e ear is billions of years old. e most useful me ods for measuring e ages of geologic materials are e radiometric me ods- e ones at make use of radioactive parent isotopes and eir stable dhter products, as preserved in rocks, minerals, or o er geologic materials. e main condition for e me od is at e production rate of isotopes stays e same rough ages, i.e. 03, · ermal ionization mass spectrometer used in radiometric dating. Radiometric dating calculates an age in years for geologic materials by measuring e presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its . Since e half-life of Rb87 is 48.8 billion years, we can substitute in e half-life equation: 0.954 = (1/2) raised to e power (age/48.8), where age = age in billions of years. erefore: log.954) = (age/48.8)(log 1/2). is solves to age = 3.3 billion years.

Radiocarbon dating is possible because of e existence in nature of e radioactive isotope 14 C (albeit in small quantities. e vast majority of natural carbon is composed of e stable isotopes 13 C and 12 C). is isotope has e advantages for e study of e human past of a conveniently long half-life (of ∼5730 years, al ough by convention radiocarbon results are calculated on e. 13, · e key difference between relative dating and radiometric dating is at e dating cannot provide actual numerical dates whereas e radiometric dating can provide actual numerical dates.. Relative dating and radiometric dating are two types of parameters at we use to describe e age of geological features and to determine e relative order of past events. Age of e Ear – Uranium-lead Dating. e age of e Ear is about 4.54 billion years. is dating is based on evidence from radiometric age-dating of meteorite material and is consistent wi e radiometric ages of e oldest-known terrestrial and lunar samples.
