Question

Quizplus · Accepted Answer

Air and soil temperatures at or very close to the ground surface are more variable due to direct exposure to sunlight, radiation, and other surface effects, whereas air temperatures measured at standard heights (about 1.5 to 2 meters above the ground) are moderated by the mixing of air masses and are less subject to rapid changes.
