Concept:Isohalines are isolines that connect places sharing the same ocean salinity.
Explanation:On a map, an isohaline links all ocean points with equal salinity.
The word comes from "iso", meaning equal, and "haline", meaning salt.
Thus, it directly represents equal saltiness.
Isobars, however, join equal pressure points, so they are not correct.
The correct term for equal-salinity lines is isohalines.
Answer:A. isohalines
