3. Life in the Mountains
People:
- People live in SMALL villages on mountain slopes.

4. The Northern Plains
The NORTHERN PLAINS lie SOUTH of the Himalayas. They are formed by the rivers flowing down from the mountains.
'These plains are also called the INDUS-GANGA-BRAHMAPUTRA PLAINS. They are the most FERTILE region of India!'
Key Facts:
| Fact | Detail |
|---|---|
| Length | About 2,400 km |
| Width | 240 to 320 km |
| Soil | ALLUVIAL soil (very fertile — brought by rivers) |
| Population | The most DENSELY populated region of India |
| States covered | Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal, Assam |
Divisions of the Northern Plains:
| Section | Region | Key Features |
|---|---|---|
| Punjab Plains | Western part | Five rivers (Sutlej, Beas, Ravi, Chenab, Jhelum) |
| Ganga Plains | Central part | Largest section — very fertile |
| Brahmaputra Plains | Eastern part | In Assam — floods every year |
5. The Great Rivers
River Ganga:
- Origin: Gangotri Glacier (Uttarakhand).
- Length: 2,525 km.
- Flows through: Uttarakhand, Uttar Pradesh, Bihar, West Bengal → Bay of Bengal.
- 'The Ganga is the HOLIEST river for Hindus. Millions bathe in it for purification.'
River Yamuna:
- Origin: Yamunotri Glacier (Uttarakhand).
- Merges with Ganga at: Prayagraj (Allahabad).
- 'The Taj Mahal is on the banks of the Yamuna.'
River Brahmaputra:
- Origin: Tibet (as the Tsangpo River).
- Enters India in: Arunachal Pradesh.
- Flows through: Assam → Bangladesh → Bay of Bengal.
- 'The Brahmaputra is called the "SON OF BRAHMA" — it is one of the few rivers with a MALE name.'
Importance of Rivers:
- Provide WATER for drinking and irrigation.
- Used for TRANSPORTATION (boats).
- Provide FERTILE soil (alluvium).
- Generate HYDROELECTRICITY.
- Have RELIGIOUS significance.
6. Life in the Plains
People:
- Very HIGH population density — millions of people live here.
- Villages and CITIES are found everywhere.
- Major cities: Delhi, Kanpur, Lucknow, Patna, Kolkata, Guwahati.
Agriculture:
- The plains are the FOOD BASKET of India.
- Major crops: Rice, wheat, sugarcane, cotton, jute.
- Farming: Mostly INTENSIVE farming (small land, lots of labour).
Occupations:
| Occupation | Details |
|---|---|
| Farming | Most common — rice, wheat, sugarcane |
| Industry | Textiles, sugar mills, jute mills |
| Fishing | Common in rivers and ponds |
| Trade | Big cities have huge markets |
7. Common Mistakes
- Thinking all mountains are the same height: 'The Himalayas have THREE ranges. The Himadri (Greater Himalayas) is the HIGHEST. The Shivalik is the LOWEST.'
- Confusing which rivers are in which region: 'Ganga flows through NORTH India, NOT South India. Godavari and Krishna are the major rivers of South India.'
- Believing the plains are flat and boring: 'The plains are VERY important — they grow most of India's food. They are how India FEEDS itself!'
- Calling the Brahmaputra a female river: 'The Brahmaputra has a MALE name. Most Indian rivers have female names (Ganga, Yamuna, Godavari).'
8. Key Facts to Remember
- 'The Himalayas are the YOUNGEST and HIGHEST mountains in the world.'
- 'The Himalayas have THREE ranges: Himadri, Himachal, and Shivalik.'
- 'The Northern Plains are FERTILE because of the ALLUVIAL soil from rivers.'
- 'The three great rivers are Ganga, Yamuna, and Brahmaputra.'
- 'The Northern Plains are the FOOD BASKET of India.'
