Where India lies and its five regions
Look at the wall map of India in your classroom: mountains on top and sea on three sides. To know a village you first learn its boundary, then its lanes; a country is understood the same way.
India is the seventh-largest country in the world and a part of Asia. Together with Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and Myanmar it forms the Indian Subcontinent. For study we speak of five regions: the great mountain zone, the plains of the Ganga and Indus, the desert, the southern peninsula and the islands.
Key points
- Himalaya in the north, Thar Desert and Arabian Sea in the west, Indian Ocean in the south, Bay of Bengal in the east: these are India's natural boundaries.
- These boundaries set India somewhat apart from the rest of Asia and played a big part in shaping its climate, culture and history.
- The different colours on a physical map show the height of the land; always read the map's legend first.
- India is part of the continent of Asia, so this large region is called a 'subcontinent', not a separate continent.
Where India lies and its five regions
In the app you can move this figure with your finger.
Open in the app- Easy : Which bay lies to the east of India? → The Bay of Bengal.
- Medium : Why 'subcontinent'? → It is a part of Asia and, with its neighbours, forms one distinct region.
- Exam-type : Name the five regions of India. → Mountain zone (Himalaya), plains, desert, peninsular plateau, islands; add one feature of each for full marks.
India is the seventh-largest country by area.
Thinking a 'subcontinent' is a separate continent is wrong; it is a part of Asia.
Five regions in order: Mountain, Plain, Desert, Plateau, Islands. Memory clue : Mountain-Plain-Desert-Plateau-Island = M-P-D-P-I: 'My Pet Dog Plays Inside'.

The Himalayas: abode of snow
The river water we drink, and the rice or wheat grown with it, began its journey in high snowy mountains.
Himalaya comes from 'hima' (snow) and 'ālaya' (home): the home of snow. This wall of mountains, about 2500 km long, passes through six countries: India, Nepal, Bhutan, China, Pakistan and Afghanistan.
The Himalayas: abode of snow
In the app you can move this figure with your finger.
Open in the appKey points
- Formation: India was once part of a huge landmass called Gondwana. It broke away, drifted north and hit Eurasia about 50 million years ago. The land between crumpled and rose like a pushed carpet, forming the Himalayas. India still moves about 5 cm a year, so the Himalayas rise about 5 mm a year.
- Three ranges: Himadri (highest, snow all year, Everest and Kanchenjunga, few settlements), Himachal (middle, mild climate, hill stations like Shimla, Darjeeling, Nainital, Mussoorie), Shivalik (outermost and lowest, rolling hills and dense forest, a step down to the plains).
- Water tower of Asia: summer snowmelt feeds the Ganga, Indus and Brahmaputra. The Bhagirathi begins at Gaumukh in Uttarakhand, at the edge of the Gangotri Glacier.
- Ladakh is a cold desert: winter temperatures fall below -30 °C, rain is very little, and the land looks moon-like (hence 'moonland'). Pangong Tso is a salty lake. The yak gives milk and wool and carries loads.
- Easy : How far does India move north each year? → About 5 cm.
- Medium : How much will the Himalayas rise in 1000 years? → 5 mm × 1000 = 5000 mm = 5 m.
- Exam-type : Compare Himadri and Shivalik. → Himadri: highest, snow all year, few settlements. Shivalik: lowest, hills and forests, next to the plains.
Peaks above 8000 m are called the 'Eight Thousanders'.
Believing every desert is hot is wrong; Ladakh is a cold desert.
Height falls from north to south: Himadri → Himachal → Shivalik. Memory clue : H-H-S = Highest, Hill stations, Shortest.

| Point | Himadri | Himachal | Shivalik |
|---|---|---|---|
| Position | Northernmost | Middle | Outermost (southern) |
| Height and climate | Highest, snow all year | Middle height, mild climate | Lowest |

The Gangetic Plains: fertile land
From a train window in north India you see flat fields stretching far away. Flat land makes roads, railways and cities easy to build.
South of the Himalayas lie the vast, fertile Gangetic Plains, nourished by the Ganga, Indus and Brahmaputra river systems. The rivers carry minerals and enrich the soil.
Key points
- Farming: fertile soil and water give rich crops, and many crops can be grown on the same land in a year (multi-cropping). A large share of India's people live here.
- Transport: flat land allowed a dense network of roads and railways. For thousands of years the Ganga, Brahmaputra and other rivers carried travellers and trade.
- Power: rivers also give hydroelectricity. The Brahmaputra grows bigger in summer instead of drying up, because snow melting in the Himalayas feeds it. Delhi lies on the banks of the Yamuna.
- Wildlife: the tiger (revived with Project Tiger), the Indian gharial (near extinction), the grey langur, and the peacock, our national bird.
- Easy : Why is the soil of the plains fertile? → Rivers bring minerals.
- Medium : Why is the population large here? → Flat land + fertile soil + water suit farming, so settlements grew.
- Exam-type : How do the Himalayas help farmers in the plains? → Snow melts → rivers flow → water and minerals reach the plains → crops grow.
The Ganga, Indus and Brahmaputra river systems all come from the Himalayas.
Do not think Himalayan rivers dry up in summer; melting snow actually makes them bigger.
Flat + fertile + water = many people. Memory clue : Think 'F-F-W': Flat, Fertile, Water.

| Point | Himalaya | Gangetic Plains |
|---|---|---|
| Land | High, rugged | Flat, vast |
| Settlement | Few (especially in Himadri) | Very many |

