Which is the largest part of the northern plains and is formed of older alluvium?

Key Points

• Bhangar is the largest part of the northern plains and is formed of older alluvium.
• The northern plains of India are divided into four regions: Bhabar, Terai, Bhangar, and Khadar.
• Bhangar represents the upland alluvial tract and is composed of older alluvium, known as Bangar.
• It lies above the floodplains of rivers and is characterized by a higher concentration of calcium carbonate nodules, known as 'Kankar'.
• This region is less fertile compared to the newer alluvium found in the Khadar region, but it is still significant for agriculture.

Additional Information

• Khadar refers to the newer, younger alluvium found in the floodplains of rivers, which is very fertile and replenished annually by river floods.
• Bhabar is the narrow belt lying along the foothills of the Shiwaliks, characterized by coarse alluvium and pebbles.
• Terai is the marshy tract lying next to the Bhabar region, known for its high water table and dense forests.
• The northern plains are crucial for India's agriculture, providing fertile land for the cultivation of various crops.
