Question

What is the salt content range for brackish water bodies and estuaries?

• A. Less than 5 ppt
• B. 35 ppt or above
• C. Exactly 3.5 per cent
• D. Between 5 and 35 ppt

Answer 1

Answer:

D. Between 5 and 35 ppt

• The salt content of fresh bodies is very low, always less than 5 ppt (parts per thousand)

• The water bodies containing salt concentration equal to or above that of sea water (i.e., 35 ppt or above) are called as saline water bodies or marine water bodies.

• Estuaries and brackish water bodies have salt content between 5 to 35 ppt.
