- Question 1 of 10
1. Question
1 pointsCategory: GeographyThe term “Yarrabubba Crater” is often seen in news is located in which of the following place?
Correct
The Yarrabubba crater is an asteroid impact structure, the eroded remnant of a former impact crater, situated in the Mid West Western Australia.
- It as a precise age of 2.229 billion years, it is the oldest known impact structure on Earth.
- According to recent study, Australia‘s Yarrabubba asteroid impact crater is oldest on earth and it may have been responsible for ending an ice age.
- Other older asteroid crater are the Vredefort Dome in South Africa (2.023 billion years old) and Canada‘s Sudbury Basin (1.850 billion years old).
- These are the only other precisely dated Precambrian impact structures that are currently known.
- Originally stretching roughly 70 km wide, the Yarrabubba resisted reliable estimates of its age because of erosion and plate tectonics.
- It is now an elliptical structure with a diameter of approximately 20 km.

3. Question
1 pointsConsider the following statements regarding the “Indian Ocean Dipole”:
- It is an irregular oscillation of sea-surface temperatures in which the western Indian Ocean becomes alternately warmer and then colder than the eastern part of the ocean.
- It affects the strength of monsoons over the Indian subcontinent.
Which of the statements given above is/are correct?
Correct
The Indian Ocean Dipole (IOD), also known as the Indian Niño, is an irregular oscillation of sea-surface temperatures in which the western Indian Ocean becomes alternately warmer (positive phase) and then colder (negative phase) than the eastern part of the ocean.
- The IOD involves a periodic oscillation of sea-surface temperatures (SST), between “positive”, “neutral” and “negative” phases.
- The IOD also affects the strength of monsoons over the Indian subcontinent.
- The IOD is one aspect of the general cycle of global climate, interacting with similar phenomena like the El Niño-Southern Oscillation (ENSO) in the Pacific Ocean.

4. Question
1 pointsThe term “Limiting Factor – Vehicle” is often seen in news is related to which of the following?
Correct
The Limiting Factor is a two-man vessel that is capable of diving to full ocean depth.
- It is the world’s first and only manned-submersible that will be certified for dives to 11,000 m / 36,000 ft.
- A team of scientists is preparing to dive deep into the depths of the Indian Ocean — into a “Midnight Zone” where light barely reaches but life still thrives.
- Scientists from the British-led Nekton Mission plan to survey wildlife and gauge the effects of climate change in the unexplored area.
- Working with the Seychelles and Maldives governments, the five-week expedition is targeting seamounts — vast underwater mountains that rise thousands of meters from the sea floor.
- To explore such inhospitable depths, Nekton scientists will board one of the world’s most advanced submersibles, called “Limiting Factor.”

5. Question
1 pointsThe terms “Ciara & Sabina” is often seen in news is related to which of the following?
Correct
On February 9 – 2020, a major storm hit northern Europe, disrupting travel and public events in the region.
- The storm, named ‘Ciara’ in the UK, is expected to hit Ireland, France, Belgium, the Netherlands, Switzerland, and Germany. In Germany, it is being referred to as ‘Sabine’.
- The storm has two names because there isn’t yet a pan-European system in place for labeling weather systems.
- Hurricane-force winds up to 129 kph battered the country, the strongest since 2013. Trains, flights, and ferries were cancelled and weather warnings were issued at several places.

6. Question
1 pointsWhich of the following pair (s) is/are correctly matched?
Gas Field : Nation
- Jebel Ali : United Arab Emirates
- North Field : Russia
- South Pars : Qatar
Select the correct answer using the code given below:
Correct
On February 3 – 2020, the United Arab Emirates (UAE) announced it had discovered a new natural gas field with 80 trillion standard cubic feet (tscf) of shallow gas resources.
- The gas field discovery, reportedly the largest in the world since 2005, holds the potential of helping UAE’s gas self-sufficiency, reducing its reliance on neighbouring Qatar for the fuel.
- The reservoir, named ‘Jebel Ali’, is located between the emirates of Dubai and Abu Dhabi, which along with five other emirates form the UAE.
- According to officials, it spans around 5,000 square kilometres.
- According to a Bloomberg report, the gas find is the largest since the discovery of the Galkynysh field in Turkmenistan in 2005.
- At 80 tscf, the new reservoir would now be ranked the fourth largest by size in the Middle East, behind the North Field in Qatar, South Pars in Iran, and the Bab field in Abu Dhabi.
- The Qatari and Iranian fields are part of the same deposit.

9. Question
1 pointsAccording to the Forest Survey of India (FSI) – 2019, which state recorded highest number of forest fire alerts?
Correct
About 21.40% of forest cover in India is prone to fires, with forests in the north-eastern region and central India being the most vulnerable, the 2019 report by the Forest Survey of India (FSI) has said.
- The forest fire points (FFP) identified during the 13 years add up to 2,77,758.
- They were analysed using a moderate resolution imaging spectroradiometer (MODIS) by overlaying the points coverage over the grid coverage of 5 km x 5 km.
- The total number of alerts issued for each state based on MODIS data from November 2018 to June 2019 was 29,547 and interestingly, Mizoram, a small State, recorded the highest number of fire alerts (2,795).
- The seven States of the north-eastern region accounted for 10,210 fire alerts, which make up about one-third of alerts in the country.
- Central Indian States also recorded a high number of forest fire alerts, with Madhya Pradesh accounting for 2,723 alerts; Maharashtra 2,516; Odisha 2,213 and Chattisgarh 1,008 alerts between November 2018 to June 2019.

- Question 10 of 10
10. Question
1 pointsConsider the following statements:
- Mesosphere lies above Stratosphere and extends up-to a height of 120km.
- The ionosphere contains electrically charged particles known as ions, and hence, it is known as ionosphere.
- The stratosphere extends up to a height of 50 km and it contains the ozone layer.
Which of the statements given above is/are correct?
Correct
The stratosphere is found above the tropo-pause and extends up to a height of 50 km. One important feature of the stratosphere is that it contains the ozone layer.
- This layer absorbs ultra-violet radiation and shields life on the earth from intense, harmful form of energy.
- The mesosphere lies above the stratosphere, which extends up to a height of 80 km.
- In this layer, once again, temperature starts decreasing with the increase in altitude and reaches up to minus 100°C at the height of 80 km.
- The upper limit of mesosphere is known as the mesopause. The ionosphere is located between 80 and 400 km above the mesopause.
It contains electrically charged particles known as ions, and hence, it is known as ionosphere. Radio waves transmitted from the earth are reflected back to the earth by this layer.
