Pictures of the moon’s surface show that it is pockmarked with round walled shapes known as craters. What caused them is a bit of a mystery. Men have landed on the moon several times. A lot of satellites have been sent to look at it. Yet scientists still cannot say for certain what caused the craters. The moon does not have an atmosphere like the earths. This makes it easier for meteorites to smash into its surface. Meteorites heading towards earth often break up as they pass through the atmosphere. So meteorites probably caused a good many of the moon’s craters.
A lot of the craters are huge. Some measure over 150 kilometres across. Others are so tiny they cannot be seen from earth. So another theory is that some craters may have been formed by volcanic activity bubbling up from inside the moon.
Most likely both meteorites and internal eruptions were responsible. But we still do not know for certain.
