Detailed explanation-1: -iron meteorites: which are almost completely made of metal. stony-iron meteorites: which have nearly equal amounts of metal and silicate crystals. stony meteorites: which mostly have silicate minerals.
Detailed explanation-2: -Meteorites are fragments of rock or metal that fall to Earth from space. They are very rare, but many people find unusual rocks or pieces of metal and wonder if they might have found a meteorite.
Detailed explanation-3: -Meteorites are classified according to a variety of characteristics, especially mineralogical, petrological, chemical, and isotopic properties.
Detailed explanation-4: -More than 95% of all meteorites contain iron-nickel (FeNi) metal. As a consequence, meteorites have concentrations of nickel that are much greater than that of nearly any terrestrial rock. “Iron-nickel” means that the metal is mostly iron but it also contains 5-30% nickel.
