So he did not find that song childish? Sarah was surprised, her muggle grandmother used to be a teacher and she used to teach it to her students.
Sarah raised her hand,"a meteoroid is natural debris from the solar system. the size of a meteoroid i varies, from the size of sand to the size of a boulder. The path it makes as it enters a planets' atmosphere is called a meteor. If it survives impact it is called a meteorite. If many meteors are coming in quick succesion and from what seems to be the same spot in space it is called a meteor shower. It is funny that I really see them, as apparently 15,000 tonnes of meteoroids, space dust and debris enter the atmosphere of earth every year. Perhaps they coming in from less populated regions."
