Q342. Consider the following statements about silver production in Rajasthan:
I. Silver is primarily recovered during the smelting of zinc and lead concentrates.
II. Hindustan Zinc Limited is the principal entity responsible for silver recovery in the state.
III. Rajasthan produces only a negligible fraction (less than 1%) of India’s total silver.
Which of the above statement(s) is/are correct?
I. Silver is primarily recovered during the smelting of zinc and lead concentrates.
II. Hindustan Zinc Limited is the principal entity responsible for silver recovery in the state.
III. Rajasthan produces only a negligible fraction (less than 1%) of India’s total silver.
Which of the above statement(s) is/are correct?
Explanation
Silver in Rajasthan is primarily recovered by Hindustan Zinc Limited during the smelting of lead and zinc concentrates. The state is actually the leading producer of silver in India, contributing nearly the entire national output.
Q343. Identify the odd one out concerning the typical mode of occurrence of the following mineral deposits in Rajasthan:
Explanation
Gypsum, rock phosphate and limestone occur as sedimentary or bedded deposits, while copper occurs in metamorphic rocks as veins and lodes. So copper is the odd one out in its mode of occurrence.
Q344. Consider the following statements about the challenges faced by the mining sector in Rajasthan:
I. Depletion of high-grade ores forces industries to rely on complex beneficiation of low-grade ores.
II. Strict environmental regulations often require mining projects to undergo rigorous clearance processes.
III. Unregulated and illegal mining leads to significant losses to the state exchequer.
IV. The mining sector faces absolutely no resistance or issues regarding land acquisition from local communities.
Which of the above statement(s) is/are incorrect?
I. Depletion of high-grade ores forces industries to rely on complex beneficiation of low-grade ores.
II. Strict environmental regulations often require mining projects to undergo rigorous clearance processes.
III. Unregulated and illegal mining leads to significant losses to the state exchequer.
IV. The mining sector faces absolutely no resistance or issues regarding land acquisition from local communities.
Which of the above statement(s) is/are incorrect?
Explanation
Depletion of high-grade ores, strict environmental clearances and illegal mining losses are real problems of the mining sector. There is resistance over land acquisition from local communities, so IV is incorrect.
Q345. Identify the correctly matched pair of the mineral and its exclusive major deposit in Rajasthan:
Explanation
Degana in Nagaur is the most famous and historically significant site for tungsten in India. Lead-zinc is primarily found in Zawar and Rampura-Agucha, not Makrana. Copper is famously extracted from Khetri, not Jhamarkotra, which is a rock phosphate site. Iron ore is found in areas like Morija-Banol, whereas Sanu in Jaisalmer is renowned for high-grade limestone, making other pairings incorrect.
Q346. Which of the following statements concerning Makrana Marble is correct?
Explanation
Makrana marble is a high-quality white metamorphic rock that was the first stone from Asia to receive the Global Heritage Stone Resource designation. This status recognizes its international historical, architectural, and cultural importance. The marble remains an active resource and is pried for premium construction, sculptures, and preserving iconic monuments like the Taj Mahal rather than for industrial fertilizer use.
Q347. Consider the following prominent structural regions associated with Lead and Zinc mineralization in Rajasthan and arrange them from North to South:
I. Rampura-Agucha
II. Rajpura-Dariba
III. Zawar
Which of the following represents the correct sequence?
I. Rampura-Agucha
II. Rajpura-Dariba
III. Zawar
Which of the following represents the correct sequence?
Explanation
The major lead-zinc deposits of Rajasthan follow a North to South geographical distribution. Rampura-Agucha in the Bhilwara district is the northernmost of the three. Moving south, Rajpura-Dariba is located in the Rajsamand district. The Zawar mines in the Udaipur district represent the southernmost point in this sequence. This alignment reflects the structural trend of the mineralized belts within the state.
Q348. The large-scale extraction of Rock Phosphate from the Udaipur and Jaisalmer regions is most appropriately justified by the national necessity to produce which essential commodity?
Explanation
Rock phosphate is an essential mineral used primarily for the production of phosphatic fertilizers like Single Super Phosphate (SSP) and Diammonium Phosphate (DAP). Given India’s large agricultural sector, the extraction of rock phosphate from Udaipur and Jaisalmer is a national priority. These deposits provide the necessary phosphorus content required to improve soil fertility and enhance crop yields across the country.
Q349. Which of the following statements accurately recalls the nature of Rock Phosphate deposits found in the Jaisalmer district?
Explanation
The rock phosphate deposits found in the Jaisalmer district, particularly in the Birmania area, are characterized as low-grade sedimentary formations. Unlike the high-grade crystalline deposits found in some other regions, these occur as phosphatic nodules and layers within sedimentary rock sequences. While they are less commercially valuable than the Jhamarkotra deposits, they still represent a significant part of the state’s inventory.
Q350. The application of Gypsum in agriculture relies fundamentally on which of the following chemical concepts?
Explanation
Gypsum is used in agriculture to treat "usar" or alkaline soils. Chemically, it provides calcium ions that replace excess sodium ions on the soil particles. This replacement improves the physical structure of the soil, making it more porous and allowing for better water percolation and root growth. This fundamental chemical process is vital for reclaiming unproductive lands in arid regions.Answer key for these questions

Key facts from Rajasthan Geography
- The RPSC syllabus lists Rajasthan’s location, extent and physiography, rivers and lakes, climate, vegetation, biodiversity, soils, agriculture, livestock, irrigation, population, urbanisation and tribes.
- Many questions ask for a number or a name: the area of the State, a district’s density, the length of a canal, the home district of a mine.
- Rajasthan is the biggest State of India by area, and several chapters test the contrast between the arid west and the humid south-east.
- Minerals, irrigation and wildlife are the chapters with the most name-based questions, so keep a list of districts and projects.
- Population questions use Census 2011 figures.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Rajasthan Geography?
This page has 529 practice MCQs on Rajasthan Geography. Each has the correct answer, and most have an explanation.
Which chapters does the Rajasthan geography set cover?
Thirteen chapters: location, extent and physiography; rivers and lakes; climate; natural vegetation, biodiversity and conservation; soils; agriculture; livestock and animal husbandry; irrigation; minerals; population; urbanisation; tribes; and tourism.
Is Rajasthan geography in the RAS Prelims syllabus?
Yes. RPSC lists Geography of Rajasthan as a separate part of the syllabus, including location, rivers, climate, vegetation, soil, agriculture, livestock, irrigation, population, urbanisation and tribes, after the world and India sections.
How can I prepare Rajasthan geography quickly?
Keep a Rajasthan map and mark every river, dam, mine, sanctuary and fair that appears. Attempt each chapter, read the explanations and revise the numbers: area, population, density and canal lengths.
