The idea in one minute

India has six physiographic divisions: the Himalayas, Northern Plains, Peninsular Plateau, Indian Desert, Coastal Plains and Islands. Exams ask about ranges, the highest peak of each group, passes by state and the biggest lake of each kind.

01

The six divisions

India is divided into six parts:

  1. The Himalayas
  2. The Northern Plains
  3. The Peninsular Plateau
  4. The Indian Desert
  5. The Coastal Plains
  6. The Islands

Start every "which division" question by placing the place in one of these six boxes.

02

The Himalayas

The Himalayas have three parallel ranges. From north to south they fall in height.

RangeAlso calledKey points
HimadriGreater / InnerHighest, about 6,000 m average; perennial snow; all 8,000-m peaks
HimachalLesser / MiddleWidest range; Shimla, Mussoorie, Nainital, Darjeeling; Pir Panjal, Dhauladhar, Mahabharat
ShiwalikOuterYoungest and lowest (900-1,100 m)

Duns are valleys between Himachal and Shiwalik. Examples: Dehradun, Kotli Dun, Patli Dun.

In the north-east the ranges bend south as the Purvanchal hills: Patkai Bum, Naga Hills, Manipur Hills and Mizo (Lushai) Hills.

Note: The Himalayas are among the youngest fold mountains. The Aravallis are the oldest fold mountains of India.

03

Mountain passes by state

Learn passes in groups, one state at a time.

  • Ladakh / J&K: Karakoram Pass (Ladakh to Xinjiang), Khardung La (Leh to Nubra valley), Zoji La (Srinagar-Kargil-Leh), Banihal (Jammu to Srinagar; Jawahar Tunnel under the Pir Panjal).
  • Himachal Pradesh: Rohtang (Kullu to Lahaul and Spiti; Atal Tunnel below it), Baralacha La (Manali-Leh road), Shipki La (the Sutlej enters India here).
  • Uttarakhand: Lipulekh (Kailash-Mansarovar route), Mana Pass (near Badrinath), Niti Pass.
  • Sikkim: Nathu La (India-China trade, reopened 2006), Jelep La (via the Chumbi valley).
  • Arunachal Pradesh: Bomdi La, Diphu Pass.
  • Western Ghats: Thal Ghat (Mumbai-Nashik), Bhor Ghat (Mumbai-Pune), Palghat (Palakkad) Gap between the Nilgiri and Anaimalai hills (Kerala-TN).
05

Plateau, ghats and coasts

The Peninsular Plateau is India's oldest landmass. It is made of hard crystalline rock.

  • Deccan Trap: basalt lava on the north-west edge; the source of black soil.
  • Chota Nagpur Plateau: the mineral storehouse.
  • Meghalaya Plateau (Garo-Khasi-Jaintia hills): split from Chota Nagpur by the Malda gap.
  • Western Ghats (Sahyadri): continuous and higher; a UNESCO World Heritage Site (2012).
  • Eastern Ghats: low and broken by rivers.

Tip: The Nilgiris, Anaimalai and Cardamom hills join the two Ghats.

West coast, north to south: Konkan, Kannad (Kanara), Malabar. Kerala's backwaters (kayals, e.g. Vembanad) lie here. East coast: Utkal / Northern Circars in the north and Coromandel in the south, with wide deltas.

Question types you will see

Each type: how to recognise it, the method step by step, and one question to try.

Type 1very common3 practice Q

Mountain pass and its state or route

How to spot it:

A pass name (Nathu La, Zoji La, Shipki La, Rohtang, Bhor Ghat) with states or linked places as options.

Method

  1. Group the pass by state: Ladakh, Himachal, Uttarakhand, Sikkim, Arunachal.

  2. For Ghat gaps: Thal (Mumbai-Nashik), Bhor (Mumbai-Pune), Palghat (Kerala-TN).

  3. Recall the extra fact: Shipki La (Sutlej), Rohtang (Atal Tunnel), Banihal (Jawahar Tunnel).

Why it works:

Passes are best learned as state groups, not as a long list.

Try this

Lipulekh Pass, used by pilgrims to Kailash-Mansarovar, is in which state?

Show solution

  1. Lipulekh belongs to the L-M group.

  2. That group is Uttarakhand.

  3. It lies on the India-Tibet border near the Nepal tri-junction.

Answer

Uttarakhand (Pithoragarh district)

Type 2very common3 practice Q

Peak superlatives and their range or state

How to spot it:

'Highest peak of South India / of the Aravallis / entirely within India', or a peak with states as options.

Method

  1. Recall the ladder: K2, Kangchenjunga, Nanda Devi.

  2. Recall range tops: Anamudi, Doddabetta, Guru Shikhar, Dhupgarh, Parasnath.

  3. Match the key word in the stem (range, state, 'entirely within') to the right row.

Why it works:

Every peak has one range or state, so a single row answers the question.

Try this

Anamudi, the highest peak of South India, is in which state?

