- Question 1 of 5
1. Question
With reference to cold-water corals, consider the following statements:
1. There are more cold-water coral reefs than tropical reefs in the oceans.
2. Cold-water corals requires zooxanthellae to survive.
3. Lophelia reefs are coldwater corals which can host species of fish and invertebrates.
Which of the statements given above is/are
correct?CorrectAnswer: C
Statement 2 is incorrect:
Like tropical corals, they provide habitat to other species, but deep-water corals do
not require zooxanthellae to survive.IncorrectAnswer: C

not require zooxanthellae to survive. - Question 2 of 5
2. Question
With reference to Polar Vortex, consider the following statements:
1. It is a whirling cone of high pressure over the poles.
2. When it becomes strong, a wave of cold air is pushed southwards always.
3. The term vortex refers to counter-clockwise flow of air.
Which of the statements given above is/are correct?CorrectAnswer: C
Statement 1 is incorrect. Polar vortex is described as a whirling cone of low pressure over the poles. Statement 2 is incorrect. Normally, when the vortex is strong and healthy, it helps to keep a current of air (the jet stream) travelling around the globe in almost a circular path. This current keeps the cold air up north and warm air down south. When the vortex becomes weak there is a lack of a strong low-pressure system, resulting in jet stream losing the hold to keep it in line, and becoming wavy and all of a sudden, a river of cold air is pushed down south.

3. Question
Consider the following statements:
1. Thunderstorms and Tornadoes are atmosphere’s adjustments where unstable atmosphere returns to stable state.
2. Thunderstorms are common in middle latitudes whereas Tornadoes are common in high latitudes.
Which of the statements given above is/are correct?CorrectAnswer: A
Statement 2 is incorrect. Thunderstorms and Tornadoes are both common in mid latitudes. In fact, Tornadoes are severe thunderstorms having spiralling wind descending like a trunk of an elephant with great force, with very low pressure at the centre, causing massive destruction on its way.

4. Question
In the context of role of Tropical easterly jet stream on Indian Monsoons, consider the following statements:
1. These streams play an important role in the reversal of upper air circulation patterns.
2. The streams steer the tropical depressions into India.
3. The tracks of these streams in India are the areas of highest rainfall in India.
Which of the statements given above is/are correct?CorrectAnswer: D
All the statements are correct.IncorrectAnswer: D
All the statements are correct. - Question 5 of 5
5. Question
Consider the following statements:
1. The rate of decrease of temperature of oceans with depths is lower at the equator than at the poles.
2. The winds blowing from the land towards the ocean helps in upwelling of cold water at coast.
3. The enclosed seas in the high latitudes record relatively higher temperature than the open seas.
Which of the statements given below is/are correct?CorrectAnswer: B
Statement 1 is incorrect. The rate of decrease of temperature with depths is greater at the equator than at the poles. Though the surface temperature of the seas decreases from equator towards the poles but the temperature at the ocean bottoms is uniform from the equator towards the pole, which means that the rate of decrease of temperature with increasing depth is more rapid near the equator than towards the poles.
Statement 3 is incorrect. The enclosed seas in the low latitudes record relatively higher temperature than the open seas. Whereas the enclosed seas in the high latitudes have lower temperature than the open seas.IncorrectAnswer: B
