2. HundruChota NagpurSubarnarekha
3. GersoppaWestern GhatsNetravati

In how many of the above rows is the given information correctly matched ?

Only one

None
This question was previously asked in
UPSC IAS – 2024
Let’s examine each row:
1. Dhuandhar Waterfall, Malwa Region, Narmada River: Dhuandhar Falls are on the Narmada River near Jabalpur, Madhya Pradesh. While on the Narmada, Jabalpur is generally considered part of the Mahakoshal region or the Satpura range foothills, not the Malwa Plateau which is further west. So, the region match is incorrect.
2. Hundru Waterfall, Chota Nagpur Region, Subarnarekha River: Hundru Falls are on the Subarnarekha River near Ranchi in Jharkhand, which is part of the Chota Nagpur Plateau region. This row is correctly matched.
3. Gersoppa Waterfall, Western Ghats Region, Netravati River: Gersoppa Falls, now commonly known as Jog Falls, are located on the Sharavathi River in Shivamogga district of Karnataka, which is part of the Western Ghats. The region is correct, but the river is incorrect. Jog Falls is on the Sharavathi, not the Netravati River.
Therefore, only the second row is correctly matched.
– Dhuandhar Falls are on the Narmada River.
– Hundru Falls are on the Subarnarekha River in Chota Nagpur.
– Gersoppa/Jog Falls are on the Sharavathi River in the Western Ghats.
Jog Falls (Gersoppa Falls) is one of the highest plunge waterfalls in India. The Netravati River flows through Karnataka and is a major river of the Dakshina Kannada district, flowing westwards into the Arabian Sea.

How many of the statements given above are correct?

Only one
Only two
All three
None
This question was previously asked in
UPSC IAS – 2023
Statement 1 is correct: The Jhelum River is the primary source of water for Wular Lake and flows through it.
Statement 2 is incorrect: Kolleru Lake is located between the deltas of the Krishna and Godavari rivers and is fed by streams like Budameru and Tammileru and drainage channels, not directly by the main Krishna River.
Statement 3 is correct: Kanwar Lake (Kabar Taal) is an oxbow lake formed by the meandering activity of the Burhi Gandak River, an old channel of the Gandak River system. Oxbow lakes are indeed formed by river meandering.
– Wular Lake is a significant freshwater lake in Kashmir fed by the Jhelum.
– Kolleru Lake is an important wetland in Andhra Pradesh situated between river deltas.
– Kanwar Lake is India’s largest oxbow lake, formed by river meanders.
Wular Lake is one of the largest freshwater lakes in Asia. Kolleru Lake was designated a Ramsar site in 2002. Kanwar Lake was declared a Ramsar site in 2020.

3. Consider the following pairs : Wetland/Lake Location

Consider the following pairs :

Wetland/LakeLocation
1. Hokera WetlandPunjab

How many pairs given above are correctly matched ?

Only one pair
Only two pairs
Only three pairs
All four pairs
This question was previously asked in
UPSC IAS – 2022
Only two pairs are correctly matched: Renuka Wetland (Himachal Pradesh) and Rudrasagar Lake (Tripura).
Hokera Wetland is located in Jammu and Kashmir. Sasthamkotta Lake is located in Kerala. Renuka Wetland and Rudrasagar Lake are correctly paired with Himachal Pradesh and Tripura, respectively.
These are examples of Ramsar sites (Wetlands of International Importance) in India. Knowing the location of important wetlands and lakes is crucial for environmental geography.

4. With reference to India, Didwana, Kuchaman, Sargol and Khatu are the n

With reference to India, Didwana, Kuchaman, Sargol and Khatu are the names of

glaciers
mangrove areas
Ramsar sites
saline lakes
This question was previously asked in
UPSC IAS – 2021
Didwana, Kuchaman, Sargol, and Khatu are names of saline lakes in India.
– These names refer to lakes located in Rajasthan, India.
– Didwana Lake, Kuchaman Lake, and Khatu Lake are well-known salt lakes in the state. They are playas or temporary lakes that become saline due to evaporation in the arid and semi-arid climate.
– These lakes are important sources of salt extraction.
– The options are distinct geographical features: Glaciers are found in high mountains (e.g., Himalayas). Mangrove areas are coastal ecosystems. Ramsar sites are designated wetlands of international importance (while some of these lakes could potentially be Ramsar sites, their primary identification is as saline lakes).
Rajasthan has several inland drainage basins with saline lakes due to its topography and climatic conditions. Other notable saline lakes in Rajasthan include Sambhar Lake (India’s largest inland salt lake), Lunkaransar, and Pachpadra.

5. Which one of the following is an artificial lake ?

Which one of the following is an artificial lake ?

Kodaikanal (Tamil Nadu)

This question was previously asked in
UPSC IAS – 2018
Kodaikanal Lake is an artificial, star-shaped lake located in the town of Kodaikanal in Tamil Nadu. It was created in 1863 by Sir Vere Henry Levinge, the then Collector of Madurai, by damming a stream.
Artificial lakes are man-made reservoirs or bodies of water, whereas natural lakes are formed through geological processes like tectonic activity, volcanic activity, or glaciation.
Kolleru Lake is a large natural freshwater lake located between the Krishna and Godavari deltas in Andhra Pradesh. Nainital Lake is a natural crescent-shaped lake in Uttarakhand, believed to be of tectonic origin. Renuka Lake is a natural lake in the Sirmaur district of Himachal Pradesh, known for its religious significance and biodiversity.
