Since the moon does not have an atmosphere as thick as ours, many scientists have suggested that some of the craters on the moon may have resulted from the impacts of meteors. Meteors that impact Earth are called meteorites. These meteorites are composed primarily of rocks and dust. Meteorites are categorized according to their composition. Some of these categories include iron, stony iron and chondrite.
Most meteorites fall into the chondrite category.
Many of the materials found in meteorites are also found in the Earth s mantle and crust of. The mantle is the dense molten core of the Earth which we see as the lava that erupts from volcanoes. The crust is the surface of Earth that we live on. In 1908 a meteor struck Siberia. While no crater was created by the impact of the meteorite, trees were flattened and the damage that resulted spanned a 60 kilometer area.
