Q102. Identify the correct statement concerning the spatial distribution of ‘Mawath’ (winter rainfall) in Rajasthan.
Explanation
Mawath, the winter rain from western disturbances, is heaviest in the north-west of Rajasthan and decreases towards the south and south-east.
Q103. Arrange the following major climatic regions of Rajasthan in the correct sequence moving generally from West to East:
I. Humid Region
II. Arid Region
III. Semi-arid Region
IV. Sub-humid Region
Select the correct sequence using the options below:
I. Humid Region
II. Arid Region
III. Semi-arid Region
IV. Sub-humid Region
Select the correct sequence using the options below:
Explanation
Moving from west to east, the climatic regions are arid, semi-arid, sub-humid and humid, as rainfall increases in that direction.
Q104. Which of the following is the most dominant factor that determines the distribution and type of natural vegetation in Rajasthan?
Explanation
Rainfall is the primary determinant of vegetation in Rajasthan because of its vast arid and semi-arid landscapes. The state’s diverse plant life, ranging from sparse desert scrub in the west to dry deciduous forests in the east, directly corresponds to the varying precipitation levels. Moisture availability dictates the physiological adaptations and distribution patterns of native flora.
Q105. Which of the following statements is incorrect regarding the desert vegetation found in Rajasthan?
Explanation
Desert plants in Rajasthan possess specialized adaptations to survive extreme heat and moisture scarcity. Instead of broad and thin leaves, which would increase water loss through transpiration, these plants typically have small, thick, or spine-modified leaves. Other features include deep root systems and waxy coatings on stems, which effectively minimize water loss and maximize survival in aridity.
Q106. Match the items in List I with those in List II and select the correct answer using the codes given below:
| Forest Type | Region in Rajasthan |
|---|---|
| A. Tropical Thorn Forests | i. Mount Abu Region |
| B. Tropical Dry Deciduous Forests | ii. Western Arid Region |
| C. Subtropical Evergreen Forests | iii. Eastern and South-Eastern Region |
| D. Mixed Deciduous Forests | iv. Southern Aravalli Region |
Explanation
The distribution of forests in Rajasthan follows distinct climatic zones. Tropical thorn forests characterize the western arid region, while tropical dry deciduous forests dominate the eastern and south-eastern areas. Subtropical evergreen forests are localized to the high-altitude Mount Abu region. Finally, mixed deciduous forests are primarily found along the southern parts of the rugged Aravalli mountain range.
Q107. What is the primary ecological effect of the severe temperature extremes and scanty rainfall in western Rajasthan?
Explanation
Western Rajasthan experiences severe temperature fluctuations and minimal rainfall, creating a harsh environment for flora. This led to the dominance of xerophytic species, which are specifically adapted to conserve water. These plants often feature deep roots, fleshy stems for storage, and modified leaves, allowing them to flourish despite the limited moisture and high evaporative demands characteristic of deserts.
Q108. Consider the following statements regarding the Tropical Thorn Forests of Rajasthan:
I. They are predominantly found in the western arid and semi-arid regions.
II. The vegetation primarily consists of trees with deep roots and thick bark.
III. These forests require an annual rainfall of more than 150 cm to thrive.
Which of the above statement(s) is/are correct?
I. They are predominantly found in the western arid and semi-arid regions.
II. The vegetation primarily consists of trees with deep roots and thick bark.
III. These forests require an annual rainfall of more than 150 cm to thrive.
Which of the above statement(s) is/are correct?
Explanation
Tropical thorn forests are native to the arid and semi-arid parts of western Rajasthan, where rainfall remains extremely low. These plants possess thick bark and deep root systems to access groundwater and withstand heat. However, they do not require 150 cm of annual rainfall; instead, they thrive in regions receiving less than 50 cm of precipitation.
Q109. What is the botanical name of the Khejri tree, the State Tree of Rajasthan?
Explanation
Prosopis cineraria is the botanical name for the Khejri tree, which is designated as the State Tree of Rajasthan. This multipurpose species is vital for the desert’s ecological balance and agricultural economy. It provides fodder, timber, and improves soil fertility through nitrogen fixation. Its cultural importance is deeply rooted in local traditions, especially within the bishnoi community.
Q110. Consider the following statements regarding tiger reserves and wildlife in Rajasthan:
I. Ranthambore was among the first nine tiger reserves established under Project Tiger.
II. Sariska successfully executed a tiger relocation programme after a local extinction.
III. Mukundra Hills is the third declared tiger reserve in Rajasthan.
IV. Desert National Park is a major breeding ground for Bengal tigers.
V. Keoladeo Ghana National Park primarily focuses on avian conservation rather than large felines.
Which of the above statement(s) is/are correct?
I. Ranthambore was among the first nine tiger reserves established under Project Tiger.
II. Sariska successfully executed a tiger relocation programme after a local extinction.
III. Mukundra Hills is the third declared tiger reserve in Rajasthan.
IV. Desert National Park is a major breeding ground for Bengal tigers.
V. Keoladeo Ghana National Park primarily focuses on avian conservation rather than large felines.
Which of the above statement(s) is/are correct?
Explanation
Ranthambore was among the first nine reserves under Project Tiger, Sariska had a successful tiger relocation, Mukundra Hills is the third tiger reserve and Keoladeo is mainly a bird sanctuary. Desert National Park is not a tiger breeding ground, so IV is wrong.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?

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.
