Question

Which of these are controlling factors of density of seawater?
i) Temperature
ii) Pressure
iii) Salinity

• A. a) i only
• B. b) i and ii
• C. c) ii and iii
• D. d) All of the above
  

Answer 1

The correct option is D d) All of the above


d)
Explanation: Temperature is directly related to thermal expansion which controls the density of the water. Temp increases-density decreases and vice versa
Pressure has compressive effects which affects the density of water.Pressure increases-density increases and vice versa.
Salinity adds dissolved substances which determines the density of the water. Salinity increases- density increases and vice versa.
