What is the use of radiometric dating
Also, because Earth formed as part of our sun’s family of planets – our solar system – scientists use radiometric dating to determine the ages of extraterrestrial objects, such as meteorites.These are space rocks that once orbited our sun, but later entered Earth’s atmosphere and struck our world’s surface.But Earth’s layers of rock did not give up the secret of Earth’s age easily. However, from working with layer upon layer of rock laid down on Earth over long time spans, early 20th century scientists came to believe Earth not of atoms of one chemical element into another.
Over the decades of the 20th century, scientists documented tens of thousands of radiometric age measurements.
When it comes to determining the age of stuff scientists dig out of the ground, whether fossil or artifact, “there are good dates and bad dates and ugly dates,” says paleoanthropologist John Shea of Stony Brook University.
The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.
In the early part of the 20th century, scientists still weren’t sure how old Earth is.
Nowadays, scientists use radiometric dating of various sorts of rock – both earthly and extraterrestrial – to pinpoint Earth’s age.