Show solution

  1. Anamudi lies in the Anaimalai Hills.

  2. Those hills are in Kerala.

  3. Its height is 2,695 m.

Answer

Kerala

Type 3common3 practice Q

Himalayan ranges, hills and their features

How to spot it:

Order of the three ranges, 'Duns lie between', 'youngest or oldest mountains', or which hills belong to the Purvanchal.

Method

  1. Order north to south: Himadri, Himachal, Shiwalik.

  2. Duns lie between Himachal and Shiwalik.

  3. Purvanchal = Patkai Bum, Naga, Manipur and Mizo hills.

  4. Aravallis are the oldest fold mountains.

Why it works:

The three ranges form a fixed ladder of height, age and features.

Try this

Hill stations like Shimla, Mussoorie and Nainital lie in which Himalayan range?

Show solution

  1. Hill stations are in the widest range.

  2. That is the middle range.

Answer

The Himachal (Lesser or Middle) Himalaya

Type 4common3 practice Q

Lake superlatives and lake types

How to spot it:

'Largest freshwater, brackish or salt lake', 'floating national park lake', 'crater lake', or lake and state.

Method

  1. Read the adjective in the stem: fresh, brackish or salt.

  2. Match: Wular, Chilika, Sambhar.

  3. Special lakes: Loktak (phumdis), Lonar (crater), Pulicat (lagoon), Kolleru (freshwater).

Why it works:

The adjective is the whole clue, so read it before the options.

Try this

Loktak Lake, famous for floating vegetation called phumdis, is in which state?

Show solution

  1. Loktak has floating phumdis.

  2. The Keibul Lamjao National Park floats on it.

Answer

Manipur

Type 5common3 practice Q

Plateaus, ghats and coastal plains

How to spot it:

The Deccan Trap, Chota Nagpur, Malda gap, Western versus Eastern Ghats, or which coast (Konkan, Malabar, Coromandel) lies where.

Method

  1. West coast north to south: Konkan, Kanara, Malabar.

  2. East coast: Northern Circars in the north, Coromandel in the south.

  3. Western Ghats are continuous; Eastern Ghats are low and broken.

Why it works:

Coasts and Ghats follow a fixed north-south order.

Try this

Which statement is correct? 1. The Western Ghats are continuous. 2. The Eastern Ghats are higher than the Western Ghats.

Show solution

  1. Statement 1: the Western Ghats are continuous.

  2. Statement 2: the Western Ghats are higher, so it is false.

  3. The Eastern Ghats are cut by the Mahanadi, Godavari, Krishna and Kaveri.

Answer

Only 1

Type 6occasional

Hill ranges of the Purvanchal and the plateau edges

How to spot it:

'Which hills form the Purvanchal', 'Malda gap separates', 'Meghalaya Plateau consists of'.

Method

  1. Purvanchal = Patkai Bum, Naga, Manipur, Mizo.

  2. Meghalaya Plateau = Garo, Khasi, Jaintia hills.

  3. The Malda gap separates it from Chota Nagpur.

Why it works:

These are single-fact links that appear as odd-one-out items.

Try this

The Malda gap separates the Meghalaya Plateau from which plateau?

Show solution

  1. The gap lies between two plateaus.

  2. One is Meghalaya.

  3. The other is the mineral storehouse.

Answer

Chota Nagpur Plateau

Type 7common

Peak or pass by state: odd one out

How to spot it:

Four items (peaks or passes) and one belongs to a different state or range.

Method

  1. Place each item in its state or range.

  2. Find the one that stands alone.

  3. Check the extra fact (Sutlej at Shipki La, Atal Tunnel at Rohtang).

Why it works:

Odd-one-out questions test the state groups you have memorised.

Try this

Which of these passes is NOT in Ladakh? (a) Khardung La (b) Zoji La (c) Baralacha La (d) Karakoram Pass

Show solution

  1. Khardung La, Zoji La and Karakoram are Ladakh passes in the Z-K-K group.

  2. Baralacha La is on the Manali-Leh road.

  3. It is in Himachal Pradesh.

Answer

(c) Baralacha La

⚡ Highest-peak ladder

Claimed by India: K2. Administered by India: Kangchenjunga. South India: Anamudi. Nilgiris: Doddabetta. Aravallis: Guru Shikhar. Satpura: Dhupgarh.

⚡ Lake adjectives: Fresh Wular, Brackish Chilika, Salty Sambhar, Floating Loktak

Say it as one chain. Examiners swap the adjectives between the four lakes.

09

Mistakes to avoid

Where most students lose marks on this subtopic.

Mistake 01

Calling the Shiwaliks the oldest range.

The Shiwaliks are the youngest. The Aravallis are the oldest fold mountains.

Mistake 02

Placing the Duns between Himadri and Himachal.

Duns lie between Himachal and Shiwalik.

Mistake 03

Treating Nathu La as the traditional Kailash Mansarovar route.

The traditional route is Lipulekh (Uttarakhand). Nathu La is in Sikkim.

Mistake 04

Swapping lake adjectives, such as Chilika as freshwater.

Wular is fresh, Chilika is brackish, Sambhar is salt.

Mistake 05

Calling the Eastern Ghats continuous.

The Western Ghats are continuous. The Eastern Ghats are broken by rivers.
