Q2. Read the given statements and select the correct answer from the options provided: Given below are two statements, one labelled as
Assertion (A) and the other labelled as Reason (R):
Assertion (A): The Degana mines in Nagaur district represent a strategically significant mineral deposit in India.
Reason (R): Rajasthan possesses the only major workable deposit of tungsten in India, primarily found as wolframite ore.
Assertion (A) and the other labelled as Reason (R):
Assertion (A): The Degana mines in Nagaur district represent a strategically significant mineral deposit in India.
Reason (R): Rajasthan possesses the only major workable deposit of tungsten in India, primarily found as wolframite ore.
Explanation
The Degana mines located in the Nagaur district of Rajasthan are recognized as a strategically vital site for tungsten production in India. Rajasthan holds the distinction of possessing the only major workable deposit of tungsten ore, specifically wolframite. This mineral is essential for manufacturing hard steel alloys and defense equipment, justifying its strategic importance to the nation.
Q3. Read the given statements and select the correct answer from the options provided:
Statement I: Rampura-Agucha is globally recognized as one of the world’s largest zinc mines.
Statement II: The Rampura-Agucha mine is situated in the Udaipur district of Rajasthan.
Statement I: Rampura-Agucha is globally recognized as one of the world’s largest zinc mines.
Statement II: The Rampura-Agucha mine is situated in the Udaipur district of Rajasthan.
Explanation
Rampura-Agucha is globally renowned as one of the world’s largest and richest zinc-producing mines. However, geographical records indicate that this major mining operation is located in the Bhilwara district, not Udaipur. While Udaipur is famous for the Zawar mines, Rampura-Agucha remains the primary source of lead and zinc concentrates within the Bhilwara region of Rajasthan.
Q4. Match the items in List I with those in List II and select the correct answer using the options provided:
| Mineral | Major Mining Area in Rajasthan |
|---|---|
| A. Lead and Zinc | i. Morija-Banol |
| B. Copper | ii. Degana |
| C. Tungsten | iii. Khetri |
| D. Iron Ore | iv. Zawar |
Explanation
Lead and zinc are primarily extracted from the Zawar mines in Udaipur. Copper mining is synonymous with the Khetri-Singhana belt in Jhunjhunu. Tungsten is famously produced at the Degana mines in Nagaur district. Iron ore deposits are found at Morija-Banol near Jaipur. These sites represent the most significant industrial locations for the respective minerals within the state of Rajasthan.
Q5. Identify the odd one out among the following minerals based on their classification as metallic or non-metallic minerals in Rajasthan:
Explanation
Classification of minerals separates them into metallic and non-metallic categories. Lead, zinc, and copper are all metallic minerals because they contain metal elements and are processed for metal extraction. In contrast, gypsum is a non-metallic mineral primarily composed of calcium sulfate dihydrate. It is widely used in agriculture and the construction industry rather than for metal production.
Q6. Match the items in List I with those in List II and select the correct answer using the options provided:
| Copper Mines | District |
|---|---|
| A. Khetri-Singhana | i. Alwar |
| B. Kho-Dariba | ii. Bhilwara |
| C. Pur-Dariba | iii. Jhunjhunu |
| D. Bhagot-ka-Bas | iv. Sikar |
Explanation
Khetri-Singhana is in Jhunjhunu, Kho-Dariba in Alwar, Pur-Dariba in Bhilwara and Bhagot-ka-Bas in Sikar. This gives A-iii, B-i, C-ii, D-iv.
Q7. Identify the correctly matched pair regarding non-metallic minerals and their major deposit area in Rajasthan:
Explanation
Rock phosphate is found at Jhamarkotra near Udaipur. The other pairs are wrong: Mica is not linked with Makrana, which is known for marble.
Q8. The world-famous white marble used in the construction of the Taj Mahal and the Victoria Memorial was primarily sourced from which of the following mining locations in Rajasthan?
Explanation
The white marble of the Taj Mahal and the Victoria Memorial came from Makrana in the Nagaur district of Rajasthan.
Q9. Which of the following is the most appropriate reason for the continuous emphasis on mineral beneficiation in Rajasthan’s mining sector?
Explanation
Beneficiation upgrades low-grade ores to the standards industry needs. It is emphasised because high-grade ores are depleting.
Q10. Consider the following prominent mineral mining centres of Rajasthan and arrange them from North to South geographically:
I. Khetri (Jhunjhunu)
II. Rampura-Agucha (Bhilwara)
III. Zawar (Udaipur)
IV. Rajpura-Dariba (Rajsamand)
Which of the following represents the correct sequence?
I. Khetri (Jhunjhunu)
II. Rampura-Agucha (Bhilwara)
III. Zawar (Udaipur)
IV. Rajpura-Dariba (Rajsamand)
Which of the following represents the correct sequence?
Explanation
From north to south the centres are Khetri in Jhunjhunu, Rampura-Agucha in Bhilwara, Rajpura-Dariba in Rajsamand and Zawar in Udaipur.Answer key for these questions
