Methods of Dating the Earth Part 2: Absolute Dating (Radiometric Dating)
Вставка
- Опубліковано 4 вер 2024
- We just learned about relative dating, but if you really want to calculate the age of a rock, absolute dating is what you need. This takes advantage of the presence of radioactive nuclides that decay at a reliable rate, so it is also called radiometric dating. How does this work? Let's learn about it!

Creationist: "I think it is best that we reject the existence of radiation, after all, radioactive radiation can't be see with the naked eye, therefore the earth is 6000 years old"
And gawd is visible...?😆

As a teen, I listened to creationist arguments that leaching in groundwater might alter the daughter and parent isotope ratios, Invalidating the method. And then I learned the technique can be used on meteorites in space, Not likely to find much groundwater exposure. That was a pivotal moment for me.
Although there is considerable evidence to suggest (though perhaps not yet prove) that much of the water on our planet came from meteorites, or other water-bearing matter that struck the Earth during its early formation. This same theory is one of several possible explanations for the water-ice we've discovered beneath the surface of the Moon's southern pole.
Also, we can cross test samples with different radiometric dating methods. There could be contamination in rare cases, but it's impossible that a sample would be cobtaminated with two or more different isotopes in the correct proportions to produce the same date.
@@valkeakirahvi Exactly right.
@@valkeakirahvi Yeah but, What if the devil put those isotopes in the ground Just to test your Faith?
@@greenpilgrimz3763 That is such a rude and patronizing thing to say to a complete stranger. Who are you to insert yourself and try to make this person nostalgic for an imaginary relationship? Get off your high horse and learn to mind your own piety.
Dating methods was one of my favorite subjects in my archaeology class! My favorite dating method might be tree rings, because it provides a highly precise form of relative dating which can transition into absolute dating if you can extend your tree ring atlas back that far.
I agree, it’s a great method for not only precision dating, but also climate changes during the lifetime of the trees. Unfortunately, wood is seldom preserved for a long time after the tree dies - exceptions include anaerobic bogs and swamps and arid desert environments - so the best we can do with it is a few tens of thousands years. There are older samples preserved in some Pleistocene glacial deposits, but dendrochronology depends on having a continuous series of at least partially overlapping samples, so there are gaps once you get that old.
.. and is also good to tell the local climate for every year!
Looks like James Tour has been exploring the Earth core because i saw a headline " James Tour has hit rock Bottom". what an achievement.
For some reason, I keep imagining professor Dave teaching us pickup lines to ask out the earth

The best methods to dating the Earth is as follows: 1) buy her flowers, 2) while you may celebrate Mother's Day and Earth Day, it should be celebrated every day, and 3) most important of all, always respect her for she gives you everything 🥰

thank you for all the work you put into your channel! been watching since you got me through chem 1 in high school and now i'm about to graduate college with a degree in environmental sciences :)
Ah, I should have guessed there were more than just Uranium radiometric dating.
Also, these "Dating the earth" jokes aren't hitting folks. Y'all can stop.
Thank you!
Just thumb down the twits.
thank you so much for this, this is part of one of my uni modules and you explained it so much better than the lecturer
Will you please make videos covering topics of paleontology ? 🙏
My favorite method for dating the Earth is asking what the Earth is into. Really trying to get to know not only the terra firms portion, but the entirety of the oblate spheroid, because Mother Earth got hips. Dating the Earth doesn't have to be complicated, just be interested in the Earth herself and her interests. Find out what's really inside of her, you know, mostly iron at 5200 Celsius that is about 1200 kilometers or 750ish miles if you are from Freedom-land. Find out about her interests, like not extracting parts of her body and setting them on fire to choke her. Find your common interests, like I enjoy walks on the beach and she has literally infinite beaches because of the coastline paradox.
Once you two start taking about the fractal curve-like properties of her coastlines naturally and unforced, you know it may be time to move to the next level of your relationship and not just date the Earth, but consider a serious commitment. Earth is looking for something long term, like around 7.5 billion years, so make sure to be upfront about what you are looking for at the beginning when you start dating the Earth so neither one of you gets needlessly hurt.
I hope this helps when dating the Earth. I try to avoid radiometric dating, at least in the beginning because asking a planet about their radioactive elements and their decay products just isn't appropriate until the 3rd date at the absolute earliest.
As friendly advice I'd not recommend trying to date Venus or Saturn. Venus has a fiery temper and can be a real hot-head, while Saturn may say she is separated and looking to start something new, but she is still wearing her wedding ring. Plus Saturn is always surrounded by a ton or orbiters, which can be a massive red flag.
The earth is 4.567 billion years old.

