Question

Quizplus · Accepted Answer

Mercury's slow rotation (taking about 59 Earth days to complete one rotation) contributes to extreme variations in its surface temperature. This is because one side of the planet faces the Sun for an extended period, heating up significantly, while the other side remains in darkness and cools down. This results in a large temperature difference between the day and night sides of the planet.
