Numerical absolute geologic age dating Cam4chat sex
It is difficult to assign an age to Earth by dating materials formed on Earth because Earth materials are constantly cycled by the tectonic forces and rock cycle.But meteorites are considered a closed system, and the Canyon Diablo meteorite is assumed to have not undergone any chemical changes since its ancient formation.

James Hutton is often called the father of modern geology.After the work of Hutton and Lyell, numerous scientists attempted to assign an age to Earth.Early attempts included estimates based on how long it would take for the oceans to become salty (about 100 million years) or how long it would take to accumulate the known thicknesses of fossil-bearing sedimentary rock layers (about 500 million years).An Irish Bishop named James Ussher, who lived from 1581 to 1656, compiled research from a literal reading of the Bible and concluded that Earth was a little over 6,000 years old.He based his assertion on chronologies, genealogies, and the biblical account of Earth's creation given in the first eleven chapters of Genesis, in which Earth is said to have been created by God in six days.
