6. Consider the following statements: [I.A.S (PRE) 2018]

  1. Most of the world's coral reefs are in tropical waters.
  2. More than one-third of the world's coral reefs are located in the territories of Australia, Indonesia, and the Philippines.
  3. Coral reefs host far more number of animal phyla than those hosted by tropical rainforests.

Which of the statements given above is/are correct?

Correct Answer: (d) 1, 2, and 3
Solution:
  • Coral reefs are formed by the consolidation and combination of the skeletons of marine organisms, coral, or coral polyps, and are generally confined to tropical and semi-tropical waters (mostly between 25°N to 25°S). Therefore, statement (1) is correct.
  • According to the Reef Base: A Global Information System for Coral Reef, approximately 19% of the world’s coral reef areas are in Australia and 17% in Indonesia, supporting statement (2)
  • Coral reefs contain around four times the number of animal phyla found in tropical rainforests, making statement (3) correct as well.

7. Addu Atoll are situated in which ocean? [66th B.P.S.C(Pre) (RE.EXAM) 2020]

Correct Answer: (c) Indian Ocean
Solution:Addu Atoll is situated in the Indian Ocean. It is the southernmost atoll of the Maldives. Addu Atoll is the southernmost atoll of the Maldives, located south of the equator. This unique position distinguishes it from the rest of the Maldivian archipelago. It's a strategic location in the Indian Ocean, acting as a gateway to the Arabian Sea and beyond.

India-Maldives Collaboration:

  • India and Maldives have signed contracts for the development of five eco-tourism zones in Addu Atoll. The Addu Reclamation and Shore Protection Project, along with the Addu Detour Link Bridge Project, have been inaugurated. There are plans to establish a consulate of India in Addu City and a consulate of Maldives in Bengaluru to promote people-to-people connections.

8. Consider the following statements and answer the question with the help of codes given below: [I.A.S. (Pre) 2006]

Assertion (A) : The amount of moisture in the 4 atmosphere is associated with latitude.

Reason (R) : The ability to keep the moisture in the form of water vapour is related to temperature.

Code:

Correct Answer: (a) Both (A) and (R) are true, and (R) is the correct explanation of (A).
Solution:Measure of water vapour present in the air is known as humidity. Humidity in the atmosphere is mainly related to temperature, So reason (R) is correct. Moisture/Water vapour content decreases with increase in latitude, that is, in tropical region humidity is 2.6%, at 50° latitude it is 0.9% and at 70° latitude it is 0.2% only.

The atmosphere contains 90% moisture up to 5 km height from the ground. So the Assertion (A) is also correct. Humidity is directly propositional to temperature, that is at higher temperature air can hold more water vapour than the same amount of air at lower temperatures, so reason (R) is the correct explanation assertion of (A).

9. Humid heat is experienced in summer when the weather is: [U.P.U.D.A./L.D.A. (Pre) 2002]

Correct Answer: (b) Keen
Solution:Humidity is the amount of water vapour in the air. In summer, humidity is very high therefore weather is muggy. Absolute humidity is the weight of water vapour per unit volume, usually expressed in grains per cubic foot.
