Explain how radioactive decay is used in carbon dating
Radioactive dating of rock samples determines the age of rocks from the time it was formed.Geologist determine the age of rocks using radioactive dating.
Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.Rutherford and Soddy (1902) discovered that the rate of decay of a radioactive isotope depends on the amount of the parent isotope remaining. Any technique which dates a material based on the known decay rate of a radioactive component of the material is a form of radiometric dating.There are many radioactive elements and thus many applications of the basic principle.carbon dating) to as long as billions of years (e.g. The evidence is mainly from radioactive decay - measuring the ratio of different elements and isotopes.
Do some reading on "radioactive dating" or "radiometric dating" for more details - for example, in the Wikipedia.Radioactive decay is not the same as radioactive dating, but you need the decay to get the date.
