isotopic evidence

Isotopic evidence refers to the study of isotopes, which are variations of elements that have the same number of protons but different numbers of neutrons. Scientists examine these isotopes in natural materials, such as rocks, water, or fossils, to understand age, origin, and processes that have occurred over time. For instance, different isotopes of carbon can reveal information about ancient climate conditions or dietary habits of organisms. This technique is widely used in fields like geology, archaeology, and paleontology to gain insights into Earth’s history and the evolution of life.
