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

A

`10 - 5`

B

`30 - 70`

C

`0-5`

D

`30 - 35`

Text Solution

Verified by Experts

The correct Answer is:
D
Salinity of water bodies is generally measured in parts per thousand. It determines what kind of organisms can live in it. Salinity of the sea is 30-35 parts per thousand, while for inland waters, and some lagoons is less than 5 and more than 100, respectively. Fresh water animals generally cannot live for long in sea water and vice versa because of osmotic problems.
