Water near the equator is warmer than water at the poles. Which sentence explains why?
shusha [124]

Hi there!

You will have already be known that the <em>sun's rays are closest to the equatorial regions</em> <em>than</em> the <em>polar regions</em>. 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 <u>D) </u><u>T</u><u>he sun heats earth and it ocean unevenly</u> will be your answer.

Thank you !

Settlers lack the physical or financial means to transport building materials over long distances and so used what resources they could find close the area that they settled. The importance of log cabins and other dwellings in popular culture only became important in later years as movies, books, and the popular imagination associated certain types of structures with specific geographical areas.
