Question

If salinity increased at the poles , water near the poles would ?

Answer 1

Plato Answer:

A. increase in density, so it would sink more rapidly.

Answer 2

According to Plato, there would be increase in density and the water near the poles would presumably sink rapidly. More density means that there's a higher percentage of saline water. The saltiness and temperature of water determines density, so if salinity increased at the poles, water near the poles would sink rapidly.
