Previous Year Question
Consider the following information:
Waterfall | Region | River | |
1. | Dhuandhar | Malwa | Narmada |
2. | Hundru | Chota Nagpur | Subarnarekha |
3. | Gersoppa | Western Ghats | Netravati |
In how many of the above rows is the given information correctly matched?
Only one
Only two
All three
None of these
Correct Answer: A
Detailed Solution
Only Row 2—Hundru Falls–Chota Nagpur–Subarnarekha River is completely correctly matched.
1. Dhuandhar–Malwa–Narmada: Incorrect
Dhuandhar Falls is situated near Bhedaghat in Jabalpur district of Madhya Pradesh.
It is formed by the Narmada River. Therefore, the river is correctly mentioned.
However, Jabalpur is situated in the Mahakoshal region, not in the Malwa region.
Consequently, the entire row becomes incorrect.
At this place, the Narmada flows through a narrow gorge composed of marble rocks.
The fine spray produced by the falling water appears like smoke, giving the waterfall its name ‘Dhuandhar’.
The Narmada is a west-flowing river occupying a fault-controlled rift valley. It originates from the Amarkantak Plateau and drains into the Gulf of Khambhat.
2. Hundru–Chota Nagpur–Subarnarekha: Correct
Hundru Falls is situated near Ranchi in the Chota Nagpur Plateau of Jharkhand.
It is formed by the Subarnarekha River.
At Hundru, the Subarnarekha descends approximately 98 metres over a plateau edge.
The river originates in the Ranchi region and flows through Jharkhand, West Bengal and Odisha.
It ultimately drains into the Bay of Bengal.
The name Subarnarekha means ‘streak of gold’. Fine particles of gold have traditionally been reported from the sands of some stretches of the river.
Numerous waterfalls occur in the Chota Nagpur Plateau because rivers encounter sudden breaks in slope and alternating hard and soft rock formations.
3. Gersoppa–Western Ghats–Netravati: Incorrect
Gersoppa Falls is presently better known as Jog Falls.
It is situated in the Western Ghats region of Karnataka. Therefore, the region is correctly mentioned.
However, it is formed by the Sharavathi River, not the Netravati River.
Hence, the entire row is incorrect.
At Jog Falls, the Sharavathi descends approximately 253 metres.
Its four principal cascades are traditionally known as Raja, Rani, Roarer and Rocket.
The Sharavathi is a west-flowing river that drains into the Arabian Sea.
The Netravati is also west-flowing, but it enters the Arabian Sea near Mangaluru; it does not form Jog Falls.
Conclusion
Row | Status | Reason |
1 | Incorrect | Dhuandhar is on the Narmada but not in Malwa |
2 | Correct | Hundru–Chota Nagpur–Subarnarekha is correct |
3 | Incorrect | Gersoppa is on the Sharavathi, not the Netravati |
