Why do some rocks come from space?

Some rocks come from space as a result of cosmic events, such as asteroid collisions, volcanic eruptions on other celestial bodies, or the remnants of comets. These rocks, known as meteorites, enter Earth's atmosphere and survive the journey to land on our planet. They provide valuable insights into the formation of the solar system and the composition of other celestial bodies. Studying these extraterrestrial rocks helps scientists understand the history of our universe.
