Geographical Diversity of India — Himalayas & Plains
NCERT Class 7 — Exploring Society: India and Beyond | Chapter 1 — Geography
India — A Land of Many Landscapes
Opening Quote
To us, by its very geography, the country appears to be quite distinct from other countries, and that itself gives it a certain national character.
— Sri Aurobindo
India ranks as the seventh-largest country on Earth. Together with its neighbours — Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka, and Myanmar — it forms the Indian Subcontinent?. The word “sub” here means a smaller part of the continent of Asia. In 1984, when astronaut Rakesh Sharma was asked how India looked from space, he quoted a famous early-20th-century poem, calling it better than the whole world.
For the purpose of study, we can identify five major geographical regions of India:
The Great Mountain Zone
The Himalayan range stretching across six countries, with peaks over 8000 m.
Ganga & Indus Plains
Vast fertile plains nourished by rivers from the Himalayas, supporting dense populations.
The Desert Region
The Thar Desert — a vast arid zone in the northwest, a natural barrier with extreme temperatures.
The Southern Peninsula
The triangular Deccan Plateau flanked by the Western and Eastern Ghats.
The Islands
Lakshadweep in the Arabian Sea and Andaman & Nicobar in the Bay of Bengal.
The Himalayas? stand as a natural barrier in the north, while the Thar Desert? and Arabian Sea mark the western limits. To the south lies the Indian Ocean, and to the east, the Bay of Bengal. These features separate India from the rest of Asia and have profoundly shaped the country’s climate, culture, and history.
LET’S EXPLORE — Reading the Physical Map
L3 Apply
Open the physical map of India at the end of your textbook. Observe the different colours shown. Recall the types of landforms — mountains, plains, and plateaus.
- Which landforms can you identify using the legend?
- What do the different colours on the map represent?
- Can you approximately read the latitude and longitude where India lies?
Guidance
The map legend uses colours to show altitude (height above sea level). Darker greens indicate low-lying plains, browns show plateaus, and whites represent snow-covered mountains. India lies approximately between 8°N and 37°N latitude and 68°E to 97°E longitude.
The Himalayas — The Mighty Mountain Wall
The Himalayan range extends about 2500 km across six countries: India, Nepal, Bhutan, China, Pakistan, and Afghanistan. Many of its peaks soar above 8000 metres — these are collectively called the Eight Thousanders. The word Himalaya itself comes from two Sanskrit words: hima (snow) and alaya (abode), meaning the dwelling place of snow.
Remember
Eight Thousanders: Mountain peaks in the Himalayan range that exceed 8000 metres in height, including Mount Everest (the world’s tallest peak) and Kanchenjunga.
Why the Himalayas Matter
During summer, melting snow feeds major rivers such as the Ganga, Indus, and Brahmaputra. These rivers and their tributaries provide water for drinking, agriculture, and industry to hundreds of millions of people. For this reason, the Himalayas are sometimes called the “Water Tower of Asia”. Beyond their hydrological importance, the mountains hold deep cultural and spiritual significance — temples and monasteries built within them attract monks and spiritual seekers from around the world.
DON’T MISS OUT — Gaumukh
L2 Understand
The Bhagirathi River, a major tributary of the Ganga, originates from Gaumukh? (“Cow’s Mouth”) in Uttarakhand. It is the edge of the Gangotri Glacier — one of the largest glaciers in the Indian Himalayas. This glacier is considered sacred and attracts many pilgrims. Gaumukh is also a popular trekking destination.
How the Himalayas Were Formed
Millions of years ago, India was part of a larger landmass called Gondwana?, with Africa as its neighbour. At some point, it broke away and began drifting northward. About 50 million years ago, it collided with the Eurasian landmass. As the Indian plate pushed against Eurasia, the land between them crumpled and rose — much like a carpet wrinkles when you push it from one side. That is how the mighty Himalayas formed!
Remarkably, India continues to push into Asia at about five centimetres per year — much slower than the rate at which your hair grows. This means the Himalayas are still growing taller by roughly five millimetres annually. Over a thousand years, that adds up to five metres!
Three Ranges of the Himalayas
| Range | Also Called | Characteristics | Examples |
|---|---|---|---|
| Himadri | Greater Himalayas | Highest and most rugged; permanently snow-covered; very few human settlements | Mount Everest, Kanchenjunga |
| Himachal | Lower Himalayas | Moderate climate; rich biodiversity; popular hill stations | Nainital, Darjeeling, Shimla, Mussoorie |
| Shivalik Hills | Outer Himalayas | Lowest range; rolling hills and dense forests; transition zone to the plains | Rich wildlife habitats near the Gangetic Plains |
LET’S EXPLORE — States in the Himalayas
L3 Apply
Using both the physical and political maps in your textbook, locate the states that lie in the different parts of the Himalayas. Which states fall in the Greater Himalayas? Which are in the Lower Himalayas or the Shivalik Hills?
Guidance
Himalayan states include Jammu & Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Sikkim, and Arunachal Pradesh. Hill stations such as Shimla (Himachal Pradesh) and Nainital (Uttarakhand) lie in the Himachal range.
DON’T MISS OUT — Traditional Himalayan Houses
L2 Understand
In the western Himalayan region, people use a traditional building method called kath-kuni or dhajji-dewari. It combines locally available stone and wood. This construction keeps homes warm in winter and provides resistance against mild earthquakes — a clever adaptation to local conditions.
UNESCO Heritage
The Great Himalayan National Park in Himachal Pradesh has been declared a UNESCO World Heritage Site. It harbours an extraordinary diversity of plant and animal life. Both the government and local village communities work together to conserve its biodiversity.
