Q12. Based on the relationship between area and population in Rajasthan’s physiographic divisions, which region is characterized by the highest population density?
Explanation
Among all the physiographic divisions of Rajasthan, the Eastern Plains have the highest population density. This is primarily due to the fertile alluvial soil deposited by the Banas and Chambal rivers, which supports intensive agriculture. Additionally, the region enjoys a more favorable climate and better water availability compared to the arid west, attracting large-scale human settlement and extensive urban development.
Q13. Consider the following statements about Rajasthan’s interstate boundaries:
I. Rajasthan shares its longest interstate border with Madhya Pradesh.
II. The border with Punjab is the shortest, measuring 89 km.
III. Bhilwara is the district that shares the longest interstate boundary overall.
IV. Jhalawar shares an interstate boundary with Madhya Pradesh.
V. Two districts of Rajasthan share a boundary with Uttar Pradesh.
Which of the above statements is/are correct?
I. Rajasthan shares its longest interstate border with Madhya Pradesh.
II. The border with Punjab is the shortest, measuring 89 km.
III. Bhilwara is the district that shares the longest interstate boundary overall.
IV. Jhalawar shares an interstate boundary with Madhya Pradesh.
V. Two districts of Rajasthan share a boundary with Uttar Pradesh.
Which of the above statements is/are correct?
Explanation
Rajasthan’s longest interstate border is with Madhya Pradesh, while Punjab has the shortest. Jhalawar district shares the longest individual interstate boundary, specifically with Madhya Pradesh. Three districts, Deeg, Bharatpur, and Dholpur, border Uttar Pradesh. These boundaries are essential for regional administration, as they define the spatial limits through which resources, people, and trade move between Rajasthan and its neighboring Indian states.
Q14. What does the geological term "Bap Boulder Bed" located near Jodhpur signify in the context of Rajasthan’s geological history?
Explanation
The Bap Boulder Bed near Jodhpur is evidence of extensive glaciation in the Permo-Carboniferous period. The boulders were carried there by ice, which shows that the region once had a very cold climate.
Q15. Match the geographical terms associated with the desert morphology in List I with their specific definitions in List II.
Select the correct code:
| Term | Definition |
|---|---|
| A. Hamada | i. A sandy desert |
| B. Reg | ii. A rocky, stone-paved desert lacking sand |
| C. Erg | iii. A mixed desert of stones and sand |
| D. Runn/Tat | iv. A shallow saline depression or temporary lake |
Explanation
Desert landforms in Rajasthan are classified by their surface characteristics. A Hamada is a barren, rocky desert. A Reg consists of a mixture of sand and gravel. An Erg is the classic sandy desert dominated by dunes. A Runn or Tat refers to a shallow saline depression that often becomes a temporary lake after rainfall, illustrating the desert’s varied and complex geomorphology.
Q16. Out of the total 692 kilometers length of the Aravalli Range from Palanpur (Gujarat) to Delhi, approximately what length lies within the borders of Rajasthan?
Explanation
The Aravalli Range spans a total length of approximately 692 kilometers from Palanpur in Gujarat to Delhi. Out of this total, about 550 kilometers lie within the state of Rajasthan, accounting for roughly 80 percent of the range’s total length. This dominance makes the Aravallis the most significant topographical feature influencing the state’s climate, drainage, and rich mineral distribution.
Q17. The Southeastern Plateau (Hadoti region) is structurally divided into two major sub-units. Which of the following correctly identifies these two sub-units?
Explanation
The Southeastern Plateau, or Hadoti region, is structurally composed of two distinct sub-units: the Vindhyan Scarplands and the Deccan Lava Plateau. The scarplands are characterized by massive sandstone cliffs, while the lava plateau is formed from basaltic volcanic activity. Together, these formations create a rugged landscape that differs significantly from the sandy plains and the ancient fold mountains found elsewhere in Rajasthan.
Q18. The following question consists of two statements, an Assertion (A) and a Reason (R). Read the statements carefully and select the correct answer.
Assertion (A): The Western Sandy Plains of Rajasthan experience a very high diurnal range of temperature.
Reason (R): The sandy soil of the region is characterized by a high specific heat capacity, meaning it absorbs and loses heat extremely slowly.
Assertion (A): The Western Sandy Plains of Rajasthan experience a very high diurnal range of temperature.
Reason (R): The sandy soil of the region is characterized by a high specific heat capacity, meaning it absorbs and loses heat extremely slowly.
Explanation
The Western Sandy Plains experience a very high diurnal range of temperature, meaning the difference between day and night temperatures is extreme. However, this is because sand has a low specific heat capacity, allowing it to heat up very quickly during the day and cool down rapidly at night. The assertion is true, but the reasoning provided is scientifically incorrect.
Q19. Nakki Lake, a prominent high-altitude geological feature of Rajasthan, is situated within which specific physiographic formation?
Explanation
Nakki Lake is a unique high-altitude lake situated in Mount Abu, within the Sirohi district. It is located on the Mount Abu Batholith, which is a massive igneous rock formation within the southern Aravalli Range. According to local legend, the lake was dug by the nails of gods, but geologically it represents a significant feature in the state’s rugged mountain topography and relief.
Q20. Consider the following broad categories of geological formations found in Rajasthan:
I. Quaternary Aeolian Deposits (Sand Dunes)
II. Aravalli Supergroup
III. Deccan Traps
IV. Vindhyan Supergroup
Which of the following represents the correct chronological order from youngest (most recent) to oldest?
I. Quaternary Aeolian Deposits (Sand Dunes)
II. Aravalli Supergroup
III. Deccan Traps
IV. Vindhyan Supergroup
Which of the following represents the correct chronological order from youngest (most recent) to oldest?
Explanation
Rajasthan’s geological history spans billions of years. The oldest formations are the Aravalli Supergroup rocks. These were followed by the sedimentary Vindhyan Supergroup and the volcanic Deccan Traps. The most recent features are the Quaternary aeolian deposits, including the sand dunes that continue to shift across the Thar Desert today. This sequence reflects the long and complex structural evolution of the state.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.
