Question

Choose the correct statements about Bhangar and Khadar:

1. Khadar is younger, found in floodplains and replenished annually.

2. Bhangar is older alluvium, less fertile and found away from floodplains.

• A. 1 only
• B. 2 only
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

Answer:

C. Both 1 and 2

• Correct Answer: Option C - Both 1 and 2

• Bhangar and Khadar are two different types of alluvial soils found in the Indo-Gangetic plains of India:

• Khadar (newer alluvium):

• These are younger alluvial soils deposited in the floodplains of rivers.

• They are replenished annually during floods when rivers deposit fresh silt.

• Khadar soils are more fertile due to their regular replenishment with minerals and organic matter.

• They are generally found closer to river banks and in active floodplains.

• They are lighter in color and more sandy in texture.

• Bhangar (older alluvium):

• These are older alluvial deposits found in the higher areas away from the floodplains.

• They are not replenished annually as they lie beyond the reach of flooding rivers.

• Bhangar soils are typically less fertile than Khadar as they have undergone leaching over time.

• They often contain calcareous deposits called 'kankar' (nodules of calcium carbonate).

• They are usually darker in color and have a higher clay content.
