Geological Dating
Definition: Geological dating is a method used by scientists to determine the age of rocks, fossils, and other geological materials. It involves analyzing the chemical composition and physical properties of these materials to estimate how long ago they were formed.
Usage Instructions: - The term "geological dating" is a noun and is often used in scientific contexts, especially in geology, paleontology, and archaeology. - You can use it to talk about how scientists study the Earth’s history or the timeline of life on Earth.
Example Sentence: - "Geological dating showed that the fossils were over 100 million years old."
Advanced Usage: - In advanced discussions, geological dating can refer to various techniques, such as radiometric dating (which uses the decay of radioactive isotopes) or stratigraphic dating (which looks at the layers of rocks).
