Using fossils as guides, they began to piece together a crude history of Earth, but it was an imperfect history.After all, the ever-changing Earth rarely left a complete geological record.Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.Segment from A Science Odyssey: "Origins."Geologists have calculated the age of Earth at 4.6 billion years.
Write a series of nuclear equations to represent the bombardment of Al-27 with a neutron to form a product that then undergoes an alpha decay followed by a beta decay.
Radiometric dating methods are used to establish the geological time scale.
All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
(Express your answers as a series of nuclear equations separated by commas.) THank You!!
his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.
