Question 4 of 10
4. Question
1 pointsHindon River is a tributary of which major river?
Correct
Answer: b
Explanation:
A recent survey of the Hindon river has raised serious concerns about water quality, with preliminary tests showing zero dissolved oxygen (DO) levels at several locations, rendering the water “uninhabitable” for most aquatic life.
About Hindon River:
It is a tributary of the Yamuna River.
Course:
It originates in the Saharanpur district of Uttar Pradesh, in the Siwalik Hills, at an elevation of about 800 meters (2,625 feet) above sea level.
It flows across the industrial belt of Western Uttar Pradesh and Haryana before merging with the Yamuna River near Noida.
Total Length: 400 km
The river is entirely fed by rain, with a significant increase in water flow during the monsoon season.
Tributaries: The Kali (West) River and Krishni River are the main tributaries of River Hindon.
It is on the banks of this river that archeologists found traces of the Harappan civilization with sites dating back to as long as 2500 BC.
Due to urban, agricultural, and industrial waste which is being released without sufficient treatment into its waters, the Hindon is now one of the most polluted stretches in the Ganga basin.
In 2015, the Central Pollution Control Board (CPCB) found the Hindon’s pollution levels were so severe that it was declared a ‘dead river’ and ‘unfit’ even for bathing in several sections of the river.
Hence option b is the correct answer.

Question 6 of 10
6. Question
1 pointsConsider the following statements regarding Ladakh Magmatic Arc:
- It is a belt of igneous rocks in the Trans-Himalaya region.
- It was formed in the period between Jurassic to Eocene.
Which of the statements given above is/are correct?
Correct
Answer: c
Explanation:
Recently, scientists have traced the evolution of Ladakh Magmatic Arc (LMA) in North West Himalaya.
- It is a belt of igneous rocks in the Trans-Himalaya formed in the period Jurassic to Eocene– 201.3 million years ago to 33.9 Million Year (Ma).
- The LMA is a long-extinct volcanic system evolved through three major phases of geological activity over tens of millions of years.
- 160–110 million years ago: Early island arc formation
- 103–45 million years ago:Intensified magmatism during plate convergence
- Less than 45 million years ago:Post-collisional magmatic activity
- Process of Formation:
- Millions of years before the region that is now called Ladakh lay above an ocean called the Neo-Tethys Ocean.
- Below that ancient sea, giant slabs of Earth’s crust slowly plunged into the mantle in a process known as subduction leading to the formation of the Ladakh Magmatic Arc (LMA).
- Phases of Formation
- Island Arc Formation: In its earliest stage, Ladakh resembled a chain of volcanic islands rising from the Neo-Tethys Ocean.
- Represented by the Dras–Nidar Island Arc Complex (DNIAC)
- Magma primarily originated from the mantle
- Minimal contribution from subducted sediments
- Crustal Enrichment and Batholith Formation: As tectonic plates converged, the system evolved:
- Formation of large granite bodies known as the Ladakh Batholith (LB)
- Increased input from continental crust and recycled sediments
- Chemical signatures indicate deep crustal processes and magma mixing
- This phase coincides with the approaching collision between India and Eurasia.
- Post-Collision Magmatism: After the plates collided and the Neo-Tethys Ocean closed, tectonic activity continued:
- Formation of mafic dykes—vertical sheets of volcanic rock
- Magma derived from a previously enriched mantle source
- Indicates lingering tectonic and magmatic activity even after collision
- Island Arc Formation: In its earliest stage, Ladakh resembled a chain of volcanic islands rising from the Neo-Tethys Ocean.
Hence both statements are correct.
