Concept:Lines that connect points of equal salinity on an ocean map are known as isohalines.
Explanation:The term "isohaline" comes from "iso" meaning equal and "haline" meaning salt.
On a map of the ocean, these lines link all locations where the salinity (salt concentration) is the same.
For example, an isohaline might pass through all points with salinity of
35 parts per thousand.
Options like isobars refer to equal pressure, not salinity.
Option C "isosalines" is not the standard term used in geography.
Therefore, the correct geographical name for these lines is isohalines.
Answer:A. isohalines
