Q22. Consider the following statements regarding Guru Shikhar:
I. It is located in the Mount Abu region of the Sirohi district.
II. Col. James Tod referred to it as the ‘Peak of the Saints’ (Santon Ka Shikhar).
III. It lies in the northern section of the Aravalli Range.
Which of the above statements is/are correct?
I. It is located in the Mount Abu region of the Sirohi district.
II. Col. James Tod referred to it as the ‘Peak of the Saints’ (Santon Ka Shikhar).
III. It lies in the northern section of the Aravalli Range.
Which of the above statements is/are correct?
Explanation
Guru Shikhar is located in the Mount Abu region of Sirohi district and was aptly named the "Peak of the Saints" by Col. James Tod. Standing at 1722 meters, it is the highest point in Rajasthan. However, it is situated in the southern part of the Aravalli Range, not the northern section, which is characterized by much lower and fragmented elevations.
Q23. In the context of the Thar Desert classification, the region surrounding Jaisalmer, Ramgarh, and Pokhran that consists predominantly of exposed sedimentary rocks without significant sand cover is known as:
Explanation
The specific type of desert found around Jaisalmer, Ramgarh, and Pokhran, which is characterized by exposed sedimentary rocks and a lack of significant sand cover, is known as a Hamada. This rocky terrain stands in contrast to the shifting dunes of the sandy Erg desert.
Q24. Which of the following statements best provides the definition of a "Reg" in the geographical context of Rajasthan?
Explanation
In the geographical context of Rajasthan, a "Reg" refers to a stony desert surface. It is a desert plain composed of a mixture of gravel, pebbles, and sand. This landform is created when wind removes the finer sand particles, leaving behind a layer of coarser materials. It represents one of the three major types of desert surfaces found throughout the Thar Desert.
Q25. Match the major macro-physiographic divisions in List I with their approximate percentage share of Rajasthan’s total geographical area in List II.
Select the correct code:
| Division | Percentage Area |
|---|---|
| A. Western Sandy Plains | i. 9.0% |
| B. Aravalli Range | ii. 23.3% |
| C. Eastern Plains | iii. 6.89% |
| D. Southeastern Plateau | iv. 61.11% |
Explanation
Rajasthan is divided into four major physiographic units with varying spatial coverage. The Western Sandy Plains are the largest, occupying 61.11 percent of the state. The Eastern Plains cover 23.3 percent, followed by the Aravalli Range at 9.0 percent. The Southeastern Plateau, or Hadoti region, is the smallest, accounting for 6.89 percent of the total geographical area of the state.
Q26. In the Eastern Plains of Rajasthan, areas comprised of older alluvium that are generally elevated above the flood levels of rivers are technically termed as:
Explanation
In the Eastern Plains of Rajasthan, older alluvial deposits that are situated at a higher elevation and are generally not reached by annual river floods are termed Bangar. These areas are distinct from the newer alluvium, or Khadar, which is found in lower-lying floodplains. Bangar regions are often more stable for settlements and have been under agricultural use for longer historical periods.
Q27. The physiography of Rajasthan has a profound impact on its climate. Which of the following represents the most significant climatic function of the Aravalli Range?
Explanation
The most significant climatic role of the Aravalli Range is acting as a physical barrier that restricts the eastward expansion of the Thar Desert. By spanning the state from southwest to northeast, it prevents the wind-blown sands of the western arid region from encroaching upon the more fertile and humid eastern plains, thus preserving the ecological balance of the eastern and southern districts.
Q28. Which of the following drainage systems encompasses the largest geographical area of Rajasthan?
Explanation
The internal drainage system is the most extensive in Rajasthan, covering approximately sixty percent of the state’s total area. This dominance is primarily due to the vast arid and semi-arid regions where rivers do not reach the sea. Instead, they disappear into the desert sands or flow into inland lakes, defining the unique hydrological landscape of the western desert.
Q29. Consider the following statements regarding the river systems of Rajasthan:
Explanation
The Aravalli Range serves as a significant topographical barrier and water divide in Rajasthan. It splits the drainage system into two major parts: the Arabian Sea drainage and the Bay of Bengal drainage. Rivers originating from the eastern slopes eventually join the Yamuna or Ganges, while western-slope rivers flow toward the desert or the Arabian Sea.
Q30. Consider the following statements about the internal drainage system of Rajasthan:
I. It accounts for approximately 60% of the total drainage area of the state.
II. Rivers in this system do not reach any ocean or major sea.
III. The Kantli and Kakni are prominent rivers belonging to this system.
Which of the above statements is/are correct?
I. It accounts for approximately 60% of the total drainage area of the state.
II. Rivers in this system do not reach any ocean or major sea.
III. The Kantli and Kakni are prominent rivers belonging to this system.
Which of the above statements is/are correct?
Explanation
Rajasthan’s internal drainage system characterizes the majority of the state’s hydrological profile, covering nearly sixty percent of its land. These seasonal rivers, including the Kantli, Kakni, and Ghaggar, lack enough volume to reach oceanic bodies. They terminate within the desert terrain or seasonal lakes, making them distinct components of the unique geographical and climatic conditions found in northern India.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.
