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.
