Question

What is one reason that the surface water at the equator is less dense than

the surface water at the poles?

Answer 1

The density of ocean water is so varied, that while there may be a generally considered variation due to temperature, taking random samples in a wide variety of places, thus you can distinguish no real pattern.

Step-by-step explanation:
