   2. Importance 2: It is essential for smelting iron ore in the blast furnace.+0.5
   3. Major producing state, any one of: Rajasthan; Madhya Pradesh; Andhra Pradesh; Chhattisgarh; Gujarat; Karnataka; Telangana; Tamil Nadu; or any other valid major limestone-producing state.+1

   Answer: Limestone is the basic raw material for cement and is essential for smelting iron ore in the blast furnace. State: any one of Rajasthan, Madhya Pradesh, Andhra Pradesh, Chhattisgarh, Gujarat, Karnataka, Telangana or Tamil Nadu.
6. Q6Short answer·3 marks
   Why is there an urgent need for the conservation of mineral resources in India? Explain any two measures to achieve this.
   Show answer and step marks

   1. Explanation of need: Minerals are finite, non-renewable resources that take millions of years to form and are rapidly depleting due to high consumption rates.+1
   2. First measure, any one of: using improved technologies so that low-grade ores can be used at low cost; recycling metals and using scrap metal; using substitutes for scarce minerals; reducing wastage in mining and processing; planned and sustainable use of minerals; or any other valid measure.+1
   3. Second measure, a different one from the same list.+1

   Answer: Minerals are finite and non-renewable; they take millions of years to form and are being used up fast. Measures (any two of): improved technology to use low-grade ores at low cost; recycling metals and using scrap; using substitutes; reducing wastage in mining and processing; planned, sustainable use.