The Thar Desert and the Aravalli Hills
When you scrub dishes with the tap running, remember the people of the Thar: they scour utensils with sand, rinse with a little water, and then water a plant with it.
The Thar Desert (Great Indian Desert) lies in the west of India, mostly in Rajasthan, Gujarat, Punjab and Haryana. Wind shapes the sand into dunes that can reach 150 m. The Aravalli range is among the oldest mountains in the world, about 2.5 billion years old.
Key points
- Dunes do not keep one shape: when the wind shifts, sand moves into a new form. Very hot days, cold nights and lack of water make the desert a natural barrier.
- Life: water is scarce, so women often walk far to fetch it. In Rajasthan taanka or kund tanks store rainwater. Food, clothing and lifestyle suit the harsh conditions.
- Aravalli: highest peak Mount Abu (over 1700 m), but most hills are 300 to 900 m. It runs through Delhi, Haryana, Rajasthan and Gujarat. A drive of about four and a half hours from Mount Abu to Jodhpur shows a completely different landscape.
- Uses: minerals such as marble, granite, zinc and copper; forts like Chittorgarh, Kumbhalgarh and Ranthambore. Most important job: the Aravallis stop the Thar Desert from spreading further east.
- Easy : Which is the highest peak of the Aravalli? → Mount Abu.
- Medium : Why do dunes change shape? → When the wind shifts, the sand moves.
- Exam-type : Write the importance of the Aravalli. → Stops the Thar spreading east; minerals; historic forts.
The Aravalli is about 2.5 billion years old, far older than the Himalayas.
Dunes are not fixed like rock mountains; the wind keeps reshaping them.
Aravalli = the wall that holds back the Thar. Memory clue : Aravalli, 'A' for 'Arrests' the desert.
Spot the difference
| Point | Thar Desert | Aravalli |
|---|---|---|
| Type | Sandy and dry | Very ancient mountains |
| Feature | Dunes, water scarcity | Mount Abu, minerals, forts |
| Role | Natural barrier | Stops the desert spreading east |

The Peninsular Plateau
In the monsoon people visit waterfalls in the Ghats, and the same water can make electricity. This happens because rivers tumble down over the plateau.
A plateau is land that rises above its surroundings and has a more or less flat top; some sides are steep. A peninsula is land surrounded by water on three sides. The old triangular plateau of central and southern India, with sea on three sides, is called the Peninsular Plateau.
Key points
- Borders: Western Ghats on the west (taller, wall-like, close to the coast; the northern part is the Sahyadri), Eastern Ghats on the east (lower, broken hills). The vast highland between them is the Deccan Plateau.
- Rivers: the plateau tilts a little to the east, so the Godavari, Krishna, Kaveri and Mahanadi flow east to the Bay of Bengal. The Narmada and Tapti flow west to the Arabian Sea.
- Wealth: minerals, forests, fertile land, waterfalls and hydroelectricity. Coal is a fossil fuel, useful for electricity but a contributor to global warming.
- People and wildlife: tribal communities such as the Santhal, Gond, Baiga, Bhil and Korku live in dense forests; the Western Ghats shelter the lion-tailed macaque and king cobra and are a UNESCO World Heritage Site.
- Easy : Which Ghats are taller? → The Western Ghats.
- Medium : Why does the Godavari flow east? → The plateau tilts east.
- Exam-type : Why 'Peninsular Plateau'? → It is a plateau with the Arabian Sea, Bay of Bengal and Indian Ocean on three sides.
Godavari, Krishna, Kaveri, Mahanadi: east-flowing. Narmada, Tapti: west-flowing.
Not all plateau rivers flow east; the Narmada and Tapti flow west.
The two odd ones out: Narmada and Tapti. Memory clue : 'NT go West': Narmada and Tapti go west, others go east.

| Point | Western Ghats | Eastern Ghats |
|---|---|---|
| Height | Taller, wall-like | Lower |
| Form | Continuous, steep slopes | Broken into small hills |

Coasts, islands, the Sundarbans and the hills of the Northeast
Ports like Mumbai and fishing along the coast are all possible because India has a coastline of over 7500 km.
India's coastline is over 7500 km long. A triangular or fan-shaped landform built where a river drops sediment into a larger water body is a delta. A group of islands is an archipelago.
Key points
- West coast (Gujarat to Kerala, through Maharashtra, Goa, Karnataka): short, swift rivers from the Western Ghats form estuaries; the Narmada and Tapti estuaries are the largest. The Ghats lie close to the sea and there are many important ports.
- East coast (Ganga delta to Kanyakumari): wide plains and fertile deltas of the Mahanadi, Godavari, Krishna and Kaveri; Chilika and Pulicat lakes.
- Islands: Lakshadweep (Arabian Sea, 36 coral islands) and Andaman and Nicobar (Bay of Bengal, over 500 volcanic islands). Barren Island is India's only active volcano. Many freedom fighters were jailed in the Cellular Jail in the Andamans.
- Sundarbans and Northeast: the Sundarbans in the Ganga-Brahmaputra delta (half in India, half in Bangladesh) are known for mangroves and the Royal Bengal Tiger. The Garo, Khasi and Jaintia hills of the Meghalaya Plateau get some of the heaviest rain in the world; Mawlynnong is known for cleanliness and living root bridges.
- Easy : How long is India's coastline? → Over 7500 km.
- Medium : Why few deltas on the west coast? → Rivers are short and swift and form estuaries.
- Exam-type : Write the importance of Andaman and Nicobar. → Strategic location (watching the ocean), biodiversity, history of the Cellular Jail.
Lakshadweep is coral; Andaman and Nicobar are volcanic.
Deltas are not found on both coasts equally; the big ones are on the east.
West = estuary, East = delta. Memory clue : A delta spreads like a fan: fan in the East, estuary in the West.
Spot the difference
| Point | West coast | East coast |
|---|---|---|
| Rivers | Start in the Western Ghats, short and swift | Flow east from the plateau |
