Oct 04, · T he presupposition of long ages is an icon and foundational to the evolutionary model. Nearly every textbook and media journal teaches that the earth is billions of years old. Using radioactive dating, scientists have determined that the Earth is about billion years old, ancient enough for all species to have been formed through evolution.1 The earth is now regarded as between and Author: Mike Riddle.
Another important atomic clock used for dating purposes is based on the radioactive decay of the isotope carbon, which has a half-life of 5, years. Carbon is produced continuously in the Earth's upper atmosphere as a result of the bombardment of nitrogen by neutrons from cosmic rays.
Each radioactive element has a half-life, which tells how long it takes for half of the element to decay. For potassium 40, the half-life is about billion years. In general, in one half-life, half of the parent will have decayed. In two half-lives, half of the remainder will decay, meaning 3/4 in all will have decayed.
Radiometric dating relies on the constant rate of radioactive decay that occurs among unstable isotopes such as Uranium, Thorium, Potassium, and Carbon Scientists know that if the rate of decay follows a pattern, they can estimate the time when the decay started, or the “birth” of the isotope.
Since the half-life of 14 C is 5, years, it is a great element to use for dating objects that are between 1, and 25, years old. We use other radioactive elements to date older or younger objects or objects that are not made of organic material (such as rocks).
