• It is estimated that the earth formed four to six million years ago.
• The study of rocks and the fossils embedded in them that has provided the most important clues to the early beginnings of the Earth.
• Radiometric dating allows scientists to determine the ages of rock strata in thousands or millions of years before the present.
• Radiometric dating involves the calculation of when the decay process began based on certain radioactive isotopes.
• Certain examples of isotopes are potassium-40. It's a radioactive isotope. An example of a stable isotope is argon-40. Another radioactive isotope is carbon-14.
