A student is investigating temperature changes at a nature preserve on a hot, clear day. Each hour, the student takes two temper
atures: one over the ground, and one over the water of a lake. During this investigation, which observation is the student MOST LIKELY to make? A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
B. Air over the lake will reach its highest temperature earlier in the day and will stay warm longer than air over the ground.
C. Air over the lake will reach its highest temperature later in the day and will cool off more quickly than air over the ground.
D. Air over the lake will reach its highest temperature earlier in the day and will cool off more quickly than air over the ground.
A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Explanation:
The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
This phenomenon between the differences in land and water temperature causes land sea breeze to occur.
Water has a very high specific heat capacity.
This implies it takes more heat to cause a monumental increase in its temperature.
It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.
A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.
Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
