What is the principle behind the method of radioactive:dating?
That certain isotopes of elements decay at a known rate over time
That fossils found in different sedimentary layers are of different ages
That new forms of life arise at different times in the history of Earth
That the physical characteristics of fossils can be used to determine their age
Solution
The principle behind the method of radioactive:dating is that certain isotopes of elements decay at a known rate over time, and by measuring the ratio of isotopes in a sample, scientists can determine how long it has been since the organism dieD)
