[A] They are the deepest parts of the oceans.
[B] They cover nearly 40% of the ocean floor.
[C] They run parallel to the bordering fold mountains or the island chains.
[D] They are associated with active volcanoes and strong earthquakes.
Show Answer
Correct Answer: B [They cover nearly 40% of the ocean floor.]
Notes:
Oceanic trenches, some of the deepest spots on earth, are long, narrow, relatively steep-sided depressions in the deep sea. They run parallel to the bordering fold mountains or the island chains. They are associated with active volcanoes and strong earthquakes. This makes them very significant in the study of plate movements.
Abyssal Plains cover nearly 40% of the ocean floor.
24. Which zone of ocean water does not receive adequate sunrays?
[A] Photic
[B] Euphotic
[C] Aphotic
[D] Surface
Show Answer
Correct Answer: C [Aphotic ]
Notes:
The Aphotic zone extends from 200 m to the ocean bottom. This zone does not receive adequate sunrays.
Photic or euphotic zone extends from the upper surface to ~200 m. The photic zone receives adequate solar insolation.
25. Which among the following joins places of equal salinity at the sea surface?
[A] Isobar
[B] Isocline
[C] Isohaline
[D] Isotherm
Show Answer
Correct Answer: C [Isohaline]
Notes:
The spatial distribution of surface salinity of the oceans and the seas is represented by Isohalines which are the lines that join the places of equal salinity at the sea surface.

28. Which among the following statements is/are correct about commercial fishing?
- The most favourable areas for growth of fish are the deep waters of the oceans.
- Convergence of warm and cold currents also promotes blending of water making fishing less remunerative.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: D [Neither 1 & 2]
Notes:
Commercial fishing activity is largely concentrated in the oceans of the Northern Hemisphere. The most favourable areas for growth of fish are the shallow waters of the oceans. Convergence of warm and cold currents also promotes blending of water beneficial to fish culture through the process of cooler water displacing warmer water. These areas are favourable for fishing activities.
29. Which among the following statements is/are correct about Commercial Fishing?
- The continental shelf areas of the oceans are the most important fish producing areas.
- Some of the commercially harvested fish such as herring and mackeral live directly on plankton.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:
Commercial fishing activity is largely concentrated in the oceans of the Northern Hemisphere. The most favourable areas for growth of fish are the shallow waters of the oceans. The continental shelf areas of the oceans are the most important fish producing areas. These microscopic plant and associated animal organisms are together called plankton. Some of the commercially harvested fish such as herring and mackeral live directly on plankton while others such as tuna and shark prey on those eating plankton.
30. Which among the following countries is/are the leading producers of nitrogenous fertilisers?
- US
- India
