Isotope analysis is a scientific technique used to determine the composition of isotopes in various materials, which can provide valuable insights into processes such as climate change, geological formations, and biological systems. By measuring the ratios of isotopes, researchers can trace the origins and transformations of substances, helping to reconstruct past environments and understand current ecological dynamics. This method is particularly useful in fields like paleoclimatology and forensic science, where it aids in identifying sources of pollution or verifying the authenticity of artifacts. Isotope analysis has become an essential tool for scientists seeking to unravel complex environmental and biological questions.
