Which one among the following pairs of mine and mineral is NOT correctly matched?
- A.Bailadila : Iron Ore
- B.Zawar : Zinc
- C.Ghatsila : Copper
- D.Kudremukh : Bauxite
Correct answer
Explanation
The correct answer is D, Kudremukh : Bauxite. Kudremukh in Karnataka is known for iron ore, not bauxite, so this pair is wrong.
The Kudremukh hills in the Western Ghats of Chikkamagaluru district hold large deposits of magnetite iron ore. The Kudremukh Iron Ore Company mined there and sent slurry by pipeline to Mangaluru port for export, until mining stopped in 2005 to protect the Kudremukh National Park. India's main bauxite comes from the Panchpatmali hills of Koraput in Odisha, along with Jharkhand, Chhattisgarh and Gujarat.
A is correct: Bailadila in Dantewada, Chhattisgarh, has some of India's finest haematite iron ore, much of it exported to Japan through Visakhapatnam.
B is correct: the Zawar mines near Udaipur, Rajasthan, are India's leading source of zinc and lead.
C is correct: Ghatsila in the Singhbhum copper belt of Jharkhand is a major centre of copper mining and smelting.
Exam tip: Bailadila and Kudremukh, iron ore; Zawar, zinc and lead; Ghatsila and Khetri, copper; Koraput, bauxite.

Read the full explanation →Consider the following statements with reference to earthquakes:
1. Collapse earthquakes are most common.
2. Tsunamis are waves generated by the tremors and not an earthquake in itself.
3. High magnitude earthquakes i.e. 8+ are quite rare whereas 'tiny' types occur almost every minute.
Which of the statements given above are correct?
- A.1 and 2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Show answer
Statement 1 is false because tectonic earthquakes, not collapse earthquakes, are the most common type. Earthquakes are grouped by cause: tectonic (sliding of rocks along a fault), volcanic, collapse (the roofs of underground mines or caverns falling in), explosion (from nuclear or chemical blasts) and reservoir-induced.

1. Earthquakes largely occur along the converging plate boundaries.
2. Point of origin of earthquake in lithosphere is known as focus/hypocentre.
3. Intensity of earthquake decreases with distance from the epicentre.
4. Epicentre of earthquake always remains over continents only.
Select the correct answer using the code given below.
- A.1 and 2 only
- B.1, 2 and 3
- C.2 and 3 only
- D.1 and 4
