Question 1 of 8
1. Question
Q1. {S&T – Space} Which of the following best describes the term Hyperspectral Imaging?
Correct
Explanation
Option (b) is correct
Hyperspectral imaging (HSI) is a technique that analyses a wide spectrum of light instead of just assigning primary colours (red, green, blue) to each pixel.
The collected spectra form an image, with each pixel including a complete spectrum. Images are captured and analysed using 100s of wavelengths rather than 10s of wavelengths, as done currently.
Recently, Google-backed India’s space tech startup Pixxel achieved a milestone by launching three hyperspectral imaging satellites aboard a SpaceX rocket.
Answer: (b) A technique that analyses a wide spectrum of light instead of just assigning primary colours to each pixel; Difficulty Level: Medium

Explanation
Pair 1 is correct
The Gulf of Aden is in the Indian Ocean, between Yemen on the south coast of the Arabian Peninsula and Somalia in Africa.
The Gulf runs in a west-east direction — roughly 900 kilometres long and 500 kilometres wide. It is an important waterway for transporting Persian Gulf oil.
Together with the Red Sea, which connects within the northwest through the Bab el Mandeb, it forms an essential oil transport route between Europe and the Far East.
In recent years, the Gulf has received a lot of attention due to piracy, terrorism, and refugee smuggling.
Pair 2 is correct
Andaman Sea is a marginal sea of the northeastern Indian Ocean.
It is bounded to the north by the Irrawaddy River delta of Myanmar (Burma); to the east by peninsular Myanmar, Thailand, and Malaysia; to the south by the Indonesian island of Sumatra and by the Strait of Malacca; and to the west by the Andaman and Nicobar Islands.

Q8. {Envi – Species} Consider the following species:
Killer Whale
Short-finned Pilot Whale
Long-finned Pilot Whale
Sea otters
Which of the above species are found in every ocean in the world?
Correct
Explanation
Species 1 is correct
Often referred to as wolves of the sea, the killer whale, also known as orca, is the ocean’s top predator.
It is the largest member of the Delphinidae family or dolphins.
Known for their intelligence, orcas are highly skilled hunters and can coordinate tactics during hunts.
They are fast swimmers, reaching speeds up to 54 km per hour.
Distribution: Found in every ocean in the world, they are the most widely distributed of all cetaceans (whales and dolphins). They are found in both open seas and coastal waters.
Physical description: They have a large black body, a white underside, a white patch above and behind the eye, ‘saddle patch’ behind the dorsal fin.
Conservation Status:IUCN:Data Deficient
Species 2 and 3 are incorrect
Short-finned Pilot Whale (Globicephala macrorhynchus) are found in tropical and warm-temperate waters.
Long-finned Pilot Whale (Globicephala melas), found in colder waters, are further subdivided into three sub-species: the Southern long-finned pilot whale (G. m. edwardii), the North Atlantic long-finned pilot whale (G. m. melas), and the now extinct North Pacific long-finned pilot whale (G. m. un-named subsp.).
Sea Otters are water mammals found along the coasts of the Pacific Ocean in North America and Asia.
Unlike other marine mammals, they have no blubber to protect them from hypothermia.
Sea otters are key players in the health of the kelp forests they inhabit.
IUCN Status: Endangered.
