How do scientists use radiometric dating to determine the age of a rock

A Deeper Radiometric dating isn't the only method of determining the age of rocks. This makes carbon an ideal dating method to date the age of bones or the remains of an organism. This is what archaeologists use to determine the age of human-made artifacts. Determining the number of years that have elapsed since an event occurred or the specific time when that event occurred atomic mass: Coastal Hazards. The precision of a dating method depends in part on the half-life of the radioactive isotope involved.

Remanent magnetization in ancient rocks that records the orientation of the earth's magnetic field and can be used to determine the location of the magnetic poles and the latitude of the rocks at the time the rocks were formed.

Dating Rocks and Fossils Using Geologic Methods

With radiocarbon dating, we see that carbon decays to nitrogen and has a half-life of 5, years. Fossils, however, form in sedimentary rock -- sediment quickly covers a dinosaur's body, and the sediment and the bones gradually turn into rock. Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy. Geologists also use other methods - such as electron spin resonance and thermoluminescencewhich assess the effects of radioactivity on the accumulation of electrons in imperfections, or "traps," in the crystal structure of a mineral - to determine the age of the rocks or fossils. If a material that selectively rejects the daughter nuclide is heated, any daughter nuclides that have been accumulated over time will be lost through diffusionsetting the isotopic "clock" to zero.
