Question

What impact does sunlight have on the marine environment?

A Light from the sun shows animals where they need to migrate.
B Sunlight makes colors more visible, improving animal communication.
C The heat from the sun increases the temperature of the water.
D The water temperature is kept constant throughout different depths due to the sun.

Answer 1

The answer to this is C because when the sun shines on the water it tends to heat up because water is like a mirror it reflects the light of it but in doing so it is heating up the water making the water really hot.

Answer 2

D The water temperature is kept constant throughout different depths due to the sun.

Step-by-step explanation:

Solar radiations serve to keep the water temperature constant throughout the depth of ocean. The surface water temperature is maintained up to the range of 25-28 degree C. Similarly, the temperature at depths of 1000 m is maintained up to 4-5 degree C. The process of convection and mixing as caused by surface perturbation maintain the temperature distribution in marine ecosystems.
