A meteorite is a natural object which falls from space/. When meteors enter the earths atmosphere, they heat up to extremely high temperatures forming meteorites/shooting stars. Most meteorites are Chondrites, being composed mainly of silicate such as Olivine and Pyroxene, while others are compised of Iron and Nickle. When meteorites impact with the earths surface, the terrestrial material. e.g. Sand, melts and recrystallises in to a new glassy mineral called a Tektite, which have a similar appearence to meteorites but are much lighter in weight.
