Q92. Given below are two statements, one labeled as
Assertion (A) and the other labeled as Reason (R):
Assertion (A): Sambhar Lake is the largest inland saltwater lake in India and a major site for salt production.
Reason (R): It receives water from an endorheic basin with high summer evaporation rates, which concentrates the dissolved salts.
Assertion (A) and the other labeled as Reason (R):
Assertion (A): Sambhar Lake is the largest inland saltwater lake in India and a major site for salt production.
Reason (R): It receives water from an endorheic basin with high summer evaporation rates, which concentrates the dissolved salts.
Explanation
Sambhar Lake is the largest inland saltwater lake in India and a vital center for salt production. It functions as part of an endorheic basin, where water flows in but does not drain into the sea. The intense summer heat leads to rapid evaporation, which leaves behind concentrated dissolved salts. This natural process is the fundamental cause of the lake’s high salinity.
Q93. Identify the incorrectly matched pair of man-made reservoirs and their associated rivers:
Explanation
Several large dams in India have created massive man-made reservoirs.
Q94. Consider the following statements about Gobind Sagar reservoir:
I. It is formed by the Bhakra Dam.
II. It is situated on the river Sutlej.
III. It lies geographically in the state of Himachal Pradesh.
IV. It was named in honor of the tenth Sikh Guru, Guru Gobind Singh.
Which of the above statement(s) is/are correct?
I. It is formed by the Bhakra Dam.
II. It is situated on the river Sutlej.
III. It lies geographically in the state of Himachal Pradesh.
IV. It was named in honor of the tenth Sikh Guru, Guru Gobind Singh.
Which of the above statement(s) is/are correct?
Explanation
Gobind Sagar is a massive man-made reservoir created by the construction of the Bhakra Dam. It is located on the Sutlej river in the state of Himachal Pradesh. Named after Guru Gobind Singh, the tenth Sikh Guru, the reservoir is a critical component of the Bhakra-Nangal project. It provides water for irrigation and generates hydroelectric power for several northern states.
Q95. Which of the following is NOT a man-made reservoir?
Explanation
Man-made reservoirs are created by damming rivers for human use. Gobind Ballabh Pant Sagar, Krishnarajasagara, and Nagarjunasagar are all examples of such artificial water bodies. In contrast, Loktak Lake in Manipur is a natural freshwater lake. It is renowned for its unique ecosystem, including floating phumdis, which formed naturally over thousands of years without human intervention or dam construction.
Q96. The Nagarjunasagar reservoir, one of the earliest multi-purpose irrigation and hydro-electric projects in India, is built across which river?
Explanation
The Nagarjunasagar project is one of India’s most significant multi-purpose river valley developments. It features a massive masonry dam built across the Krishna river on the border of Telangana and Andhra Pradesh. The reservoir created by this dam supports extensive canal networks for irrigation and houses a major power plant. It was instrumental in the Green Revolution in southern India.
Q97. Match List I with List II and select the correct answer using the codes given below:
Codes:
| Fluvial Feature | Associated River/Region |
|---|---|
| A. Estuary | i. Brahmaputra (Namcha Barwa) |
| B. Delta | ii. Narmada |
| C. Ox-bow Lake | iii. Ganga (Sunderbans) |
| D. Gorge | iv. Burhi Gandak plains |
Explanation
Estuaries are common where rivers like the Narmada meet the sea in narrow inlets. Deltas, such as the Sunderbans, are formed by the Ganga and Brahmaputra at the coast. Ox-bow lakes are frequently found in the flat Burhi Gandak plains of Bihar. Gorges are deep mountain valleys, like the one formed by the Brahmaputra as it cuts through Namcha Barwa.
Q98. Consider the following statements regarding Ox-bow lakes in the Ganga plains:
I. They are formed due to the highly meandering nature of mature rivers.
II. They represent abandoned river channels.
III. They are most commonly found in the upper, youthful courses of the rivers.
IV. Kanwar Lake in Bihar is an example of a large freshwater ox-bow lake.
V. They are naturally prone to eutrophication and siltation over time.
Which of the above statement(s) is/are correct?
I. They are formed due to the highly meandering nature of mature rivers.
II. They represent abandoned river channels.
III. They are most commonly found in the upper, youthful courses of the rivers.
IV. Kanwar Lake in Bihar is an example of a large freshwater ox-bow lake.
V. They are naturally prone to eutrophication and siltation over time.
Which of the above statement(s) is/are correct?
Explanation
Ox-bow lakes are formed in the middle and lower courses of rivers where the terrain is flat. They represent old, abandoned channels created by high degrees of meandering. Kanwar Lake is a well-known example of such a feature. Over time, these lakes naturally undergo siltation and eutrophication. They are not characteristic of the youthful, high-velocity upper courses of mountain rivers.
Q99. The middle and lower Ganga plains have an abundance of ox-bow lakes. This concept implies that the terrain is:
Explanation
The presence of numerous ox-bow lakes in the middle and lower Ganga plains is a direct result of the local topography. The land in this region is remarkably flat with very gentle gradients. This lack of steepness causes the river to lose its velocity and flow in wide, sweeping meanders. These meanders are eventually cut off, creating the characteristic horseshoe-shaped lakes.
Q100. Which of the following was the first major river interlinking project to receive structural approval and implementation focus in India?
Explanation
The river interlinking project aims to connect various Indian rivers to manage water resources better. The Ken-Betwa Link was the first major project to reach the implementation phase under this national scheme. It involves transferring surplus water from the Ken river in Madhya Pradesh to the water-scarce Betwa river basin, primarily benefiting the drought-prone Bundelkhand region across two states.Answer key for these questions

Key facts from Indian Geography
- The RPSC syllabus lists Indian physiography, climate, rivers and lakes, irrigation, important crops, metallic and non-metallic minerals, and industrial regions and industries.
- Physiography and rivers are asked through locations: the highest peak of a range, the origin of a river, a lake and its state.
- Minerals and industries questions link a mineral or plant to its State, for example Khetri copper in Jhunjhunu or Bhilai steel in Chhattisgarh.
- Agriculture and irrigation questions test crops, their leading States and the major projects and disputes.
- The questions often include Rajasthan items, such as the Luni, Zawar and the Indira Gandhi Canal.