Appreciate you, these videos are so good. I’m learning so much.
Thank you Professor Dave, even if I know this content, I don't mind listening to you talk. You're smart.... Very smart, and I dig it!❤
I always go to professor Dave for dating advice
Sir I watched your entire mathematics series
Please also make statistics 📈series for student

Why does the presence of hot fluids like magma influence the presence of parent/daughter isotopes in a rock sample? Does the mineral composition homogenize with the magma when it gets too hot?
Explained crystal clearly.
But, please increase the frequency of lectures
Bud, I post three tutorials per week. I'm killing myself over here. Nobody who runs this type of channel by themselves posts as often as I do.
We love your work, can’t help being greedy and wanting more.
Have you tried learning faster?
Ive been waiting on this video. Thank you dave.
this guy knows a lot about the science stuff
He in fact does my good sir
Hey Dave, you said that the best rocks to date are igneous rocks, but how would you pass around the barrier caused by excess Ar isotope in igneous rocks?
I was also wondering this
There are a number of alternative isotopic elements that could be used as well perhaps?
What are the some of the assumptions we need to make to ensure that we are correct that uranium decays completely into lead within Zircon?
I remember when one of the honest creationist....😅 I cant type that with a straight face. Matt Powell saying rocks from Mt Etna or St Helens were dated with their Geochronology lab and then shows an image of some amateur radio operators bench that had an oscilloscope and an Icom 7300 on a rack, where you guessed it a Geochron map im the background that we use to see where rhe grayline propagation will be as well as other ham radio ooerating details we sometimes use. I couldnt help but stop at Dr Peels channel to point that out to them on their dishonesty.
There is no such thing as an "honest creationist".
Ah dang for a sec I thought Dave was going to take a scientific approach to dating
Have you tried just inviting the Earth to a nice dinner and a movie?
Hey professor, as someone who is bad at listening to english, i have to say youre old videos helped me alot better because you pronounced things slower but now i find it a little hard because you speak more normally :(
Can you go back to how it was before, thank you so much, im sorry english is not my first language
or you could just go to settings & change the speed to slower
Why dont you just change the playback speed of the video?
@@weschilton that just makes it bad
@@tahaymvids1631 This might not be the best solution, but...
I recently had incredible success learning new languages using the free web-based service "Duolingo".
Perhaps it could also be used to achieve comprehension despite talking speed?
Good luck!
So I have a question ❓ so if I were a Egyptian priest during Ramsey reign how would I state the date or age or cycle. Like I was born in 1950 how did they communicate that thought.we are the ones that call it bc ad not them. And I am 100 percent positive our dating is wrong.who magical started the calendar and disregard other cultures. Say the Egyptian themselves Chinese Indian culture.
I came in here to make a relationship joke, but i already know theres enough of that here
Simply reason that young earth creationists are wrong
Surprised not many creationists here after the debate
Many they don’t want to learn anything against their faith
We have enough issues with the stupid comments about taking the earth out to dinner. Please no creationists!!!!
I knew a tiny amount about this, thanks to the radon mitigation system in my basement.
All the different ways to date the age of the earth and all creationist know is carbon, and I've had one say you wasn't there so can't show decay rates were the same
And... none of them met Adam or Eve or Noah either.
The "you weren't there" play is self defeating and I'm boggled that anyone is swayed by it
@@alexmcd378 They know they're losing the debate and relevance in the Information Age, so the argument that "you had to be there / you had to personally witness it" is designed only to draw a false equivalence. They want science to be demoted to, at best, equally faith-based as any religion or, at worst, merely a guess or opinion. In fact, it's not designed to persuade the one they're arguing with; it's designed to protect the one making the argument and any other theist watching the debate. It's just a way to reinforce the meta-idea that their faith is actually logic-based when they only know what their priest and guest pastors tells them.
