Which Indian soil term is correctly associated with source or location “located above the active floodplain in many northern plains”, and also with “calcareous kankar nodules may occur within its profile”?

Correct Answer: Option B — Bangar. Bangar is correctly identified as located above the active floodplain in many northern plains. Bangar is also associated with calcareous kankar nodules may occur within its profile. Another identifying fact about Bangar is that calcareous kankar nodules may occur within its profile. A further exam-relevant fact about Bangar is that it is generally less frequently renewed by floods than khadar. Why the other options are incorrect: • Option A — Alluvial Soil: Alluvial Soil is widespread across the Indo-Gangetic-Brahmaputra plains and coastal deltas. It is incorrect here because Alluvial Soil is instead associated with it commonly contains varying proportions of sand, silt and clay. • Option C — Black Soil: Black Soil is extensive over the Deccan Trap region of Maharashtra, Madhya Pradesh and Gujarat. It is incorrect here because Black Soil is instead associated with it develops deep cracks during the dry season. • Option D — Red and Yellow Soil: Red and Yellow Soil is widespread over parts of the eastern and southern Peninsular plateau. It is incorrect here because Red and Yellow Soil is instead associated with it forms largely from weathering of ancient crystalline rocks. Exam Takeaway: Connect Bangar with “located above the active floodplain in many northern plains” and “calcareous kankar nodules may occur within its profile” for revision.
