You can find many other articles on our website that discuss these issues.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
We can repeat our observations tomorrow, but we can’t go back to last week to repeat them.
The only way we know our observations were the same last week as they are today is if we have an eyewitness testimony from someone who made the same observations last week.
To begin with, is the earth approximately 4 billion years old?
Actually, the latest estimates suggest a date of 4.57 billion years.
Read the passage in this science printable to learn about the history of radioactive dating and its uses.
Students will answer comprehension questions and solve word problems using a table with information about the half-lives of radioactive elements.
For example, it has to be assumed that all the daughter isotopes found in rocks today have been derived by radioactive decay of the parent isotopes.
It also has to be assumed that the rate of decay of the parent isotopes in the past has occurred constantly at the same rates measured today.
In the Bible, we have the eyewitness testimony of someone who has been present throughout all of history and who has told us what happened.