Another great video, thanks!
the young earth Creationists are boiling with rage about this
Beautiful
I understand that isotopes decay at the same rate no matter where they are, however are there ANY extreme contusions we can create in a lab that causes these to decay at another rate. Example: absolute zero, or vacuum state? Thanks.
No
No, the decay process is unique to the internal instability of the atom itself, its essentially a statistical mechanism. Due to the differences in strength between the strong and weak nuclear forces and electromagnetism, and what ever the ratio of nucleons is in the atom. Think of it like the three body problem, the three bodies will be in motion with each-other, but there are points where if they reach a certain configuration, one of the bodies can be ejected. In sufficiently massive unstable particles they emit nuclides (which is what isotopes are a sub category of) and they can be all sorts of funky shit that can have the same neutron number but a different mass, or the same mass and a different ratio of protons to neutrons.
So its based on the inherent instability inside an atom because of the ratio between protons and neutrons. The only thing it can depend on is the state of the matter decaying, because certain forms of electron emission may not work the same if solid vs liquid.
Is it bad that I read (Radiometric Dating) as (Romantic Dating)
I like my Earths a little older. More experienced.
thank yoiu
Ratio of lead to uranium worldwide?
A box of chocolates and a bunch of flowers goes a long way 😂
Saw a prof dave video come up with a thumb nail off a globe and thought you'd done another flat earth debunk!!
Oh neat! I always wanted date earth-chan!.
Ow.... THAT kind of dating....
When I clicked on this video I thought we were gonna talk about a different type of dating.
I read somewhere that "negatron decay" was also the phenomenon of Transformers slowly disappearing. ;-) j/k of course.
Thanks for the eloquent tutorial on "how to demonstrate that creationism is a load of crap."
I can't even get 1 girl and this man is out here dating the entire earth I QUIT
Dating the earth? I barely know her
thank you, now I know how to take my habitable planet out to a nice dinner!
But what do u do if u see a Spaceman!???????.......…...park there man!!!....😂
I'm sure thee comments will be filled with knowledgeable creationists discussing the math and graph shown. /s
😂😂🤔
So far it’s mostly filled with jokes about taking the planet out to dinner.
@@mjjoe76 that is because the young earthers are still outside digging a small hole and raping it
Just here for the cocoa puffs comments from theists
I always dream of going on a dinner date with Earth ❤️
I read: how to date the earth and thought you went crazy
How do they know what the original ratio of isotopes was billions of years ago when the material was "formed?"
It's explained quite clearly in the video.
@@ProfessorDaveExplains but im a retard
@@thesunman At least you're a self-aware one.
I am so stupid. I thought this was a dating guide to get with the Earth.
One thing is missing: How do you check the absolute dates with another method? (The same method on different elements is insufficient.)
Different radiometric "clocks"
Plus other methods
@@rickkwitkoski1976 Such as? Carbon can be tested with dendrochronology (sp?), what about the other ones?
Isochron dating. Different isotopes of the same element in the same sample allows you to validate the method. They decay on a slightly different scale so you can check their relative amounts and rule out any problems there.
@@davidbutler1857 That would be the same method, wouldn't it?
Radioactive elements decay only one way, so you don't need another one. You can use statistical analysis to rule out issues with a 'single test' by just doing multiple tests with different labs, different people, etc. @@korbendallas5318

“Period of time” is not an acceptable phrase. It’s either “period” or “time”, not both.
It's grammatically and logically correct.
@@tadferd4340 It can also be a cycle, like orbital period or a dot at the end of a sentence. But we're talking about a defined amount of ongoing time Let's stay clear...
If the earth was flat, why can't I hear radio stations from all over the world...because there wouldn't be anything to attenuate their signals...?
Is the earth even single?
For the seemingly large amount of time and effort you put into these videos, you'd do extremely well to change your intro to something that doesn't feel disgusting to share and that doesn't reek of amateurism.
