Radiometric dating worksheet answers
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
However, to read any clock accurately we must know where the clock was set at the beginning.
For decades, the biologists have boldly proclaimed that, whereas we cannot observe today one type of creature evolving into a totally different type of creature, “Time is the hero of the plot. No one even bothers to ask what assumptions drive the conclusions.
So let’s take a closer look at these methods and see how reliable they really are.
In this case, the uranium is called the parent and the lead is called the daughter element. It is not affected by temperature, pressure, or other physical changes.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.The atoms in each chemical element may vary slightly in the numbers of neutrons within their nuclei.These slightly different atoms of the same chemical element are called isotopes of that element.
Most people today think that geologists have proven the earth and its rocks to be billions of years old by their use of the radioactive dating methods. Given so much time, the ‘impossible’ becomes possible, the possible probable, and the probable virtually certain.
