There are no rivers and no lakes. At night, it is very cold. The temperature goes down 1510 C below zero. But during the day the temperature rises to 1000 C above zero.

Good evening. Welcome to our Science For Fun Program. This week, we’ve received a lot of questions asking about life on the moon.
There are great round holes on the moon. They look like big lakes. They are called craters. There are more then 30,000 craters on the moon. There are also high mountains. The highest mountains on the moon are about 26,000 feet or 8,000 meters high.
So, is there life on the moon? I’ll leave the questions for you to answer yourself.
And here is something very interesting to know: on the moon you weigh one sixth of what you weigh on earth. If you weigh 50 kilos, on the moon you will weigh only a little more than 8 kilos. You will be able to jump very high, even higher than an Olympic Champion. You can take very long steps as well. And … may be you want won’t sleep very well because one day on the moon lasts for 2 weeks.
Questions:
a) Why are there no sounds on the moon?
b) How many creatures are there on the moon?
c) How much will you weigh on the moon if you weigh
50 kilos on the earth?
d) Will you sleep very well on the moon? why/? Why not?
Because there is no air on the moon.
There are about 30,000 creatures on the moon.
If I weigh 50 kilos, I’ll weigh only a little more than 8 kilos.
No, we won’t. Because one day lasts for two weeks
on the moon.
