The Northern Plains Class 4 Notes SST

What is a Plain?

A flat and level land is called a plain.

The plains of India include

• The Northern Plains and,
• The Coastal Plains

What are Northern Plains?

The Northern Plains are an important physical division of India. It is also known as Indo - Gangetic plains. 

Location of the Northern Plains

• The Northern Plain is one of the largest and most fertile plains of India. It is one of the World’s most intensively farmed areas.
• They are located between the Himalayan rivers in the north and the Peninsular Plateau in the south.

How are The Northern Plains Formed?

The Northern Plains are made up of two river basins. 

• The basin in the west is watered by Indus and its tributaries. The eastern basin is watered by the river Ganga and its tributaries, and the Brahmaputra.

Rivers of Northern Plain

• The plain is the result of the deposit of soil carried by the rivers Indus, Ganga, Brahmaputra, and their tributaries.

A smaller river that flows into a bigger river is the tributary of the bigger river.

Importance of Northern Plains

The Northern Plains region is one of the most fertile regions of our country.

• This region supplies food grains to many of the central and southern states. 
• The fertility of the soil in the basins differs due to many factors. 

In Northern Plains, most farmers use tractors to plow their fields.

• Some of the factors are the distance from the rivers, rainfall during monsoons, and the height from the sea. 
• Generally, the Great Northern Plains are fertile, densely populated, and are the basins of Sutlej, Beas, Ravi, Ganga, Yamuna, Brahmaputra, and their tributaries. Indus, Ganga, Yamuna and Brahmaputra originate in the Himalayas.
• Some of the well-known ancient cities are situated on the bank of these rivers especially on the bank of the river Ganga.
  
  

• Rishikesh, Haridwar, Prayag, Allahabad, Varanasi, Pataliputra, and Kolkata are some prominent out of them.

Parts of the Great Northern Plains+

It is interesting to note that the Great Northern Plain can be broadly studied in four parts.
These are
Location of Northern Plains on Indian Map

1. Western Plain
2. North Central Plain
3. Eastern Plain
4. Brahmputra Plain

Western Plain: Rajasthan

1. The Western Plain encompasses regions like Rajasthan and parts of Punjab.
2. Historically, it was watered by ancient rivers such as Saraswati and Drishadvati, although these rivers are now mostly invisible or dried up. 
3. Despite the arid climate in some areas, fertile regions like Bikaner are found within this plain. 
4. Bikaner is known for its agriculture, particularly for crops like wheat, mustard, and cotton.

5. The soil here is rich in nutrients, making it suitable for cultivation. 

North Central Plain: Punjab, Haryana & UP

1. The North Central Plain includes states like Punjab, Haryana, and parts of Uttar Pradesh. 
2. This region owes its fertility to the presence of rivers like the Sutlej, Beas, Ravi, Ganga, and Yamuna, which originate from the Himalayas.

3. Agriculture is the primary occupation in this plain, with crops such as rice, wheat, sugarcane, and cotton being cultivated extensively.

4. The population density in this area is high due to the availability of fertile land and water resources.

Eastern Plain: Bihar & West Bengal

1. The Eastern Plain covers parts of Uttar Pradesh, Bihar, and West Bengal. It owes its fertility to the Ganga and its tributaries, which bring nutrient-rich sediment from the Himalayas. 
2. This region is an agricultural hub, producing crops like rice, jute, sugarcane, and pulses.

3. However, the Eastern Plain faces frequent floods, especially in West Bengal, where heavy rainfall is common. 
4. These floods replenish the soil with nutrients but also cause damage to crops and infrastructure.

Brahmaputra Plain: Bangladesh

1. The Brahmaputra Plain is primarily located in Bangladesh, although it extends into parts of northeastern India. 
2. It is formed by sediment deposited by the Brahmaputra river and its tributaries, making it exceptionally fertile. 
3. Agriculture is the mainstay of the economy in this region, with crops like rice, tea, jute, and mustard being cultivated.

4. However, the Brahmaputra Plain is prone to frequent floods, which can cause devastation to crops, homes, and infrastructure. 
5. These floods also contribute to the dynamic nature of the landscape, with river channels constantly shifting and forming new islands. 
6. Despite the challenges posed by floods, the Brahmaputra Plain remains vital for agriculture and supports a dense population. 

Ganga Brahmaputra Delta

• By the time a river reaches its end, it has lots of sediment. This sediment settles down and makes the river split into many channels or distributaries. 
• In between these distributaries, triangular-shaped islands are formed. 
• These are called Delta because they resemble a triangle(Δ). 
• The Ganga- Brahmaputra delta is called as Sunderban.

Characteristics of Northern Plains

1. Fertility: The fertility of the northern plains is unparalleled due to the continuous deposition of nutrient-rich soil by the rivers, making it ideal for agriculture.
2. Population Density: These plains are densely populated regions, particularly the North Central and Eastern Plains, owing to the abundance of fertile land and water resources.
3. River Origins: The major rivers of the northern plains, including the Indus, Ganga, Yamuna, and Brahmaputra, originate from the Himalayan mountain ranges, ensuring a steady supply of water and sediment.

4. Ancient Cities: Several historically significant cities, such as Rishikesh, Haridwar, Varanasi, and Kolkata, are located along the banks of these rivers, showcasing the cultural and historical importance of the region.

Formation of Deltas

1. Deposition Process: As rivers approach their mouths or deltas, they deposit sediment carried from upstream areas.
2. Delta Formation: The deposited sediment leads to the formation of distributaries and triangular-shaped islands.
   
   Sunderban Delta
   
   
3. Sunderban Delta: The delta formed by the confluence of the Ganga and Brahmaputra rivers is known as the Sunderban delta, characterized by its rich biodiversity and mangrove forests.
