- What are resin fossils and why are they important?
- A fossil was found that contained 20% of the parent element + 80% of the daughter element. It was determined that the fossil was about 28500 years old. What is most likely the parent element? What is the daughter element?
- What does the presence of dinosaur footprints in an area where no dinosaur bones were found suggest?
- What would happen if you added elements to fossils or whatever you are dating?
- How can fossils provide evidence for evolution?
- What do scientists learn about fossils by using carbon-14?
- How was the half life of carbon 14 determined?
- The half-life of carbon-14 is 5600 years. If charred logs from an old log cabin show only 71% of the carbon-14 expected in living matter, when did the cabin burn down?
