Different types of fossil dating
The starting isotope is called the parent and the end-product is called the daughter.
The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.
The method of calculating radiometric dates is like using an hourglass.
You can use the hourglass to tell time if you know several things: the amount of sand in the top of the hourglass when it started flowing, the rate that the sand flows through the hole in the middle, and that the quantity of sand in each chamber has not been tampered with.
Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.
Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.
If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.
For example, if you began with 1 gram of carbon-14, after 5,730 years you would be left with 0.50 g and only 0.25 g after 11,460 years.
Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it.
Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
The Bible gives a much different picture and explains that relying on man’s reasoning is foolishness.
However, there are many methods that can be used to determine the age of the earth or other objects.
The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.
