Document Summary

Sedimentary rocks are rocks formed by the accumulation of sediments: developed principles of stratigraphy (the study of geological strata): Fossils of similar organisms are found in widely separated places on earth. Certain fossils are always found in younger strata while others are always found in older strata. Half-life is the time interval it takes for half of the atoms in a radioisotope decay to become a different, stable/nonradioactive isotope (radiometric dating) Need to know the concentration of the isotope at the time of the e(cid:448)e(cid:374)t a(cid:374)d the radioisotope"s half life: use c-14 and c-12 to date fossils no older than 60,000 years. H, a, and pro are the precambrian period and lasted 3. 8 bill years.
