Some students believe that the intensity of sunlight at a place does not change from day to day during the year

Misconception RESEARCH REVIEW

Sunlight-based explanations for seasons involve sunlight centrally but do not consider the distance of the earth, the tilt, or its orientation. Rather, solar energy is described as being directed or isolated to specific locations.

    There must be another explanation for the seasonal changes. Here is a loop showing the variation of the solar radiation arriving over a year (repeated a few times, so you can see the pattern).

    The explanation depends on the amount each square metre of Earth is warmed by the Sun; most in the summer, least in the winter.
