Question
Why is the daytime temperature of a land surface usually warmer than the temperature of an adjacent water surface?
Solar radiation is diffused to a greater depth over water than over land
It takes three times as much energy to heat water due to water's higher specific heat
Less evaporation occurs over a land surface and more solar energy goes directly into heating the ground
All of the above
None of the above
A.Solar radiation is diffused to a greater depth over water than over land
B.It takes three times as much energy to heat water due to water's higher specific heat
C.Less evaporation occurs over a land surface and more solar energy goes directly into heating the ground
D.All of the above
E.None of the above
Explanation / Answer
Answer is :D. All of the above
EXPLANATION :
A.
Solar radiation is diffused to a greater depth over water than over land WHICH results in smaller temperature change. Solar radiation reaching the earth, some is reflected back into the atmosphere. In land reflection occurs entirely at surface and in water depends on angle of sunrays and depth of water column...
B.
It takes three times as much energy to heat water due to water's higher specific heat. As water has a much higher specific heat than land because of this amount of solar irradiation (insolation), water temperature will increase less than land temperature so much energy is needed to heat water.
C.
Less evaporation occurs over a land surface and more solar energy goes directly into heating the ground. Solar energy cannot be used in evaporation of water so water bodies tend to be less extreme than temperatures over the land surface.
