There are great round holes on the moon. They look like big lakes. They are called craters.
There are more than 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.

you weigh on earth. If you weigh 50 kilos, on the moon you will weigh only a little more than 8

very long steps as well. And…Maybe you won’t sleep very well because one day on the moon lasts
for two weeks.
