For the half of the radioisotopes of a certain kind to decay into more stable isotope, the amount of time required is called The Half Life.
Radiocarbon dating is typically used to date more recent objects like bones, cloth, wood, and plant fibers.
Sedimentary rocks cannot be accurately dated using isotope dating because this Rock type is formed through the sedimentation of different rocks and minerals fragment.
Using the principle of faunal succession, scientist can determine the age of rocks by the fossil flora and fauna embedded within them.
Explanation:
