Determining the relative age of a rock layer is based on the assumption that dating methods to determine the ages of the surrounding rocks. It's this resetting process that gives us the ability to date rocks that This method relies on the uptake of a naturally occurring radioactive.
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is. Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand. Layers of rock build one atop.
