Chapter 3 – Landforms and Life
Complete Notes | In-text Questions | Easy Explanations | Real Pictures | Revision
1. Introduction
The surface of the Earth is not the same everywhere. Some places are very high, some are flat, and some have raised flat surfaces. These different physical features of the Earth’s surface are called landforms.
Landforms develop over very long periods of time. They influence climate, water availability, plants, animals, occupations, transport, settlements, food habits and even the culture of people.
The chapter mainly studies three major types of landforms:
Mountains
Landforms that rise prominently above the surrounding land and usually have steep slopes.
Plateaus
Raised areas of land with a broad, more or less flat top.
Plains
Large areas of land that are flat or gently undulating.
2. The Big Questions
The three major types of landforms are mountains, plateaus and plains.
Mountains influence climate, provide water through snow and springs, support forests and wildlife, and attract tourists and pilgrims. People adapt to mountain conditions through activities such as terrace farming, herding and tourism.
Plateaus are important because many contain valuable minerals. Mining is an important activity in several plateau regions. Plateaus also support forests, farming, grazing and settlements adapted to their terrain.
Plains are generally suitable for agriculture because many river plains have fertile soil. Their flatter surface makes transport, construction, settlements and economic activities easier.
| Landform | Opportunities | Challenges |
|---|---|---|
| Mountains | Tourism, pilgrimage, terrace farming, herding, forests, freshwater and adventure activities. | Steep slopes, cold climate, landslides, avalanches, flash floods, difficult transport and limited farming land. |
| Plateaus | Mineral resources, mining, grazing, forests, waterfalls and some forms of farming. | Rocky terrain, soil erosion in some areas, difficult transport and challenges in large-scale farming. |
| Plains | Fertile soils, agriculture, easy transport, dense settlements, industries and trade. | Population pressure, pollution, groundwater depletion and flood risk in some areas. |
3. Mountains
Mountains are landforms that rise much higher than the surrounding landscape. They usually have a broad base, steep slopes and a narrower upper part. Several connected mountains form a mountain range.
Altitude
As altitude increases, temperature generally decreases. This is why higher mountain areas can remain covered with snow while lower areas may have forests, grasslands or settlements.
Snow and Mountain Rivers
At lower mountain altitudes, snow may melt during warmer months. Meltwater can feed streams and rivers. At very high altitudes, some snow remains for long periods.
4. Young and Old Mountains
Mountains can differ in appearance depending on their age and the effects of erosion.
| Young Mountains | Older Mountains |
|---|---|
| Usually taller and more rugged. | Usually more rounded because erosion has acted on them for a very long time. |
| Often have sharper peaks. | Often have smoother or lower-looking slopes. |
| The Himalayas are an example of young fold mountains. | The Aravalli range is a much older mountain system. |
5. Life in the Mountains
Life in mountain regions requires people to adapt to steep slopes, low temperatures, changing weather and limited flat land.
Terrace Farming
On steep slopes, farmers may cut the slope into a series of step-like fields. This is called terrace farming.
Terraces reduce the speed of flowing water and make cultivation possible on slopes.
Herding
In many mountain regions, keeping animals is important. Herding can be more practical than large-scale crop farming where flat agricultural land is limited.
Tourism
Beautiful scenery, clean mountain air, snow, forests and adventure activities attract tourists.
Activities may include:
Trekking Skiing Mountaineering Paragliding Nature Tourism Pilgrimage6. Challenges in Mountain Regions
Mountain environments can be beautiful and resource-rich, but people may also face serious challenges.
| Challenge | Simple Explanation |
|---|---|
| Flash Flood | A sudden local flood that can occur after very heavy rainfall or a cloudburst. |
| Landslide | The sudden movement or collapse of soil, rocks or other material down a slope. |
| Avalanche | A rapid movement of snow and ice down a mountain slope. |
| Heavy Snowfall | Can block roads and make travel and daily activities difficult. |
| Cold Weather | Very low temperatures can make farming, travel and construction difficult. |
| Excessive Tourism | Too many visitors can put pressure on fragile mountain ecosystems. |
7. LET’S EXPLORE – Page 42
Sample answer: The landscape around a school may include buildings, roads, open land, farms, trees, hills or rivers depending on the location. The landscape can change within a few kilometres because physical features and human activities are not the same everywhere.
