Question

The table lists the salinity of ocean water at four different locations. Based on the information in the table, which of these locations is most likely nearest to the mouth of a river?
A. Location 1

B. Location 2

C. Location 3

D. Location 4

Answer 1

Location 1.

Oceans have very high salinity (salt content), as they are salt water. Rivers are considered fresh water, which means they have low salinity. The water where a river and ocean means is a mix between the two salinity levels, so it makes sense that it would have a much lower salinity than other parts of the same ocean.
