Question

Salt concentration (Salinity) of the sea measured in parts per thousand is:

• A. 0 – 5
• B. 30 – 70
• C. 10 – 15
• D. 30 – 35

Answer 1

The correct option is D 30 – 35

Salinity of the sea :

Amount of salt dissolved in a water body is called salinity. It is measured in parts per thousand (ppt). Sea water contains a lot of salt such as sodium chloride, potassium chloride and many more.

Salinity of different water bodies can vary greatly:

• The salinity of seawater is 30-35 parts per thousand.
• The salinity is less than 5 parts per thousand in inland waters.
• The salinity of some hypersaline lagoons is more than 100 parts per thousand

Final answer:
d.) 30 – 35
