Why do you accept the many comments like "Hello, from India 🇮🇳" do you enjoy this sort of gross patronizing sexual attention?
And is this your career now? Not geology career, just a girl on youtube sponsored by "Brilliant"?
@@RobertCraft-re5sf Actually, I am a geology professor and researcher in addition to being a UA-cam science communicator :)
@@GEOGIRLmany thanks professor. Keep it up, please!
This is why I had to take 2 semesters of physics and 4 semesters of chemistry to get my biology degree. I also took a historical geology course, so I could understand evolution better.
Through much YouTubing, I have developed a keen sense for great communicators - and have become intolerant of presenters who clearly have not honed their craft. With this experience, and clearly subjective judgement, I believe you, Rachel, are one of the best educational communicators I have ever listened to. Thank you for your excellent & professional content, and through you, I have learned more about Earth and its history than I knew I wanted to know. I never miss a post, and look forward to each one. I hope you continue being a professional educator.
I SUPER admire her work with the slides. Having sat through so many bad presentations - and also having taught people how to use PowerPoint back in the 90s - it's truly awesome to see someone use the slideshow format RIGHT!
Wow, this comment is incredibly kind, thank you so much! These are the comments that really motivate me to keep posting😊
Happy New Year Rachel, thank you for every video in 23. You are brilliant at sharing your knowledge. You deserve every bit of success that I know is coming your way in 24 and beyond.
We’re so lucky to have you taking your valuable time to explain this stuff to us. Thank you!!!
Everything is connected to everything else. Difficult to study one discipline without bumping into others. Makes one appreciate anew the so-called Renaissance Man of centuries ago and the polymaths of today. Happy New Year to Geo Girl from an admirer!
As humans learn more the academic disciplines expand, further causing the inevitably of even the most brilliant of people of only being a jack of all trades, or an ace of only one.
Human knowledge is far more voluminous now then back in the day, and it will only keep increasing 🤔 well, unless a certain section of society takes full power
Yessss, my favorite subject lately! 😁
Thank God for young people like you. You encourage old guys like me that we are in good hands with new generations coming up.
How long it took us humans to find out how this all works and how old everything is! *Thank you for this lecture, Dr Rachel GeoGirl 🔬🔭🔨 and happy New Year! 🚀*
Thank you so much! And Happy New Year to you too!! ;D
@@GEOGIRLDo you get to pick a new name with the PhD? I feel "Doc Rock" would be cool! Not sure.
I'm an engineer (retired), but also took several geology classes for general interest and have always been fascinated by the latest developments in the Earth sciences. I really enjoy your videos. Who would have thunk releasing many millions of years of stored carbon in just a couple hundred years would be a problem? The Earth's geochemistry cycles are not to be trifled with because even if we try to geo-engineer our way out of past transgressions there could still be unintended consequences.
So much easier to correct course here than look for other planets, or terraform Mars, or many of the other hair-brained idiocy that Musk and friends keep putting out there.
Great overview of biogeochem. I was surprised to see the vid drop during the holidays too. Thank you Doctor Rachel 😁(I had too) and Happy New Year!
Another outstanding video from Rachel, who makes the best science videos I’ve ever seen on UA-cam. Thanks again for your fantastic work.
A new video from Geo Girl makes for a Happy New Year indeed!
Thanks for sharing and a Happy New Year to you. 😁
OMG WELCOME BACK! Lets go! New exciting video!
A question that has intrigued me for a while. How much of the water on Earth today is the original water that was included when our planet formed.? When plants and algae photosynthesize, they split water molecules, keep the hydrogen and excrete the oxygen. Then, when organisms metabolize, they take in oxygen and combine it with the hydrogen in their food to make new water molecules. So, what percentage of the water molecules that exist on Earth today are the same ones that existed before life appeared on our planet?
I started to watch this channel because I love Geology. I continue to watch because I love Geo Girl ❤
Rachel 🌸,
Thank you for the video 🎥. I was getting bored 😘on the elliptical🤸 without you.
Thanks for the video. It's important and kind of fun to think about things on a planetary geochemical scale.
If you wanted to recreate Oxidation Event conditions right now, what would you do? Would you use azolla? algae? What sort of large geological formations would you use? Could you separate the CO2 removal from O2 addition to the atmosphere? e.g. apply historical biogeochemical event learnings to current biogeochemical conditions.
Awesome video as usual!
I love your energy!
As you correctly stated, soil is not simply a product of physical weathering, but of life. Without life it would only be composed of small broken rocks called regolith.
