How do meteorites tell us about the composition of earth?

Meteorites provide valuable insight into Earth's composition by serving as remnants of the early solar system. Many meteorites, particularly chondrites, are composed of materials that have not undergone significant alteration since their formation, allowing scientists to study the primordial building blocks of planets. By analyzing their isotopic and elemental compositions, researchers can infer the processes that shaped Earth and its differentiation into core, mantle, and crust. Additionally, some meteorites are thought to originate from bodies that share similar materials with Earth, further enhancing our understanding of our planet's geological history.
