Showing their age dating the fossils and artifacts that mark the great human it is possible to measure the ratio of potassium-40 to argon-40 and estimate a. Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old this has caused many in the church to reevaluate the biblical creation.
The potassium-argon (k-ar) isotopic dating method is especially useful for determining the age of lavas developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale. Potassium-40 is another radioactive element naturally found in your body and has a half-life of 13 billion years other useful radioisotopes for radioactive dating include uranium -235 (half-life = 704 million years), uranium -238 (half-life = 45 billion years), thorium-232 (half-life = 14 billion years) and rubidium-87 (half-life = 49 billion years.
