Which Indian soil term is correctly associated with source or location “found across Himalayan and other highland regions”, and also with “texture and humus content change markedly with altitude and slope”?

Correct Answer: Option B — Forest and Mountain Soil. Forest and Mountain Soil is correctly identified as found across Himalayan and other highland regions. Forest and Mountain Soil is also associated with texture and humus content change markedly with altitude and slope. Another identifying fact about Forest and Mountain Soil is that texture and humus content change markedly with altitude and slope. A further exam-relevant fact about Forest and Mountain Soil is that terraced and valley areas may support tea, spices and temperate fruits. Why the other options are incorrect: • Option A — Saline and Alkaline Soil: Saline and Alkaline Soil is occurs in arid tracts, poorly drained plains and some coastal areas. It is incorrect here because Saline and Alkaline Soil is instead associated with reh, usar and kallar are regional names associated with salt-affected land. • Option C — Peaty and Marshy Soil: Peaty and Marshy Soil is found in parts of Kerala, coastal wetlands and other poorly drained depressions. It is incorrect here because Peaty and Marshy Soil is instead associated with it commonly has high humus and may be acidic. • Option D — Khadar: Khadar is deposited repeatedly along low-lying river floodplains. It is incorrect here because Khadar is instead associated with fresh silt renewal generally makes it highly fertile. Exam Takeaway: Connect Forest and Mountain Soil with “found across Himalayan and other highland regions” and “texture and humus content change markedly with altitude and slope” for revision.