This is an observation-based activity, so students should also write what they actually see around their school.
A journey through India may show different landscapes such as plains, plateaus, hills, mountains, river valleys and coastal areas. The exact answer will depend on the route followed by the student.
8. THINK ABOUT IT – Page 43
9. Mountains and Indian Culture
Mountains have an important place in Indian culture. Many mountain peaks, rivers, lakes and forests have religious or cultural significance.
People have travelled to mountain regions for pilgrimage for centuries. Mountain landscapes also appear in Indian literature, poetry and traditions.
10. LET’S EXPLORE – Page 46
The western ocean refers to the Arabian Sea, which lies to the west of India.
The eastern ocean refers to the Bay of Bengal, which lies to the east of India.
The expression ‘Lord of mountains’ refers to the Himalayas, the great mountain system in the north of India.
The Ganga is mentioned because it is closely connected with the Himalayas, the plains and Indian life.
- Its river system supports a large population.
- Its waters are important for agriculture and daily life.
- It has great cultural and religious importance.
- The Ganga plain is one of India’s important fertile plains.
- The river connects mountain regions with the plains.
11. Plateaus
A plateau is a raised area of land with a broad and generally flat or gently undulating top. It is often higher than the surrounding land. Some sides may have steep slopes.
Why are plateaus important?
- Many plateaus contain valuable mineral resources.
- Mining is an important activity in several plateau regions.
- Some plateau areas contain forests and wildlife.
- Some support farming and animal grazing.
- Plateaus can contain beautiful waterfalls and scenic landscapes.
12. Important Plateaus
| Plateau | Important Feature |
|---|---|
| Tibetan Plateau | One of the highest and largest plateau regions of the world. |
| Chhota Nagpur Plateau | Important mineral-rich plateau region of India. |
| East African Plateau | Large elevated region with diverse landscapes and resources. |
| Patagonian Plateau | Large plateau region in southern South America. |
13. LET’S EXPLORE – Page 53
Use the map’s colour key to identify each feature.
- Tibetan Plateau – Plateau
- Rocky Range – Mountain range
- Nile Plain – River plain
Other examples shown in the map include the Himalaya and Andes mountain ranges, Tibetan and East African plateaus, and Ganga-Brahmaputra, Nile and Amazon plains.
14. Plains
Plains are broad areas of land that are flat or gently undulating. They usually do not have large hills and are generally easier to travel across than mountainous areas.
Why are plains important?
- They often have fertile soils.
- They are suitable for agriculture.
- Building roads and settlements is comparatively easier.
- Transport and trade can develop easily.
- Large populations can live in plains.
15. River Plains and Sediments
Many plains are formed or enriched by rivers.
Rivers flowing from mountains carry tiny particles of rock, sand and soil. These materials are called sediments.
When rivers slow down after reaching flatter areas, they may deposit these sediments. Over time, such deposits can create fertile plains.
16. Ganga Plain
The Ganga plain is one of India’s important river plains. It has supported large populations and extensive agriculture.
Crops grown in the wider Gangetic region include rice, wheat, maize, barley, millets and several fibre crops.
Rivers also support fishing, transport, cultural activities and settlements.
17. LET’S EXPLORE – Page 54
(a) Which colour is the Ganga plain?
(b) What does the white expanse represent?
(c) What does the brown expanse at the bottom left of the image represent?
(a) The Ganga plain appears mainly as the green-coloured vegetated region in the satellite image.
(b) The white expanse represents snow-covered high mountain areas of the Himalayas.
(c) The brown area represents the drier and less-vegetated land towards the south-western side of the image.
The important point is to observe how the colours help us recognise different physical and environmental regions.
18. Life in the Plains
Plains have supported human settlements for thousands of years. Their fertile soils, water availability and relatively easy transport make them favourable for agriculture and settlement.