The Cold Desert of India — Ladakh
The word “desert” usually makes us think of scorching heat. However, Ladakh? is a cold desert where winter temperatures can plunge below −30°C. The region receives very little rainfall and features a rugged landscape of rocky terrain, deep valleys, and lakes such as Pangong Tso (tso means lake).
The terrain here has been described as resembling the surface of the moon, earning it the nickname “Moonland”. Geologists explain that when the Indian plate collided with Eurasia, the folded rock was once part of an ancient ocean floor — hence it is largely made of sand and clay. Over millions of years, wind and rain have eroded these mountains into their distinctive shapes.
Despite the harsh conditions, Ladakh supports unique wildlife including snow leopards, ibex, and Tibetan antelopes. The Ladakhi people live a simple life, and the region is famous for its ancient monasteries and vibrant festivals such as Losar and the Hemis Festival. Yaks are central to life here — reared for milk, meat, wool, dung, and transport.
The Gangetic Plains — India’s Lifeline
Moving south from the Himalayas, we reach the vast and fertile Gangetic Plains?. These plains have been central to India’s history and civilisation for thousands of years. The Ganga, Indus, and Brahmaputra river systems, along with their extensive network of tributaries, enrich the soil with minerals, making the region extremely fertile and ideal for agriculture.
The flat landscape has enabled the development of an elaborate transportation network — roads and railways that move people and goods over long distances. These rivers have been used for travel and trade for millennia.
DON’T MISS OUT — The Son of Brahma
L2 Understand
Most rivers in India are named after goddesses — Ganga, Yamuna, Kaveri, and so on. The Brahmaputra, however, means “the son of Brahma”. Interestingly, this river grows larger during summer rather than drying up! Can you guess why? (Hint: Think about melting snow in the Himalayas.)
LET’S EXPLORE — Lights of the Plains
L4 Analyse
Look at a satellite image of India at night. Notice how the concentration of lighting is dense over the Gangetic Plains. What could explain this concentration?
Guidance
The fertile plains support a very dense population due to abundant water, flat land for agriculture, and well-developed transport networks. More people means more settlements, industries, and therefore more lighting visible from space.

Frequently Asked Questions — Himalayas Plains
What are the five major geographical regions of India?
India's five major geographical regions are: (1) The Himalayan Mountain Zone — stretching about 2500 km across six countries with peaks above 8000 metres; (2) The Ganga and Indus Plains — vast fertile lowlands nourished by Himalayan rivers; (3) The Desert Region — the Thar Desert in the northwest; (4) The Peninsular Plateau — the triangular Deccan Plateau flanked by the Western and Eastern Ghats; and (5) The Islands — Lakshadweep in the Arabian Sea and Andaman & Nicobar in the Bay of Bengal. These regions give India remarkable geographical diversity.
How were the Himalayas formed?
The Himalayas were formed when the Indian landmass, originally part of the ancient supercontinent Gondwana, broke away and drifted northward. About 50 million years ago, it collided with the Eurasian plate. The immense pressure caused the land between the two plates to crumple and rise — similar to how a carpet wrinkles when pushed from one side. India continues to push into Asia at about five centimetres per year, which means the Himalayas are still growing taller by roughly five millimetres each year.
What are the three ranges of the Himalayas?
The Himalayas consist of three parallel ranges: (1) Himadri or the Greater Himalayas — the highest range with permanently snow-covered peaks above 6000 metres, including Mount Everest and Kanchenjunga; (2) Himachal or the Lower Himalayas — the middle range with heights between 1000 and 4500 metres, known for hill stations like Shimla and Manali; (3) Shivalik or the Outer Himalayas — the southernmost and lowest range, with heights between 600 and 1200 metres, rich in forests and wildlife.
Why are the Himalayas called the Water Tower of Asia?
The Himalayas are called the Water Tower of Asia because during summer, melting snow from their glaciers feeds major rivers such as the Ganga, Indus, and Brahmaputra. These rivers and their tributaries provide water for drinking, agriculture, and industry to hundreds of millions of people across India, Pakistan, Bangladesh, Nepal, and other countries. The Gangotri Glacier alone is the source of the Bhagirathi River, a key tributary of the Ganga.
What is Ladakh and why is it called a cold desert?
Ladakh is a high-altitude region in northern India where winter temperatures can drop below minus 30 degrees Celsius. It is called a cold desert because it receives very little rainfall — the Himalayas block monsoon winds from reaching the area. Despite the harsh conditions, Ladakh is home to unique wildlife like snow leopards and the Tibetan wild ass. Its terrain resembles the surface of the moon, earning it the nickname Moonland. The region also has ancient Buddhist monasteries and the famous Pangong Tso lake.
What are the Gangetic Plains and why are they important?
The Gangetic Plains, also known as the Northern Plains, are vast fertile lowlands formed by the alluvial deposits of the Ganga, Indus, and Brahmaputra river systems. They stretch across northern India and are among the most densely populated areas in the world. These plains are critically important because their rich soil supports intensive agriculture, producing wheat, rice, sugarcane, and other crops that feed millions. The flat terrain has also enabled extensive road and rail networks for trade and connectivity.
What is Gondwana and how is it related to India?
Gondwana was an ancient supercontinent that existed millions of years ago, comprising present-day India, Africa, South America, Antarctica, and Australia joined together. India was originally part of Gondwana with Africa as its neighbour. At some point, India broke away and began drifting northward across what is now the Indian Ocean. About 50 million years ago, it collided with the Eurasian landmass, and the force of this collision created the Himalayan mountain range.
