Consider Buoyancy and density. Hydrogen is the lightest element. At the highest point in heaven, you are going to find pure Hydrogen. The higher you go, the colder it gets, as the molecule binding gets lighter and lighter, creating less and less energy as they vibrates. As it gets colder, at some point gas is going to turn liquid, like the clouds bringing us rain, and even freeze. High up in the atmosphere you are going to find Magnesium mixed with hydrogen and other light elements. As this Magnesium mixture gets cold enough, it is going to turn solid, and start falling back to the earth. If a big enough chunk of Magnesium freezes high enough up in the atmosphere, it can create this light show, that you call Meteorites.
