RADIOMETRIC TIME SCALE

In the figure, that distinct age range for each fossil species is indicated by the grey arrows underlying the picture of each fossil. There are different methods of radiometric dating that will vary due to the type of material that is being dated. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. Carbon has three naturally occurring isotopeswith atoms of the same atomic number but different atomic weights. After 10 half-lives, there is a very small amount of radioactive carbon present in a sample. The atomic nucleus that decays is called the parent isotope.
