I really don't see anything wrong with this.. How do scientists use radioisotopes to determine absolute dates for rocks? Would you like to merge this question into it? Would you like to make it the primary and merge this question into it?There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils. The most common is U U is found in many igneous rocks, soil and sediment. U decays to Pb with a half-life of million years. Radioisotopes are used by scientists to date rocks in a method called radiometric dating. The isotopes of an element are the atoms that have the same number of protons and electrons but different numbers of neutrons. When atoms of a radioactive isotope are included in the formation of a crystal, that crystal becomes the parent isotope.

Many rocks and organisms contain radioactive isotopes, such as U and C These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay.

It is captivating and compelling…covers all the bases. Evolution is completely at odds with the Second Law of Thermodynamics and Law of Biogenesis—and it has never been observed within living populations or proven by empirical science. Nevertheless, paleontologists Paleontologists study prehistoric life forms on earth by examining plant and animal fossils. Such fossil assemblages are known as index fossils which have been specifically chosen by paleontologists to represent a particular sedimentary rock layer. Based on the rule of superposition Superposition assumes the youngest rock layer is on the top and the oldest is on the bottom—but in reality, this is not the case throughout much of the world.
