[amp_mcq option1=”1 and 2 only” option2=”4 only” option3=”1 and 3 only” option4=”2, 3 and 4 only” correct=”option4″]

This question was previously asked in
UPSC IAS – 2020
The correct option is D, as Chromite, Kyanite, and Sillimanite are officially designated as major minerals in India, while Bentonite is typically classified as a minor mineral.
Minerals in India are classified as ‘major’ or ‘minor’ under the Mines and Minerals (Development and Regulation) Act, 1957. This classification impacts their regulation, such as rules for mining leases and royalty rates. The list of major and minor minerals changes based on government notifications.
As per the classification under the MMDR Act, as amended and notified periodically:
1. Bentonite: Generally classified as a Minor Mineral.
2. Chromite: Classified as a Major Mineral.
3. Kyanite: Classified as a Major Mineral.
4. Sillimanite: Classified as a Major Mineral.
Therefore, only Chromite, Kyanite, and Sillimanite among the given options are major minerals.

82. What is common to the places known as Aliyar, Isapur and Kangsabati?

What is common to the places known as Aliyar, Isapur and Kangsabati?

[amp_mcq option1=”Recently discovered uranium deposits” option2=”Tropical rain forests” option3=”Underground cave systems” option4=”Water reservoirs” correct=”option4″]

This question was previously asked in
UPSC IAS – 2019
The correct answer is D) Water reservoirs.
Aliyar, Isapur, and Kangsabati are all locations in India known for significant dams and associated water reservoirs.
– Aliyar Dam is in Tamil Nadu, creating the Aliyar Reservoir.
– Isapur Dam is in Maharashtra, forming the Isapur Reservoir on the Penganga river (also known as Yeldari Dam).
– Kangsabati Dam (or Mukutmanipur Dam) is in West Bengal, creating the Kangsabati Reservoir.
These locations are primarily recognized for their large water bodies created by dams, used for irrigation, water supply, and sometimes power generation. They are not commonly known for newly discovered uranium deposits, being part of tropical rainforests (as they span different climatic regions of India), or extensive underground cave systems. Thus, the commonality is that they are sites of water reservoirs.

  • 2. Barren Island lies about 140 km east of Great Nicobar.
  • 3. The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then.

Which of the statements given above is/are correct ?

[amp_mcq option1=”1 only” option2=”2 and 3″ option3=”3 only” option4=”1 and 3″ correct=”option1″]

This question was previously asked in
UPSC IAS – 2018
The correct answer is A) 1 only.
Let’s evaluate each statement about Barren Island volcano:
1. **The Barren Island volcano is an active volcano located in the Indian territory:** This statement is correct. Barren Island is India’s only active volcano and is located in the Andaman Sea, part of the Union Territory of Andaman and Nicobar Islands.
2. **Barren Island lies about 140 km east of Great Nicobar:** This statement is incorrect. Barren Island is located in the Andaman Sea, roughly 135-140 km northeast of Port Blair (South Andaman Island). Great Nicobar Island is located much further south, over 400 km from Barren Island.
3. **The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then:** This statement is incorrect. While there was a significant eruption in 1991 after nearly two centuries of dormancy, the volcano has erupted several times since then, including in 1995, 2005-06 (linked to the 2004 Sumatra-Andaman earthquake), and most recently exhibiting eruptions in 2017 and subsequent years. It is considered active.
Barren Island is a sub-aerial part of the volcanic arc that extends from Sumatra to Myanmar. It is uninhabited by humans. The recent eruptions highlight the ongoing volcanic activity in the region.

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.

Among the following cities, which one lies on a longitude closest to that of Delhi?

[amp_mcq option1=”Bengaluru” option2=”Hyderabad” option3=”Nagpur” option4=”Pune” correct=”option1″]

This question was previously asked in
UPSC IAS – 2018
The correct answer is A) Bengaluru.
– The question asks which city lies on a longitude closest to that of Delhi.
– Approximate longitudes of the cities are:
– Delhi: ~77.2° E
– Bengaluru: ~77.6° E
– Hyderabad: ~78.5° E
– Nagpur: ~79.1° E
– Pune: ~73.8° E
– Comparing the differences in longitude from Delhi:
– Bengaluru: |77.6 – 77.2| = 0.4°
– Hyderabad: |78.5 – 77.2| = 1.3°
– Nagpur: |79.1 – 77.2| = 1.9°
– Pune: |73.8 – 77.2| = 3.4°
– Bengaluru’s longitude (77.6° E) is closest to Delhi’s longitude (77.2° E), with a difference of only 0.4°.
Longitudes are imaginary vertical lines on Earth’s surface that run from the North Pole to the South Pole. They are used to measure positions east or west of the Prime Meridian (0° longitude). Cities on roughly the same longitude will experience local noon at approximately the same time.

90. Consider the following statements : In India, State Governments do n

Consider the following statements :

  • In India, State Governments do not have the power to auction non-coal mines.
  • Andhra Pradesh and Jharkhand do not have gold mines.
  • Rajasthan has iron ore mines.

Which of the statements given above is/are correct?

[amp_mcq option1=”1 and 2″ option2=”2 only” option3=”1 and 3″ option4=”3 only” correct=”option4″]

This question was previously asked in
UPSC IAS – 2018
The correct answer is D) 3 only.
– Statement 1 is incorrect. Under the Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act), as amended, State Governments have the power to grant mineral concessions (Prospecting License and Mining Lease) for most non-coal major minerals. The MMDR Amendment Act, 2015, made the auction of mineral concessions for specified minerals mandatory, and the auction process is conducted by the State Governments.
– Statement 2 is incorrect. Andhra Pradesh does have gold deposits and has historically mined gold (e.g., the Kolar Gold Fields extended into AP, and there are deposits like Ramagiri). Jharkhand also has known occurrences of gold, including historical small-scale mining. Therefore, claiming they “do not have gold mines” is false.
– Statement 3 is correct. Rajasthan is one of the significant iron ore producing states in India, with deposits found in districts such as Jaipur, Udaipur, Bhilwara, and Sikar.
The MMDR Act, 1957 is the principal legislation governing the mining sector in India. The Central Government has the power to regulate minerals, but the administration of minor minerals is entirely delegated to the State Governments, while major minerals (excluding coal, petroleum, etc.) are jointly regulated, with states being the grantors of concessions under the central law.
