22. Which among the following statements is/are correct about Salinity of ocean water?
- Seawater density varies with temperature, degree of salinity, and depth.
- Deep water has low density.
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:
Seawater density varies with temperature, degree of salinity, and depth.
High temperature produces low density, and high salinity produces high density.
Deep water has high density because of low temperature and because of the pressure of the overlying water.
23. Which among the following statements is/are correct about Density of ocean water?
- Seawater density increases with increasing pressure and vice versa.
- The density of sea water at the bottom of tranches is 5% lower than that of surface area.
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:
Pressure is directly positively related to ocean water through its compressive effects, seawater density increases with increasing pressure and vice versa.
The density of sea water at the bottom of tranches is 5% higher than that of surface area.
24. Which among the following statements is/are correct about the symbiotic life of Corals?
- Algae gives carbon dioxide and other substances the coral polyp needs.

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]
