Carbon dating only works for fossils that are less than 60,000 years old, so carbon dating won't work if you find a dinosaur bone because dinosaurs lived on Earth millions of years ago.Carbon dating is a way of telling the age of a once living thing by measuring the amount of carbon inside of it.You can test out of the first two years of college and save thousands off your degree.Anyone can earn credit-by-exam regardless of age or education level.While on a hike, a couple from Germany found what is now referred to as the Iceman.You might be wondering how we know that the Iceman is more than 5,000 years old. Carbon dating is a way of telling the age of a once living thing by measuring the amount of carbon inside of it.Relative age dating also means paying attention to crosscutting relationships.Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.
After all, a dinosaur wouldn’t be caught dead next to a trilobite.
Pretty obvious that the dike came after the rocks it cuts through, right?
With absolute age dating, you get a real age in actual years.
Unlike people, you can’t really guess the age of a rock from looking at it.
Yet, you’ve heard the news: Earth is 4.6 billion years old. That corn cob found in an ancient Native American fire pit is 1,000 years old. Geologic age dating—assigning an age to materials—is an entire discipline of its own.
