Thank you for a great video! I agree with you that learning about how these biogeochemical cycles work makes one realize how everyday situations impact the Earth as a whole. For example, we visited family for the holidays at their home in a new housing development. They described how the real estate developer had sold off the first few feet of soil for the entire development, nearly down to bedrock, before constructing. It was quite eye-opening to realize that this entire area wouldn't be able to support any deep-routed plants or any microbes that capture carbon for a very long time as the entire soil horizon needed to develop again. Here's a gift to say: Well done on your doctorate, and congratulations!!! I hope your holidays were good, and that you're doing well with your course and lab work preparations!
Thank you so much Ted! You are too sweet! I have been so bad about getting on to check comments recently, so when I got on this morning and immediately saw this it really made my day, thank you! I hope your holidays were good as well! :D
i realy love the video again! i just share the same interest and enthusiasm with you on the cycles amd the whole topic in general, i think everyone should see this video just to understand how things are working. people are so ignorant about this topic. thank you for making this! i low key wanna see you at startalk with neil. people need to see and youre so good at explaining :D teach the world :D
Rachel: This series on biogeochemistry is absolutely excellent. It’s a subject that I definitely need to be educated on…and it is an extremely important one. I also greatly enjoyed last weeks video. My comments may have been entered to late to get your attention. I know of late you must be exceedingly busy. Best wishes!!
Oh my gosh Don, thank you so much for all your amazing comments! I always see them and then wait to respond because I want to have enough time to give a response as wonderful as your comments and then ultimately I never get that time haha, so I apologize for my non-responsiveness, but you should know that I always read and love your comments :) You always teach me new things as well and I love hearing from someone with as much experience as you! So thanks again, please keep em coming, especially your travel stories, those are great! :)
Thanks for your videos, always very informative although I often go off on tangents on my phone (watching on tv). Today’s excursions were on Yellowstone and bat guano (independent excursions). Questions on is there an extensive lava flow field tied to the Yellowstone volcanic hotspot? And how phosphorus rich is bat guano (very). Thanks
13:51 - I remember somewhere quite a few years ago, Rachel, that 50% of the Earth's nitrates present in the soil are from NO2 created by lightning discharges and the NO2 reacts with water vapour in the air to form nitric-acid.
I can't confirm nor deny the quantification. Photochemistry just above water body surfaces produces aerosols crucial for the biogeochemical cycles. High up above the troposphere are radicals created by phtochemistry that also take part in the cycles. However Rachel covered the most essential cycles perfectly, as always ❤. @geogirl
Great presentation. One nit: On your slide at 12:50, you illustrate CO2 pollution with an image of what appear to be cooling towers. Unlike smokestacks, these just emit water.
Haha I do, thank you so much! I was kind of feeling like this week's video wasn't up to my normal standard, but this comment makes me feel really good about it, thank you for that! :) Also, Australia is one of the top places I want to visit! I think it is so beautiful and there are so many geologically cool places to visit there :D
Geo Girl - How co2 is sequestered through the biogeochemical cycles. Corporate Person - I want this co2 thing sorted fast, cheaply, and profit generating. Especially profit making.
These cycles lead credence to the notion that our planet could be considered in its' entirety as a self-regulating organism which is the central idea of the Gaia hypothesis.
Great video, i was wondering how much pushback you get for teaching man made climate change. Everyone needs to learn this no political agendas involed.
You see, if you pay attention to these videos you start getting the idea why "terraforming" Mars is a BS idea that could never happen due to the complexity of the entire sustainable process. Thanks for the extreme detail, Rachel.
rachel, i've been searching for references for my geography olympiad preparation and your contents are super super helpful!! thank you so much for making all of them accessible and pls don't stop creating. 🤍
You are so kind, thank you so much! I am so glad that my videos have been helpful for you! Best of luck in the geography olympiad! It is already so impressive that you are even doing that, but I am sure you are going to do amazing :D

CHNOPS-- one of Ancient Egypt's most memorable Pharaohs. Happy New Year to Geo Girl!
I like content that ties together information form multiple disciplines. You do that here very well. Thank you!
Excellent vid GG. Will definitely be using this in my science classes, with your express approval, of course.
Of course! I hope it helps your students! :D

You're such a great science communicator. No fancy and unnecesary production, just clean and straight information easy to understand.
Thanks Rachel this was even better than I expected😊

Here here! Keep your field geology stories coming Don!
One of your best videos! Luv bio/geo/chemistry.
All is one. Everything is connected. How wonderful it is to be part of this life ❤
Eye opening and interesting. Thanks!
I’d love to see more videos on biogeochemistry
I find it fascinating learning how life affects/controls the chemistry of the planet, great video.
Great video. I learned a lot 😮
(yes, I use these videos for my own education. Keep it up 👍)

love your content and the purps earth vid is great!
cheers thanks for the video happy new years :).
Amazing video
Fascinating content. Thank you for sharing.

A great video, Rachel, thank you 👍👍

Amazing as usual! Thanks a lot!
Thank you, this was fascinating.
Just watched the biogeochemical cycles videos. Wish i could get our politicians to do so.... Thanks.
Awesome video,
Thank you for your time and efforts.
Great video! 😊

Cycles are my first comment!!
Rachel 🎈,
👏👏👏👏👏.
Thank you.
This is gonna be good🙏🙏
Soo underrated 😢😢
Such an interdependent system, just amazes Me…
thanks!
I've always wondered about salt. Where does salt come from? Why is the ocean salty? But not too salty? How does salt figure into biochemistry?
Thanks!
Thanks so much! :D
Plants, algae and cianobacteria also respire during the day, not only at night.
Do you do this on your own? If you do, you are freaking amazing girl. Thanks.
ps. If you're ever in Sydney, I am at your service ma'am, respectfully.
Haha I do, thank you so much!

12:30 - That should be the Anthropocene, Rachel, not the Holocene.
🤔🤔🤔
I am still no fan of breaking human and animal cycles that don't involve reducing chemical and reducing erosions, but I value your teaching.
Actually, life is cyclical 💐
She's pretty
typical. maybe pay attention to the content. What, are you twelve?
