27. Where do tropical cyclones originate?
- Over the Sea
- Over the land
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2

28. Which among the following statements is/are correct about Ocean Temperature?
- The rate of decrease of temperature with increasing depth from equator towards the poles is not uniform.
- The polar seas have only one layer of cold water mass from the ocean surface to the deep ocean floor.

[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:
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.
The polar seas have only one layer of cold water mass from the ocean surface to the deep ocean floor.
29. Which among the following pairs is/are correctly matched?
- Apogee – Moon’s orbit is farthest from the earth.
- Aphelion – The earth is closest to the sun.
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: A [Only 1]
Notes:
Apogee: When the moon’s orbit is farthest from the earth, it is called as apogee. Tidal ranges will be much less than the average during this period.
Aphelion: It is the position where the earth is farthest from the sun (around July 4th). Tidal ranges are much less than the average during this period.
