Geologists use radioactive dating to...
- determine the relative age of rock layers.
- tell the difference between molds and casts.
- tell where one soil horizon begins and the next one ends.
- determine the absolute ages of rocks.
I think it is to determine the absolute ages of rocks, but I'm not quite sure. If someone could explain the correct answer in simple enough terms for a thirteen year old to understand I'd be much obliged. The only explanations I've found so far are too hard to understand.
