Landforms - Assam PCS Exam Notes

Three Geological divisions:

The peninsular block
The Himalayas and other Peninsular Mountains
Indo-Ganga-Brahmaputra Plain

Peninsualar block is made of gneisses (metamorphic) and granites (igneous).

Six physiographic divisions:

The Northern and North-eastern Mountains
The Northern Plain
The Peninsular Plateau
The Indian Desert
The Coastal Plains
The Islands

Northern and North-Eastern Mountains

Approximate length of the Great Himalayan range: 2500 KM. Width: 160-400 KM

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

Kashmir Himalayas

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.
Ranges: Great Himalayan Range, Lesser Himalayas (Dhaoladhar in HP and Nagtibha in Uttarakhand), Shivalik range
Pilgrimage: Gangotri, Yamunotri, Kedarnath, Badrinath, Hemkund Sahib and the five famous prayags (Refer to Panch Prayag)
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.

Arunachal Himalayas

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:

Bhabar
Tarai
Alluvial Plains (Khadar and Bangar)

Bhabar

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.

Tarai

South of Bhabar. 10-20 KM wide.
Rivers re-emerge and create marshy and swampy conditions known as Tarai.

Alluvial Belt

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.

Peninsular Plateau

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

Deccan 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.

Central Highlands

Bounded by the Aravali and Satpura range.
Relic mountains, highly denuded and form discontinuous ranges.
Near Jaisalmer it is covered by the longitudinal sand ridges and crescent-shaped sand dunes called barchans.
Elevation: 700-1000 m
Banas, a tributary of Chambal, originates in the Aravalli. Other tributaries of Yamuna originate from the Vindhyan and Kaimur ranges.
Minerals in Chotanagpur plateau.

Northeastern Plateau

Extension of the main Peninsular plateau.
Meghalaya and Karbi Anglong plateau.
Megahalaya plateau: Garo hills, Khasi hills and Jaintia hills (named after the tribals inhabiting the region)
Rich in minerals like coal, iron, sillimanite, limestone and uranium.
Receives maximum rainfall from SW monsoon. Hence, Meghalaya plateau has a highly eroded surface. Cherrapuni and Myswarnam.

Indian Desert

Aka Marusthali
Northwest of the Aravali hills
Dotted with longitudinal dunes and barchans.
Low rainfall: >150 mm per year Low vegetation cover
Evidence that this area was under the sea during the Mesozoic era.
Features: mushroom rocks, shifting dunes and oasis.
Rivers are ephemeral: Luni. Brackish lakes. Inland drainage.

Coastal Plains

Two divisions:

Western coastal plains
Eastern Coastal Plains

Western Coastal Plains

Submerged coastal plain. Hence, a narrow belt. Narrow in middle and broader towards north and south.
Ports: Provides natural conditions for the development of ports and harbours due to submergence. Kandla, Mazagaon (Mumbai), JLN port Navha Sheva, Maramagao, Mangalore, Cochin etc.
Mumbai has the world’s largest natural harbour.
May be divided into: Kachchh and Kathiawar coast in Gujarat, Konkan coast, Goan coast and Malabar coast.
Rivers don’t form delta.
Kayals (Backwaters): Found in the Malabar coast. Used for fishing and inland navigation. Every year Nehru Trophy Vallamkali (boat race) is held in Punnamada Kayal in Kerala.

Eastern Coastal Plains

Broader
Emergent coast. Hence, less number of ports and harbours. Chennai, Vizag, Paradwip, Haldia.
Delta formation

The Islands

Two major Divisions:

Andaman and Nicobar
Lakshwadeep & Minicoy

Andaman and Nicobar
