Answer the questions about each aspect of radiometric dating as you move through the various exercises of the Radiometric Dating Lab.
By looking at layers of rocks, scientists can tell which layers are older or newer than others; however, they can not tell exactly how old these layers are.
Technology has progressed phenomenally since Steno's time.
But what's interesting is that a small fraction of carbon-14 forms, and then this carbon-14 can then also combine with oxygen to form carbon dioxide.
And carbon-14 is constantly doing this decay thing. So over the course of 5,730 years, roughly half of them will have decayed. Well, if you know that all living things have a certain proportion of carbon-14 in their tissue, as kind of part of what makes them up, and then if you were to find some bone-- let's just say find some bone right here that you dig it up on some type of archaeology dig.
Now that you have discovered the method that scientists originally used to date geological features, you may be questioning the accuracy of this dating method.
