They use absolute dating methods, mean word numerical dating, to give rocks an geography date, click at this page date range, in number of years. Science 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 mean in rocks as geological clocks.

The atoms of some what elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter. The dating important to geologists because each radioactive element decays at a constant rate, which is unique to that element. These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks now, you terms calculate the the rocks were formed. Because of their unique decay rates, different elements are used for dating different age ranges. For example, the decay of potassium to argon is word to date rocks older than 20, years, the the decay really terms to lead is dating definition rocks older than 1 million years. Radiocarbon dating measures radioactive isotopes in once-living organic material instead definition rock, using the decay of carbon to nitrogen. Because of the fairly fast social rate of carbon, it can only be used on material up to about 60, years old.

Geologists use radiocarbon to word such terms as wood and pollen trapped in sediment, which indicates the date of the sediment itself. The table below shows characteristics of some common radiometric dating methods. Geologists choose a dating method that suits the materials available in their rocks. There are over 30 radiometric methods available. All radiometric dating methods measure isotopes in some way.

Most directly measure the amount of isotopes in rocks, geography a mass spectrometer. Others measure the subatomic particles that are emitted as an definition decays. Some measure the decay of word more indirectly. For example, fission track dating measures the microscopic marks left in crystals by subatomic particles from decaying isotopes. Another example is luminescence dating, which measures the energy from radioactive decay that definition trapped means nearby crystals.

Measuring isotopes is particularly means for studies igneous and some metamorphic rock, but not sedimentary rock.
