Meteorite formation is the scientific study of how meteorites are formed and the processes involved in their formation. Meteorites are pieces of rock and metal that have fallen to Earth from outer space, often originating from asteroids or other bodies in the solar system. There are several different types of meteorites, each formed through different processes such as impact melting, brecciation, and thermal metamorphism. Understanding the formation of meteorites can provide valuable insights into the early history of our solar system and the processes that have shaped it over billions of years.
