills, Gir range and Cardamom hills.
- Made up of a series of patland plateaus: Hazaribagh, Palamu, Ranchi, Malwa, Coimbatore, Karnataka etc.
- One of the oldest and most stable landmass of India.
- Physiographic Features: Tors, block mountains, rift valleys, spurs, bare rocky structures, hummocky hills and quartzite dykes offering natural sites for water storage.
- Black soil in western and northwestern parts.
- Bhima fault in this region has frequent seismic activity (Lathur earthquake)
- NW part also has ravines and gorges: Chambal, Bhind and Morena.
Three broad regions:
- Deccan Plateau
- Central Highlands
- Northwestern Plateau
- Bordered by Eastern Ghats, Satpura, Maikal range and Mahadeo hills
- Important ranges: WG: Sahyadri, Nilgiri, Anaimalai and Caradamom hills; EG: Javadi hills, Palconda range, Nallamala Hills, Mahendragiri hills
- EG and WG meet at Nilgiri hills.
- Highest peak: Anaimudi (2695 m) on Anaimalai hills; Dodabetta (2637 m) on Nilgiri hills.
- Rivers: Mahanadi, Godavari, Krishna, Kaveri etc.
