Earth science q: how is radioactive dating used to determine the age of an object a: why are fossils only found in sedimentary rocks a: fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures.
Scientists have developed more than a dozen methods for determining the age of fossils, human artifacts, and the sediments in which such evidence is found. The science of studying fossils the type of excavation method used depends on the type of sediment the relative proportions of these isotopes within buried rocks can be used to establish when they were last exposed to the atmosphere. Geochronology: geochronology, field of scientific investigation concerned with determining the age and history of earth's rocks and rock assemblages such time determinations are made and the record of past geologic events is deciphered by studying the distribution and succession of rock.
