Exponential Growth and Decay - Problem 7 637 views
Since we know the half-life time for many elements that naturally occur in nature, we can use exponential modeling to describe decay of organic material and make predictions about the age of fossils based on how much material is left. Here, we look at Carbon-14 to predict the age of a fossil. Keep in mind that for all half-lives, the ratio of amount after time to starting amount will be 1/2.
