Correct option is A
Correct Answer: (A) 35 parts per thousand
Explanation:
→ Salinity refers to the amount of dissolved salts in seawater.
→ The average ocean salinity is 35 parts per thousand (ppt).
→ It means 35 grams of salt per 1000 grams of seawater.
→ Salinity varies due to evaporation and freshwater inflow.
→ Therefore, option (A) is correct.
Information Booster:
→ Salinity affects marine life distribution.
→ High evaporation increases salinity.
→ River inflow reduces salinity.
→ Salinity influences ocean density and circulation.
→ It plays a role in climate regulation.
