According to the conveyor belt model of ocean circulation, what usually happens when water reaches the poles?


The density of the water decreases.


The temperature of the water increases.


The salinity of the water increases.


The salinity of the water decreases.

Respuesta :

Answer: The salinity of the water increases

Explanation: When the moves from equator to the polar region the salty water starts freezing, the ice that is formed is not salty means it is a source of freshwater.

So, the water that reaches the poles becomes ice and the salinity of the water increases. This is because the poles are colder as compared to the other  parts of the globe. The water becomes ice there and its salinity increases.

Answer:

The correct answer is "The salinity of the water increases".

Explanation:

The conveyor belt model of ocean circulation refers to the system of deep-ocean circulation according to water's temperature and salinity. According to this model, the salinity of the water increases as water reaches the poles. This  is explained by salt being rejected from icebergs and other ice formations, which leaves the water in liquid form with a higher concentration of salt. The exchange of salt between ice and water influences ocean circulation around the world.
