Because it has no atmosphere

Not only the Moon, Earth is hot during the day and cold at night too. But the Earth has an atmosphere that evens out the differences, the Moon doesn't, so the differences are more extreme.

Jason T has a very good explanation.
The lunar day is around 28 earth days long, so each part of the moon is exposed to the sun for 14 earth days and then shielded from it for another 14 earth days. The earths atmosphere not only helps retain heat from the sun, but it also reflects a lot as well. Since there is no atmosphere to reflect sunlight from the moon, it heats up more than the earth does.

Because it has no atmosphere, and day and night last two weeks each. Without an atmosphere the surface of the Moon gets two weeks of uninterrupted, full-strength sunlight, so it gets very hot. On the other hand, when the sun is no longer shining on the surface the lack of atmosphere means there is nothing to prevent the heat from radiating away into space. After two weeks of receiving no heat whatsoever from the sun the surface gets very cold.

The moon has no atmosphere to hold in warmth. right here on earth, our particularly dense atmosphere includes carbon dioxide and water vapor that capture the solar's warmth for the time of the day so our planet may well be insulated at night. Sorta like a cosmic blanket concept. The moon has no such cocoon of air, as a result for the time of the day, there's no longer something to shelter the moon's floor from the radiation of the solar, and there at the instant are not any gases to capture the warmth for the night. the effect of this may well be a sweltering 250 stages F. for the time of the day, and a frigid -250 stages F. at night.

during the day, light rays from the sun hit the surface of the moon .Since it has no atmosphere, the surface gets heated up. Similarly at night, the moon away from the sun. D ue to the lack of atmosphere again, the surface looses the heat gained and thus the temprature falls drastically.
i wonder, how old are you?

lack of atmosphere causes far greater shifts in day night temperatures than on earth.

because its atmosphere is so thin?
