There are two types of radioactive dating, which are potassium-argon dating (potassium-40) and carbon-14 dating.
While Pottasium 40 is used to date ancient rocks because it has a long half-life. Carbon-14 on the other hand, is used to date plant and animals because they contain some form of carbon-14.
Hence, Radioactive dating can be compared to an hourglass, with the UNSTABLE elements on the top. Scientists compare PARENTS AND DAUGHTER ELEMENTS in the rock to determine its age. Potassium-argon dating is ideal for dating IGNEOUS and ANCIENTrock.
