Pls asap why does a coastal area have less variation in temperature than a noncoastal area? temperatures feel cool all year round due to the duration of daylight. temperatures change from warm to cool depending on the season. the temperatures on land change more rapidly than temperatures on water. the air is warm because warm water moves from the equator to the poles.

The a coastal area have less variation in temperature than a non-coastal area because of the high heat capacity of water.  

In coastal areas, water of the ocean absorb the heat slowly during the day and release heat slowly in the night.

This is because the heat capacity of water is high, this means the water need more energy to increase its temperature and vise versa.

Therefore, the a coastal area have less variation in temperature than a non-coastal area because of the high heat capacity of water.

Very interesting question. What happens is:

Waters temperature varies less and slower than the airs temperature.

Which means that if during the year we have temperatures of 15ºC, 40Cº and 31ºC, the air will always be on those temperatures (reason for which thermometers are on the air, not on the water).

If we had those same temperatures, in the end the water will be hotter (because it would be "recovering" its temperature). - Mainly because there were more hotter temperatures than cold ones (remember the comparison is made with air temperature).

Therefore, the answer is:

C.