In order to have soil, you need the chemical weathering promoted by life
Fun channel. I'm a EE/math guy, but these topics are quite interesting - takes me back to when I was a kid interested in minerals and the like. Thanks. Subscribed. Cheers ...
Earth science has always been a favorite of mine, and this channel has clear explanations and big-picture discussion that make it a favorite channel for learning more about all aspects of life and Earth.
Since i recently discovered yoir videos I have asked a couple of questions, but they were all getting around to exploring this connection. Finding the missing link between life and the environment is definitely the ultimate treasure. I guess a big part of understanding biogeochemistry would be understanding the formation of nerves in the embryo.
Lovely. I admire your ease of speech without a script (it doesn't seem like you use one)
I'm sorry that I can't remember, but have you ever done a video discussing soils, the farther and farther you go North into Canada, Alaska, and Greenland? I'm sure that you can find areas in Greenland devoid of any soil.
Thanks, enjoyed your video Professor (?) Rachel. In my past career in fossil fuel exploration I regarded the organic matter as an energy battery of sun energy millions of years old, which we are releasing geologically instantaneous. That definitely has an environmental impact.
I have shifted my focus on soil biogeochemistry. Earthworms are great little helpers.
I have at times wondered if the P in CHONPS is phosphate or potassium, but remembering potash as a source remains me.
As a visitor engagement volunteer at Scotland’s leading zoo I have developed an absolute fascination in biodiversity, ecosystems and ecovalues so more than appreciate the interconnectedness of our planets systems. The world around is an incredibly diverse and awesome place, with very finely balanced systems!
I love learning how natural systems and knowledge are all connected. Do you think that there's a trend towards greater specialization and pigeonholing in science fields? Whereas in older periods, the wisest people endeavored to advance in many diverse disciples. If you think the specialization trend is real, what effects do you think it has?
Those lucky U. of South Carolina undergrads get to learn from you in person starting next week! Enjoy yourself and good luck with your research, keep us all learning & growing ❤😊
Rachel: Welcome back! That was an absolutely wonderful discussion of the fusion of geochemistry and the biological sciences. I loved it and you presented beautifully. I look forward to more subjects on this topic.
Also…. So glad you are perusing your post doc at the University of South Carolina. I became familiar with the geology department years ago when taking courses by the legendary USC coastal geomorphologist Miles Hayes and his geochemist wife Jacqui Michel. Flew and studied the coastline of North and South Carolina, the Copper River delta of Alaska and the Aleutian Peninsula (where we crashed a plane on a beach) with Miles and Jacqui. We were observing modern depositional systems in search of analogs to ancient Alaskan stratigraphy. An amazing experience from an extraordinary professor and researcher.
Best wishes to you Rachel for your new home and research projects. South Carolina is a beautiful state with amazing geology (and fantastic golf courses..another of my passions since age 6!). Enjoy it all. Also looking forward to all your forthcoming GeoGirl postings…something I greatly look forward to every week.
I love this channel! Geo-girl is totally awesome! ❤😢😊
Was this your best year on UA-cam?
Thanks for the good work; love the shelves.
Happy New Year
It's all starting to come together!
Good to see you have survived Christmas and new year :-)
On a long enough timescale everything is a fluid. Life could be a simple equation of CHNOPS in a package labeled 'just add heat'. Very Informative video.
Unusually fascinating this time around. A sheer scale so expanded that it covers literally a whole planet. Geology-based studies extend tentacles in any directions. An excellent presentation, very satisfying to watch. I'd be more comfortable sitting on the side of viewer. Rocks or minerals are obviously inorganic, but this footage shows an intrinsically intertwined relationship with organic matters. A very convincing narrative of our mother earth, here it is! Extraterrestrial objects, meteorites, included (somewhere else). So, what about 5th element? Tell us all about it!
Great video. Thanks so much!
Excellent video. If you 'do requests' I would love to see a video about what sorts of ores and minerals would not be found on Earth if Earth did not have life. (Similarly, what sorts of ores would intrepid Martian miners not find because Mars (seemingly) has no native life?) (Also, since I'm babbling away here, what sorts of interesting ores would we find on Venus if we were to build a sunshade and cool it down to mineable temperatures?) In short - how important is life to the existence of our mineral resources?
Your explanations are very well done!
Great video! Thank you! I really like the rock collection in the background. Are those yours or are you recording while home for the holidays? Happy New Year! 🎆🎊
I remember Miche Thaller saying that she thinks of herself as a mobile rock, pointing out the similarities between geology and chemistry. LUCA (and its extinct forebears) were probably very similar to its surrounding complex organic chemicals from which it probably emerged.
