It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
<h3>How are isotopes used in radioactive dating?</h3>
These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

light intensity or humidity. Under kinesis, the response to the stimulus activated
by an organism is non-directional.
Answer:
I think climate change can be either fake or real. I do believe temperatures are rising, but if you look at the history of the earth, it's gone through many ice ages and changes, so I would assume that it is no big deal. There is no evidence that temperatures are rising at a deadly rate, but weather has been unpredictable for a while now. Then again, these are my thoughts on climate change, so I'm not sure if I'm right or wrong. Hope I gave some useful information!
