Q91. Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Assertion (A): Mount Abu experiences much lower summer temperatures compared to the surrounding plains of the Jalore and Sirohi districts. Reason (R): Temperature decreases with an increase in altitude at a standard lapse rate. Select the correct answer from the options given below:
Explanation
Mount Abu experiences significantly cooler summer temperatures compared to the nearby low-lying plains of Jalore and Sirohi. This is a direct consequence of the environmental lapse rate, which states that atmospheric temperature decreases as altitude increases. Because Mount Abu is situated at a high elevation in the Aravalli Range, it remains much cooler than the surrounding regions despite the intense summer heat.

Q92. Based on long-term climate data, during which period is the incidence of drought historically highest in the arid districts of western Rajasthan?
Explanation
Long-term climatic data for western Rajasthan shows that drought is a frequent and recurring phenomenon. In the most arid districts, meteorological or agricultural drought occurs on average once every two to three years. This high frequency is due to the extreme variability and unreliability of the monsoon rains in the Thar Desert region, making water security a constant challenge for the local population.

Q93. Consider the following statements regarding the general climatic regions of Rajasthan: I. The Arid climate region covers approximately 20% of the state’s total area. II. The Semi-arid region is characterized by steppe-type vegetation and thorny bushes. III. The Sub-humid region is largely concentrated along the Aravalli axis. IV. The Humid region features a mix of deciduous trees and relatively stable agricultural conditions. V. The Very Humid region in Rajasthan is extensive, covering the entire northern plains. Which of the above statement(s) is/are incorrect?
Explanation
Statement I is incorrect because the Arid region covers approximately 60% of the state’s area, not 20%. Statement V is also incorrect because the Very Humid region is not extensive; it is limited to specific areas in the southeast and the Mount Abu region, rather than covering the entire northern plains. The descriptions for the Semi-arid, Sub-humid, and Humid regions are generally accurate.

Q94. Bikaner district has no flowing rivers. From a climatological perspective, which combination of factors best explains this geographical reality?
Explanation
Bikaner district lacks flowing rivers due to its extreme arid environment. The region receives very little annual rainfall, which is insufficient to sustain permanent water bodies. Furthermore, the highly porous sandy soil causes any surface water to infiltrate quickly. Combined with exceptionally high potential evapotranspiration rates driven by heat and wind, moisture is lost before it can form stable drainage channels or river systems.

Q95. Identify the correctly paired climatic code of Koeppen with its descriptive meaning for Rajasthan.
Explanation
In Koeppen’s classification system, the code BWhw specifically represents a hot desert climate characterized by low precipitation and dry winters. This classification is perfectly suited for the western parts of Rajasthan, including the Thar Desert.

Q96. Which is the most appropriate reason why the southeastern part of Rajasthan (Hadoti region) receives significantly higher rainfall than the western part?
Explanation
The Hadoti region gets more rain because it is on the windward side of the moisture-laden Bay of Bengal winds that enter from the east.

Q97. Match List I (Local Weather Phenomenon) with List II (Primary Characteristic) and select the correct answer using the options below. List I: (Local Weather Phenomenon) A. Loo B. Andhi C. Mawath D. Purvaiya List II: (Primary Characteristic) i. Winter rainfall from Mediterranean cyclonic disturbances ii. Hot, dry, scorching summer winds iii. Moisture-bearing winds from the east iv. Violent, dust-raising summer storms lowering temperatures temporarily
Explanation
Loo is a hot, dry summer wind, Andhi is a violent dust-raising storm, Mawath is winter rain from Mediterranean disturbances and Purvaiya is a moisture-bearing easterly wind. This gives A-ii, B-iv, C-i, D-iii.

Q98. Select the odd one out concerning districts primarily influenced by the Arabian Sea branch of the Southwest monsoon.
Explanation
Banswara, Dungarpur and Sirohi (Mount Abu) are influenced by the Arabian Sea branch of the monsoon. Hanumangarh in the north-west is not, so it is the odd one out.

Q99. Consider the following statements regarding the factors influencing Rajasthan’s climate: I. The vast expanse of the Thar desert acts as a major heat source, fundamentally driving local wind circulations. II. The absence of dense forest cover over large parts of the state exacerbates temperature extremes. III. The latitudinal position of the state places it entirely outside the influence of the subtropical high-pressure belt. IV. The presence of the Aravalli range enhances rainfall uniformly across both its eastern and western flanks. Which of the above statement(s) is/are incorrect?
Explanation
The Thar desert is a heat source and the lack of forest cover increases temperature extremes, so I and II are correct. Rajasthan is under the influence of the subtropical high-pressure belt and the Aravalli range does not raise rainfall uniformly on both sides, so III and IV are incorrect.

Q100. The general climatic classification divides the state of Rajasthan into how many distinct climatic regions based primarily on rainfall and temperature patterns?
Explanation
Rajasthan is divided into five climatic regions on the basis of rainfall and temperature: arid, semi-arid, sub-humid, humid and very humid, the last being the Mount Abu area.

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?
