Question
What is radioactive dating based on?A.The kind of element the isotope decays toB.The half-life of the radioactive materialC.The age of the radioactive materialD.The type of radiation being emitted
Solution
Radioactive dating is based on B. The half-life of the radioactive material.
Here's a step-by-step explanation:
-
Radioactive dating, also known as radiometric dating, is a method used to determine the age of rocks and other materials.
-
It is based on the decay of radioactive isotopes present in the material. These isotopes are unstable and break down over time at a predictable rate.
-
The rate of decay is measured in terms of half-life, which is the time it takes for half of the radioactive isotopes in a sample to decay.
-
By measuring the ratio of the amount of the original radioactive isotope to the amount in the sample, and factoring in the known half-life, the age of the sample can be calculated.
-
Therefore, the half-life of the radioactive material is crucial in radioactive dating.
