the mississippi river flows into the atlantic ocean at the gulf of mexico. what can you conclude about the salinity of ocean water near the mouth of the river? (2 points)
the salinity will be higher than in ocean water far from the river’s mouth.
the salinity will be lower than in ocean water far from the river’s mouth.
the salinity will be the same as in ocean water far from the river’s mouth.
the salinity will sometimes be higher and sometimes be lower than in ocean water far from the river’s mouth.

Explanation:

River water is fresh (low salinity) and flows into the ocean. When the Mississippi River's fresh water mixes with ocean water at its mouth, it dilutes the ocean water. So the salinity near the river's mouth (where fresh water is added) should be lower than in ocean water far from the mouth (where there's less fresh - water dilution).

Answer:

B. The salinity will be lower than in ocean water far from the river’s mouth.