I love learning about ologies! Happy New Year🎉
Great info explained well. Thanks Geo Girl.
Another great video. Thank you!👍
I enjoyed your educational video. Science is reality as compared to fiction as in religions. Happy New Year to everyone.
You hit the climate nail right on its head; at this point we need to solve the problems, not blame others for screwing up the planet.
Or look for another planet... I mean, wow.
For your next video, you can discuss bio geo chemo astronomy, just to show you can. Merry Christmas, Happy New Year, Seasons Greetings!

Great video! I just want to point out that the word "fossil" in "fossil fuels" is derived from the Latin fossilis, which means unearthed. Sinclair Oil Corporation's trademark and marketing is where most people think "oil comes from brontosaurus bones!" comes from. Although, A video about the abiogenic origin of oil would be awesome, but what do I know!? I'm just a UA-cam comment-
-As I sit pondering the hydrocarbon cycles hidden within Saturn's moon Titan☺
I’ve been studying the geological aspects of the Anthropocene, aka whether or not it should be its own epoch, and if so, where would be the golden spike, and why. The Anthropocene was originally named by “earth systems scientists.” Are you familiar with Earth Systems Science? It seems like it’s the same as what you described as “biogeochemistry.” I love the subject and I love your videos. Thank you.
Great video. Such an under-researched field
Happy New Year 🎊
Happy New Year! Every time I watch one of your videos I leave with 3 more to watch later haha :)
I want a rock display like yours. Thanks for the clear and informative lecture.
Great video, well done!
Looking forward to the P and S cycles because we hardly see them
Thank you. Nice work. It would be nice if a lot more people grew a familiarity with cyclical events in our world. It might make it a a little easier for people to grasp climate change, or any other affect we have on our world. Such learning has helped me start to see other elements of human life in terms of cycles and effects. There seems to be something along those lines in what could be termed a "Civilization Cycle." They seem to go through stages of establishement, growth, collapse and abandonment. Within them there are various cycles such as business and economic cycles. The effects of various elements about them, such as culture, invention and its effects, such as information distribution, will influence how they grow and spread influence. Something not taken into account seems to be the phsychology of resource accumulation, which tends to have a great deal of influence over the system's development. Resource accumulation combined with institutionalization, and industrialization has made our species particularly dangerous to a finite world because it overwhelms the natural cycles that would otherwise sustain life. This is why I suspect a major extinction event may be coming our way. It could be through the damaging effects of pollution, or climate change. It could also potentially be through reduction in diversity of biomass as our species tends to pressure the planet toward specific biomass preferences that serve our species. Such things as monoculture would make us extremely vulnerable to disease. Just some spitball thoughts.
Engagement. Boost. Algorithms. 💐
Student: "I thought this class was introduction to *astronomy*. Why are we seeing physics, chemistry, geology, and biology?"
Uh huh. Kind of hard to separate them if you want to do a good job, right?
It's Gaia theory! One more topic for you to cover! But, I've thought of another one(I'm thinking this morning) - the Rare Earth Hypothesis!
I'm tempted to say the Fermi Paradox as well! I consider the Rare Earth Hypothesis as the solution to the Fermi Paradox(and global nuclear war)
The Rare Earth Hypothesis was made famous by Ward and Brownlee; but, I grew up in the 80s finding Isaac Asimov's "Extraterrestrial Civilizations" on my father's bookshelves. I consider it the original Rare Earth Hypothesis book that nobody knows about. It's still not referenced in the Rare Earth Wiki!
I forgot to mention another idea for a video! When the North American and South American plates connected, life from each mixed. I first saw this while watching some Rare Earth Hypothesis youtube this morning!
Looking into PhD courses in Biogeoscience or biogeochemistry. Want to look at metallophytes. Plants that absorb metals from rock ores and their applications into the restoration of mines and possibly phytomining. Any advice?
thank you!
Very nice video. As an alternative to the slow process of planting more trees, is there a way to encourage the spread or activity of the bacteria that reduces co2?
if only iodine was also biogeochemically important... then we could have CHOPINS cycle, which would provide excellent classical music accompaniment.
Thanks a lot Dr Rachel Geo Girld. Also amazing the video about the biochemical cycles! One short question if you don't mind: why having more CO2 in the atmosphere like today, is not producing a huge blooming of the plants that breath it?...is it because plants need also other nutrients the availability of which has not encreased maybe? and and human-caused deforetation, etc...? Thanks!
