Social Science (087) — AI-generated practice question

AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

Q1. [3] deep thorough-understanding
The Kudremukh iron ore deposit in Karnataka functions as a 100 per cent export unit. Analyse the factors — including transport technology and market linkages — that determine whether a mineral deposit becomes economically viable, using Kudremukh as your example.

Model Answer

A mineral deposit becomes economically viable when three key factors align:

  1. Grade/Quality of ore: Kudremukh deposits are among the largest in the world, justifying extraction costs.
  1. Transport technology: The ore is transported as slurry through a pipeline to a port near Mangaluru — an efficient, cost-effective technology that makes remote Western Ghats deposits commercially feasible.
  1. Market linkages: Being a 100% export unit, Kudremukh is directly linked to international markets via Mangaluru port, ensuring consistent demand and revenue.

Without the pipeline technology and export market access, the deposit's remote location would make it economically unviable.

Explanation

Examiners expect you to address all three factors named in the question — transport technology, market linkages, and implicitly, ore quality. The key textbook fact is the slurry pipeline to Mangaluru port — this is a frequently tested specific detail. Avoid writing generally about minerals; anchor every point to Kudremukh. Three marks = three distinct points, each tied to the example.
