How are Relative Dating and Absolute Dating similar?

Dating Rocks and Fossils Using Geologic Methods

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes.

Absolute dating also known as radiometric dating is based by the measurement of the content of specific radioactive isotopes of which the "half time" is known. Half time is the time needed for half of a given quantity of an isotope to decay in its byproducts. Comparing the quantity of the parent form and the byproduct will give a numerical value for the age of the material containing such isotopes. Example include carbonnitrogen, uranium-led, uranium-thorium. Relative dating instead allows for identifying the sequential order of geological events one relative to the other.