So beavers make huge ponds that can be seen from space like the one in Alberta
How can one family of animals make such an impact?
Lol
Great Video and Thanks for all your work,
Happy New Year
Happy New Year, dear Geo Girl. .... Success!
Congratulations on your doctorate, I'm jealous since I still haven't gotten my associates. Still don't think it's thermodynamically possible to reverse climate change.
It's pretty cool indeed, but imo nothing beats paleoecology/paleobiogeography and natural history
Happy New year ✨💖🎉🥳🥳
Wonderful!
Happy New Year! 2024 will be even better!
It absolutely matters that we caused it because that pertains to the source.
Ok true, but it just makes me sad sometimes when that is all we focus on and we don't think about the ways to fix it. But yes, you are absolutely right, it does matter so that we can know how to fix it! :)
@@GEOGIRL
What bothers me is that alot of people aren't learning the science so they actually know for themselves for a fact what's happening, most people don't know where to start and the mainstream is a bunch of emotionally appealing infotainment that really doesn't teach anything except a few factoids that scare people and that causes others to think it's over exaggerated.
Then if someone does try to learn the actual science it's pretty overwhelming, even more so if someone doesn't have a rudimentary education in science. I've known so many people that know absolutely nothing about science and they always want "proof" but don't even know, for example, what isotopes are, so you have to start from square one.
I know nothing about the solutions side, other than get of fossil fuel vehicles, but then the other products and the Intermodal System would still be fossil fuels based, so it seems like a hopeless Catch 22.
Thank you for your videos, they actually help alot.
Thank you for an oo-id free experience.
If you think about the elements that compose us living beings of the biosphere, and that they were once part of the geosphere, hydrosphere and atmosphere, it seems that it is completely legitimate to say that we living beings ARE Earth, just as we are composed of our cells so our cells are us.
Not really a Gaia hypothesis type thing asserting the earth is an organism, but more just however you can define earth, our constituent elements came from that, and are going back to that, so for all intents and purposes we ARE Earth. It's a strange identity trip to think if it this way.
I love your content
Come to think of the ozone layer, its thickness is suspected to keep growing until a vast number of oxygen consumers came up to the Earth's history. Then, it reached an equilibrium. Is it so (very simplistic though)? Holes or thinner layers are a serious concern today ....
Stay enthusiastic…
I chuckle every time someone lets plants die and they tell me they watered them once a week!
Happy New Year 2024
Excellent video! HNY🍾🍾
Is magma considered part of the geosphere, or a different -sphere in itself?
Is it true that more material/stuff is moved across planet Earth's surface by human activity than natural processes (rivers, oceans, winds and so on)?
Then there's xenobiogeochemistry....
Alien hoodoo! ;*[}
So cool, thank you kindly.
Thank you for the content. This is my hypothesis. Had really a hard time understanding the substance on this channel. It puzzled me for a long time. I mean.... Contentwise, teacherwise... Such a beautiful voice... Perfect. But, there is a weird editing that sounds kinda out of phase to my ears. It sounds to me there should be some more temporal spacing between the two sentences, more naturally. Maybe add or leave in some filler words.
In habitid earth is a diverse seal in the norms in pursuit of sign of the times bio chemistry surfaces in wrathful dis array though leaves sentimental values that provide resolution to it purpose
I watched “Nova ancient Earth “
THERE WAS NO SOIL at one time.
Geochemistry is like coal forming.
She correct.
They all interrelate.
Chemistry of ore deposits.
The great oxygenation event makes the ore.
Rachel, is it time to change your name to PALEO GIRL? Paleolimnologists and Paleoecologists love biogeochemistry. Thank you for all the wonderful videos you have made.

12:17 - 12:27 Yeah, my father sez that... and he went to university and took science courses. Mind you he's also a self-denying capitalist, sooooo...
If yeast can kill of their own entire populations simply by producing what are to them toxic levels of alcohol, why can't humans affect changes to their environment that is also harmful to themselves? Ask me, humans are much better at creating ways to inflict on damage themselves than yeast could ever dream of─especially if the relationship between the act that creates the damage, and the damage itself are difficult to detect, or if seeing that connection is a threat to the profits of extremely wealthy and powerful industries.
Pretty self explanatory.
Glad to come across to this so interesting video that taught me a lot about Biogeochemistry. You're incredibly brilliant and so articulated! My huge accolades for your prosperous future. And please, keep doing this amazing job. Be a real blessing to the whole world. 🍾💐🎉🪔
