What is radioactive dating wikianswers

measurement, measuring, mensuration, measure - the act or process of assigning numbers to phenomena according to a rule; "the measurements were carefully done"; "his mental measurings proved remarkably accurate" techniques to precisely measure the age of the eruptions of the Kalkarindji volcanic province where lavas covered an area of more than 2 million square kilometers in the Northern Territory and Western Australia.Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.The unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes.

But it wasn't until the late 1700s -- when Scottish geologist James Hutton, who observed sediments building up on the landscape, set out to show that rocks were time clocks -- that serious scientific interest in geological age began.So, we rely on radiometric dating to calculate their ages.Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.— David Gross at 23rd Solvay Conference in December 2005 Radioactive dating is a key concept in determining the age of the earth.
