Social Science (087) — AI-generated practice question

Bangar (Old Alluvial): It is older alluvial soil found on higher river terraces/doabs. It has a higher concentration of kanker (calcium carbonate nodules) and coarser particles, making it less fertile.

Khadar (New Alluvial): It is newer alluvial soil deposited by rivers in flood plains. It has finer particles and fewer kanker nodules.

More Fertile: Khadar is more fertile than Bangar because it has more fine particles, receives fresh deposits of silt regularly, and contains a greater proportion of nutrients suitable for crops like wheat, paddy, and sugarcane.

• Examiners expect a clear point-by-point distinction between Bangar and Khadar (at least 2 points of difference).
• The key reason Khadar is more fertile — finer particles + fewer kanker nodules — must be explicitly stated; just saying "newer" is insufficient for full marks.
• The textbook directly states: "It (Khadar) has more fine particles and is more fertile than the Bangar" — use this language.
• Mentioning a crop or two shows application and can earn you the third mark.
