Question

Quizplus · Accepted Answer

The main reason for the extreme temperature difference between day and night on the moon is the lack of a significant atmosphere to trap heat. During the day, the surface is exposed to direct sunlight and absorbs a lot of energy, which raises the temperature to about 200°C. However, during the long lunar night, there is nothing to trap or reflect the energy absorbed during the day, so it all escapes into space, causing the temperature to drop to about -270°C. The other options given do not fully explain this phenomenon.
