What causes water to become denser when it is carried to the poles by surface currents? increased temperature and increased sali
Anarel [89]

Answer:

The answer is decreased temperature and increased salinity

Explanation:

It is what is known as the thermohaline circulation

The thermohaline circulation moves the water slowly. This water moves mainly due to differences in its relative density. Much denser water sinks over water that is less dense. Two factors impact the density of seawater: temperature and salinity.

Cold water is denser than hot water:

-Water cools when it loses heat, it occurs at high latitudes.

-Water is heated when it receives energy from the sun, at low latitudes.

Saltier water is much denser than water that has less salt:

-Sea water becomes salty if the evaporation rate increases.

-Sea water becomes less salty if there is a water inlet over the sea.
