Q71. Match List-I (Lake/Wetland) with List-II (Ecological Status / Conservation Feature) and select the correct answer using the codes given below:
Lake/Wetland
Ecological Status / Conservation Feature
A. Sambhar Lake
i. Recognised as a Ramsar Wetland Site in 1990
B. Keoladeo Ghana
ii. Recognised as a Ramsar Wetland Site in 1981
C. Mansagar Lake
iii. Restored Jal Mahal integrating private-public partnership
D. Ana Sagar Lake
iv. Historic urban lake facing severe encroachment and siltation
Explanation
Rajasthan’s wetlands and lakes have varying conservation statuses. Sambhar Lake and Keoladeo Ghana are both recognized Ramsar sites, designated in 1990 and 1981 respectively. Mansagar Lake in Jaipur is known for its restoration via a public-private partnership. Meanwhile, Ana Sagar in Ajmer faces typical challenges of urban lakes, such as siltation and encroachment. These classifications help prioritize national conservation efforts.

Q72. Identify the incorrect statement regarding lake conservation programs in Rajasthan.
Explanation
The National Lake Conservation Plan is a Centrally Sponsored Scheme, meaning it is not funded entirely by the state government. Funding is typically shared between the Central and State governments in a specific ratio. While the state implements the projects, financial support and policy guidelines come from the national level to ensure the systematic restoration and conservation of critical aquatic ecosystems.

Q73. Given below are two statements, one labelled as Assertion (A) and the other as Reason (R): Assertion (A): Most freshwater lakes in the Aravalli and southern regions of Rajasthan are artificial rather than natural. Reason (R): They were historically constructed by local rulers to conserve rainwater for drinking and irrigation purposes in a semi-arid climate. Select the correct answer from the codes given below:
Explanation
Many freshwater lakes in the Aravalli and southern regions of Rajasthan are indeed man-made rather than natural. Historically, local rulers constructed these reservoirs by damming seasonal streams to harvest and store rainwater. This practice was a strategic response to the state’s semi-arid climate and erratic rainfall, ensuring a reliable supply of water for drinking and irrigation throughout the entire year.

Q74. In which year was the Rajasthan State Wetland Authority constituted to enforce the Wetland (Conservation and Management) Rules in the state?
Explanation
The Rajasthan State Wetland Authority was officially constituted in 2019. Its primary mandate is to implement and enforce the Wetland Rules within the state. This body is responsible for identifying, notifying, and protecting critical wetlands from encroachment and pollution. The establishment of this authority marked a significant step toward the institutionalized and systematic conservation of Rajasthan’s diverse and fragile aquatic ecosystems.

Q75. Under the Wetland (Conservation and Management) Rules implemented in Rajasthan, which of the following activities is strictly prohibited within the notified boundary of a wetland?
Explanation
Under the Wetland Rules, setting up new industries or expanding existing ones within a notified wetland’s boundary is strictly prohibited. This rule aims to prevent chemical pollution and physical encroachment that could destroy the delicate aquatic habitat. Other activities like traditional fishing or scientific research are generally permitted or regulated, as they do not typically cause the same level of environmental harm.

Q76. Which of the following broad classifications most accurately describes the general climatic characteristics of Rajasthan as a whole?
Explanation
Rajasthan’s climate is predominantly characterized by extreme temperatures and sparse rainfall. Large parts of the state fall under the arid and semi-arid categories due to its geographical location. The Thar Desert dictates these characteristics, leading to a continental climate with significant temperature variations between summer and winter seasons across the diverse topography of the region.

Q77. What is the primary meteorological effect of the extreme heating of the Thar Desert during the summer season in Rajasthan?
Explanation
During the summer months, the intense heating of the sandy terrain in the Thar Desert creates a deep low-pressure zone. This meteorological phenomenon is crucial as it acts as a thermal engine, drawing moisture-laden winds from the high-pressure areas over the Indian Ocean. This pressure gradient facilitates the advancement of the southwest monsoon into northern India.

Q78. Consider the following statements regarding the temperature patterns in Rajasthan: Statement I: The western parts of Rajasthan experience a higher diurnal range of temperature compared to the eastern parts. Statement II: The sandy soil of the Thar desert heats up rapidly during the day and cools down rapidly at night. Select the correct response from the options given below:
Explanation
Western Rajasthan experiences a higher diurnal temperature range primarily because of its sandy soil. Sand has a low specific heat capacity, causing it to heat up very rapidly under solar radiation during the day and lose heat quickly through radiation at night. This physical property of the desert surface leads to extreme fluctuations between daytime highs and nighttime lows.

Q79. Match List I (Koeppen’s Climatic Region) with List II (Representative District) and select the correct answer using the options below. List I: (Koeppen’s Climatic Region) A. BWhw B. BShw C. Cwg D. Aw List II: (Representative District) i. Dungarpur ii. Dausa iii. Sikar iv. Jaisalmer
Explanation
Koeppen’s classification identifies Jaisalmer as part of the arid BWhw region, while Sikar falls under the semi-arid BShw category. Dausa is situated in the sub-humid Cwg region, and Dungarpur belongs to the tropical Aw zone. These classifications reflect the distinct variations in precipitation and temperature patterns observed across the diverse geographical landscapes of the state of Rajasthan.

Q80. Which of the following statements regarding the temperature zones of Rajasthan is incorrect?
Explanation
In reality, winter temperatures in the arid and semi-arid regions of western Rajasthan frequently dip below the freezing point. During intense cold waves, frost formation is a common phenomenon in districts like Churu and Bikaner. The sandy soil’s rapid heat loss at night facilitates these sub-zero temperatures, contradicting the claim that they never fall below zero degrees Celsius.

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.
