Question

Ocean water at the poles is cold, and dense, due to high salinity.


True or false?

Answer 1

At high latitudes, ocean water receives less sunlight. Thus, the surface waters in the Arctic and Antarctica are not warmed much; in fact they are very cold

so false

Answer 2

The statement on ocean water is a false.

Step-by-step explanation:

Ocean water in poles are cold and dense because it receives only forty percentage of heat compared to heat received by equator region. The cold water is more dense and little bit heavier than warm water.

The deep ocean receives less sunlight resulting in less warming. Cold water (denser) sinks below warm water resulting in coldness in deep. Since, the ocean is not standing still, variation in "temperature and density" constantly replace the bottom layer with cold water.
