Intro to Radioactive Dating 🚀
- Radioactive dating (or radiometric dating) is like the ultimate stopwatch for scientists. 🕰️
- It uses changes in radioactivity to figure out how old stuff like rocks and fossils are.
Carbon Dating - Nature's Calendar 🌲
- Used mostly for things up to about 60,000 years old (so, no dinosaurs! 🦖).
- Here's how it works
- Plants and animals munch on carbon throughout their lives.
- When they die, it's like their carbon clock stops ticking.
- There's stable carbon (carbon-12) and the more drama-filled, unstable carbon-14.
- Over time, carbon-14 says "goodbye" and turns into nitrogen-14. Bye, buddy! 👋
- Carbon-14 has a half-life of 5700 years. This means half of it will have transformed into nitrogen-14 after that time.
- By measuring the ratio of carbon-14 to carbon-12, we can tell how long it's been since Mr. Plant or Mrs. Dinosaur took their last carbon snack.
Rock's Age & Geology's Magic Tricks 🪨
- Rocks don't munch on carbon, but they've got their secrets too.
- Geologists can know their age by looking at the uranium inside them.
- Uranium-238 eventually turns into a lead isotope and takes 470 billion years for half of it to do so.
- Uranium-235? It's a bit faster. Half becomes a lead isotope in 700 million years.
- The cool bit: comparing the two gives a cross-check. Like double-checking your answers in a test!
