Question

Where would the temperature of the ocean's surface water be the lowest?

(a) areas close to the equator

(b) areas with a low density

(c) areas with a high salinity

(d) areas at high latitudes

i think its a... 0_0

Answer 1

Option (D)

Step-by-step explanation:

The temperature of the sea surface water (ocean surface water) is maximum at the equatorial region and minimum at the polar region. It is because the equatorial region receives the maximum amount of sunlight as a result of which the sea water temperature remains relatively high.

On the other hand, the sea surface water temperature is low at the polar region (higher altitude region) because the sunlight is not able to reach this place, and even if they reach it cannot cause much effect of heat on the water.

The salinity of the water is maximum at the the mid latitudinal region and minimum at the equator and at the poles of both the hemisphere.

The density of the water is maximum at the poles and minimum at the equator.

Thus, the sea surface temperature is lowest at higher latitudinal areas, specially in and around the polar region.

Hence, the correct answer is option (D).

Answer 2

The correct answer is option C, areas with a high salinity

Step-by-step explanation:

The higher the density of the ocean water, the lower will be the temperature. The highly saline ocean water thus exists in the polar regions than the tropic regions. Due to high density the cold water seeps down and thus it further becomes cooler while a low density ocean water remains at the surface and possess additional heat
