Dating fossils and artifacts 7 and above dating
Several different methods fall under the umbrella of radiometric dating, but here is the basic concept: Certain unstable isotopes of trace radioactive elements in both organic and inorganic materials decay into stable isotopes. By measuring the proportion of different isotopes present, researchers can figure out how old the material is. The original element is called the “parent” element and the resulting element is called the “daughter element.” To find the age of a particular item on which this method can be used, scientists first measure the amount of parent and daughter elements it contains, then apply the applicable rate of decay.
Entering this (and other) information into a formula results in the age of the item. When you were introduced to algebra, you realized horrifically that a math problem could contain letters. In order to find the value of a, the number it is multiplied by (2) and another number that is added (3) are given, as well as the number they will be equal to (7) when the order of operations is followed.
In order to solve for the correct age of the rock or fossil, the scientist must “plug in” certain constants that are known to be true. Radiometric dating techniques depend on three unreasonable assumptions (outlined in this Apologetics Press article)- the equivalent of constants. Upon realizing that I had been a victim of the widely held belief that mainstream science is “unbiased” and the erroneous beliefs that follow, I embarked on a crusade to share the overwhelming evidence revealing science's lesser known yet undeniable validation of the biblical creation account.
absolute dating methods, circular reasoning in scientific dating methods, guide fossils, how accurate are scientific dating methods, index fossils, is radiometric dating accurate, radioactive decay, radiometric dating, relative dating methods As a scientist, it is hard for me to fathom anyone who has scientific training and does not believe in God. from the University of Rochester in nuclear chemistry and a B.
The article goes on to explain that there are two categories of dating: relative and absolute.
Before scientists developed absolute methods of dating, relative dating methods were used.
Index fossils are defined as: Any animal or plant that is preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment.
A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
