Igneous rocks
They are able to tell the order in which events occured, NOT how long ago they occured.Identify the order in whicih rock units formed(:rocks makes babys with apenis
Relative dating. (do your own study island)
False. The half life of Carbon 14, which is a radioactive isotope and unstable, is only 5,730 years. Carbon 14 dating techniques are only useful up to 60,000 years and therefore are mainly used by archaeologists and not very much by geologists.
== == The age of a sedimentary rock formation can be estimated by comparing it to radiometrically dated rock formations that contain the same fossil organisms. Geologic time categories have been identified according to the radiometric dating of fossils and the fact that they appear only in certain time periods. Therefore, if you look at a rock formation and find a trilobite fossil that has been identified by previous dating techniques as Cambrian, you can be fairly certain that the formation you are looking at is also Cambrian.

Sedimentary Rocks
would you use uranium-lead radiometric dating to finnd an igneous rocks age
their ages
No, radiometric dating can only be used on certain minerals that contain radioactive isotopes. These minerals include zircon, potassium feldspar, and biotite, among others. Not all minerals contain radioactive isotopes, so radiometric dating cannot be applied to all minerals.
Carbon Dating
Radiometric
radiometric
They can use either radiometric dating or magnetostratigraphy.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Carbon 14 dating is the best known example of radiometric dating, but there are many others. Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
It's called radiometric dating.
