Question

Water near the equator is warmer than water at the poles. Which sentence explains why?

A) deep sea vents pumps steam into oceans unevenly
B) upwelling spew warm water toward the equator
C) dense, salty water tends to hold more heat
D) the sun heats earth and it ocean unevenly

*Environmental science*

Answer 1

Hi there!

You will have already be known that the sun's rays are closest to the equatorial regions than the polar regions. So the stronger heat rays reach the equator first, heating it's water faster. Within the span of time when the rays reach the polar areas (poles), the sun rays become slanted, leading it into the ocean waters.

Also, the sharpness or intensity of the rays gets weakened, thereby heating the water of polar regions less.

Using this fact, we can say that the rays falling near the equator heats the water more than the rays heating the water at poles.

Hence, we can say that D) The sun heats earth and it ocean unevenly will be your answer.

Thank you !