Major activities in plains
- Agriculture
- Fishing
- Trade
- Transport
- Industry
- Settlement
- Cultural activities
However, plains can also face challenges such as high population density, pollution, floods in some areas and excessive groundwater use.
19. Rivers and Culture
Rivers are not only sources of water. They can also have deep cultural importance.
Many communities consider particular river sources and confluences sacred. Such places may become centres of festivals, ceremonies and pilgrimages.
20. LET’S EXPLORE – Page 55
Examples include:
- Gangotri – associated with the source of the Ganga.
- Yamunotri – associated with the source of the Yamuna.
- Devprayag – associated with the confluence of the Alaknanda and Bhagirathi.
- Prayagraj – famous for the Triveni Sangam.
Students can also give an example from their own region.
This is an observation activity. Possible observations include:
- Fishing
- Boating
- Agriculture near the river
- Washing or other household activities
- Religious ceremonies
- Festivals and pilgrimages
- Tourism
Students should write what they actually observe at a nearby river.
21. River Transport
Plains generally have gentle slopes. This can make river navigation easier in suitable stretches.
In some areas, boats are still used to move people and goods. Rivers have therefore supported transport and economic activities for a very long time.
22. LET’S EXPLORE – Page 56
| Tourist Destination | Landform |
|---|---|
| Shimla | Mountain / hill region |
| Mussoorie | Mountain / hill region |
| Leh | High-altitude mountain and cold desert region |
| Varanasi | River plain |
| Jaisalmer | Desert region |
| Goa | Coastal region |
23. A Look at the Desert
Although the chapter focuses mainly on mountains, plateaus and plains, deserts provide another useful example of how landforms and environments shape human life.
The Thar is a hot desert region with very limited rainfall. People living there have developed ways of adapting to scarce water and high temperatures.
Desert regions have their own plants, animals, occupations, settlements, food traditions and cultures.
24. Landforms and Human Life
| Aspect | Mountains | Plateaus | Plains |
|---|---|---|---|
| Surface | High and steep | Raised and relatively flat | Flat or gently undulating |
| Farming | Often terrace farming | Depends on soil and terrain | Generally easier and widespread |
| Mining | Some areas | Very important in mineral-rich areas | Less characteristic than plateaus |
| Transport | Often difficult | Can be difficult in rugged areas | Generally easier |
| Population | Usually lower in very high areas | Varies | Often high |
| Tourism | Very important | Important in scenic areas | Also important in cities and cultural centres |
25. Landforms and Culture
The environment in which people live influences their way of life. Landforms can affect:
- Food habits
- Clothing
- Housing
- Occupations
- Transport
- Festivals
- Religious practices
- Stories and literature
- Settlement patterns
26. Resilience
People living in different landforms develop different forms of resilience. For example, mountain communities adapt to steep slopes and cold weather, while desert communities adapt to limited water.
27. BEFORE WE MOVE ON
- Landforms are broadly classified into three major types: mountains, plateaus and plains.
- Each landform has its own physical characteristics and environment.
- Landforms influence people’s occupations, settlements, transport and culture.
- Mountains provide freshwater, forests, tourism and many other resources, but also present challenges such as landslides and avalanches.
- Plateaus are often rich in minerals and support mining and other activities.
- Plains are generally suitable for agriculture, settlements and transport.
- Rivers help form fertile plains and support economic and cultural activities.
- People adapt to the landforms in which they live.
28. QUESTIONS, ACTIVITIES AND PROJECTS – Page 58
Sample answer: My town/city is located in a plain region. The area has mostly level land, roads, houses, fields and nearby water bodies. The flat land makes transport and construction comparatively easy.
Students should modify this answer according to their actual location.
The journey takes us through three major landforms:
- Chhota Nagpur: A plateau region with raised land and important mineral resources.
- Prayagraj: Located in the broad plains associated with the Ganga river system.
- Almora: Located in the Himalayan mountain region, with hills, valleys and steep slopes.
