Intro to Geology
Half-life is the time required for half of the radioactive nuclei in a sample to decay into a different element or isotope. This concept is crucial in understanding radioactive decay, which is a key process in absolute dating methods used to determine the age of rocks and fossils. By measuring the remaining amount of a radioactive isotope and knowing its half-life, scientists can estimate how long it has been since the material was formed.
congrats on reading the definition of half-life. now let's actually learn it.
