3. Which of the following country is the largest producer of Uranium?
[A] Australia
[B] Kazakhstan
[C] Russia
[D] France
Show Answer
Correct Answer: B [Kazakhstan]
Notes:Kazakhstan is the world’s largest uranium producer. In 2022, Kazakhstan produced 21,227 metric tons of uranium, which accounted for 43% of the world’s uranium supply. Kazakhstan has been a major uranium producer for over 50 years. Other top uranium producers include:
- Canada, which produced 7,351 metric tons of uranium in 2022
- Namibia, which produced 11% of the world’s uranium in 2022
- Uzbekistan, which produced about 3,300 metric tons of uranium in 2022
Kazakhstan has 12% of the world’s uranium deposits. The Chu-Sarysu basin in central Kazakhstan accounts for over half of the country’s known uranium resources.
4. Which among the following is the only landlocked country in ASEAN?
[A] Thailand
[B] Laos
[C] Vietnam
[D] Cambodia
Show Answer
Correct Answer: B [Laos]
Notes:
Laos is the only landlocked country in ASEAN. The Association of Southeast Asian Nations is a regional intergovernmental organization comprising ten countries in Southeast Asia.
5. Which among the following South East Asian country is Landlocked?
[A] Cambodia
[B] Brunei
[C] Laos
[D] Vietnam
Show Answer
Correct Answer: C [Laos]

Laos is a landlocked south east Asian country. Laos capital is Vientiane. Its currency is lao Kip.
6. The current El-Nino year of 2015, has been often termed as "double El Nino" by many scientists. Which of the following best defines "double El-Nino"?
[A] Two consecutive years of the concentration of warm water in the Pacific Ocean.
[B] Combination of El-Nino with Indian Ocean Dipole to give multiple impacts.
[C] El-Nino in combination with poor local weather.
[D] El-Nino year not immediately followed by La-Nina year.
Show Answer
Correct Answer: A [Two consecutive years of the concentration of warm water in the Pacific Ocean.]
Notes:
Normally, the warm water from an El Nino spreads across the Pacific and cools as it evaporates. The increased moisture in the air leads to thunderstorms and tropical storms. That hasn’t happened as much as anticipated over the last year. Infact, two consecutive years of the concentration of warm water in the Pacific Ocean has disturbed the weather across different parts of the world.
7. Seasons on Earth are caused due to:
[A] Earth’s rotation
[B] Earth’s axial tilt on its axis
[C] Earth’s axial tilt and its rotation on its axis
[D] Earth’s axial tilt and its revolution around the Sun
Show Answer
Correct Answer: D [ Earth’s axial tilt and its revolution around the Sun]
Notes:
Fourth option is the correct answer. Earth’s axial tilt is around 23.44 degrees.
8. Which of the following is the reason due to which the weight of an object at the poles is greater than at the equator? (UPSC Prelims 1979).
[A] It is because of the shape of the earth
[B] The attraction of the moon is maximum at the earth’s surface
[C] The attraction of the sun is maximum at the earth’s surface
[D] Gravitational pull is more at the poles
Show Answer
Correct Answer: D [Gravitational pull is more at the poles]
Notes:Weight of an object=mg. If g is less then the weight is less. The value of ‘g’ is less at the equator because of the following two reasons:
- The shape of the earth is not perfectly spherical. That’s why the radius at the equator is more. Thus, g is less at equator.
- The centrifugal force is opposite to g at equator. Since forces are vectors and the resultant vector is minimum when the vectors are opposite to each other, g is minimum at equator. If the earth rotated extremely fast then the centrifugal force and g would have cancelled each other out at equator. Earth is spinning with more angular velocity at equator. It decreases as we move towards the poles. This increased angular velocity at equator produces outward centrifugal force which decreases the effect of g.
Hence the weight of an object is less at equator while it is maximum at poles.
9. Which of the following causes Earthquakes?
[A] Volcanic eruptions
[B] Landslides
[C] Cyclones
[D] Movement of a part of earth’s surface on account of the faulting of rocks
Show Answer
Correct Answer: D [Movement of a part of earth’s surface on account of the faulting of rocks]
Notes:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.
10. Which of the following is the brightest heavenly body in the evening/night sky? (UPSC Prelims 1991)
[A] Jupiter
[B] Saturn
[C] Mars
[D] Venus
Show Answer
Correct Answer: D [Venus]
Notes:
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.
