@@Sheepdog1314 In my opinion, the best textbook out there is this one: amzn.to/47VNed8 However, it's a little old now (two of the authors have passed away) and if you preferred a newer textbook, I would recommend this one: amzn.to/45UFDcR
If I wanted to take a crash course on Geology would a certificate be ideal OR are watching these videos informative enough to get a good understanding ?
I'm a mature Earth Science student in the UK and just wanted to say this is one of the best lectures on volcanoes I've seen on youtube. Really professionally put together. Many thanks and greetings from the UK.
Teaching online is not for everyone. With Paul Day, we see a non-traditional teaching with a mixture of illustrative figures, non-exhaustive accompanying text and well-targeted videos to experience the geological moment with emotion. In addition, the transition between parts of the same chapter and between slides is fluid. We are witnessing a demonstration of the effectiveness of on-line teaching which can replace face-to-face teaching in certain soulless lectures that are too old. Thanks a lot Paul Day.
Thank you so much for this marvelous summary . I love volcanoes and am doing a lot of remote sensing concerning their activities . Hearing you talk about them was like listening to stories about my favorite friends . So thank you very much . I appreciate your educational efforts . This should be made available to kids in school . It's just such an exciting topic to learn more about.
Thank you so much for the kind feedback! I hope anyone, including younger kids, who wants to learn about geology will feel free to check out my content. Originally I was just recording for my own students, but now I record with all learners in mind.
I have been reading so many books and enrolling in so many online courses in geology. May I say your RU-vid lecture series is the most comprehensive I have ever stumbled upon; I will stay on his channel till the last episode. Fantastic, thanks for sharing your knowledge.
Wow, thank you! I’m currently expanding and updating a bunch of videos so I hope you’ll be around for when I post those as well. Thanks for studying with me.
Thank you so much for your videos. It's not easy to teach in front of a screen but you manage to engage your audience and share your knowledge in an interesting and understandable manner. I really appreciate it!
You are a rock star in the educational space!! I got interested in mining and exploration a while ago and had no education in geology. Watched your videos and took notes which expanded to a 140 page document. I would love to see a couple of videos on mineral deposits (Porphyry, Skarn, CRD, Epithermal, VMS, Sedex, ...)(Gold, Silver, Copper and polymetallic Ag, Zn, Pb deposits) and a video on calc-alcaline and thoelithic magma series. If I may suggest a slight improvement to the lectures: consider making the background images in your slides a bit more faint/transparent to increase the readability of the text. This is not an issue in several of the videos but for example "Geology 23 (Geologic Time))" is tough to read. Pretty intense backgrounds there. Keep up the good work Professor :)
Thanks very much for this series. I’m taking my first geology class right now and this has been a great reinforcement for my class. I’ll be referring back as I continue my schooling.
Incredibly interesting and very well presented!! I am working through all the different episodes in this series! Thanks for creating this series of lectures!
Wow! You’re still going! This is great! I just started your lectures randomly, earlier this week, and whenever I thought to look they were all older videos. I was just trying to identify the rocks that I use for my artwork, but now I know a bunch more! I’m a street vendor of tourist trinkets that I make with mostly local (Maine) rocks. I get a ton of questions and now I can answer a very great deal of them. Thanks!
Erosion is an incredible phenomenon. That eroded material has to go somewhere, and today most all of it eventually makes it to the Gulf of Mexico, slowly infilling that basin!
That's one of my favorite airplane videos... whole plane lights up from the friction created by volcanic ash! Shuts engine's down, then fires back up when the ash cooled in the engine! Awesome
@@EarthandSpaceSciencesX I feel the same way about Yosemite except that I recommend visiting in spring or early summer when the Falls are at their best.
Aww man. I like to put on educational videos to help me sleep, but I made the wrong choice with this. Too interesting! It's 2am and I'm still awake. I'm saving to my watch later cue and finding something about wolves maybe.
1:01:32 is a great analog for plate tectonics. I think Harry Hess wrote about his observation of this phenomena back when they were arguing convection as the main driving force of plate movement.
@@EarthandSpaceSciencesX You can also demonstrate this with hot cocoa and milk in a pot. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CBNG0ncKkE0.html
Enjoyed the info. As you ended with extraterrestrial volcanoes, I remembered hearing of an "ice" volcano in our solar system -- just curious what that is..... Thanks!
An interesting tidbit. The day before the eruption, teens were planting trees on the north side of the mountain, the part that the bulge slid over. I met one of those tree planters who the day of the eruption was now out planting trees on the south side of the mountain. Had the mountain erupted a day earlier, all those tree planters would have been killed along with the loggers. The loggers were off work because it erupted on a Sunday. Thus the death toll would have been in the 100's.
Thanks, I am glad you enjoyed it! You are absolutely right of course, ardente literally means “burning” (I speak a bit of Cajun French) but the geological encyclopedias typically translate it metonymically as “glowing.” When preparing the presentation, I had to decide between which to go with based on which one was likely to get the more corrective remarks. Here’s an example for “glowing” from the USGS: www.usgs.gov/communications-and-publishing/news/earthword-nuee-ardente
Your vids are such great presentations covering awesome stuff although i can find but one "fault" with this particular one. The word Extinction was not mentioned once. =-( I was waiting for it... lol. I'm sure you cover that in another video so i will happily keep watching. =-D
Can you please add a link in the description to access the presentations you use for teaching in the Geology playlist videos. It'll be really helpful for revision. It's a humble request Professor ❤
Thank you! I am dealing with a health issue at the moment but once I have it beat I plan on making a lot more content. Hopefully you'll enjoy that as well!
I think we need better terminology than _andesite caldera_ vs _rhyolite caldera_ -- as I believe Mazama's caldera-forming eruption was of dacite and/or rhyolite, correct? Stratovolcanoes can erupt rhyolite, although most commonly they erupt andesite. I do understand the difference between the very large calderas along the Yellowstone Hotspot track formed by high-end VEI-7 and VEI-8 eruptions, and calderas formed by high-end VEI-6 and small VEI-7 eruptions at locations where there was an existing stratovolcano edifice. But, stratovolcanoes can develop inside very large calderas that were formed by earlier VEI-8 eruptions. Subsequent VEI-8 eruptions may begin as plinian eruptions from stratovolcanoes that formed inside the large caldera, correct? And then when the VEI-8-scale caldera collapse occurs, the poor little stratovolcano is obliterated.
I agree, it’s not the best convention because it ignores the complexity of magmatic differentiation occurring within most volcanoes and the resulting landforms/eruptions. I sort of hint at that near the beginning of the lecture when I mention there is a spectrum of volcanic processes and landscapes. If/when I do a series on volcanology I would go over those volcanic nuances.
I have not done a chemistry series yet nor have a I found a good series of lectures online that I would make a playlist out of. Perhaps I should think about that.
Olympus Mons can really only form on a world that is not experiencing plate tectonics. Mars is believed by many to have had some type of plate-type movement during its early history but stopped due to planetary cooling. As such, volcanoes like Olympus Mons could grow to great heights because plates could not separate it from its magma source.
Thanks for the kind words! Indeed, volcanoes are really fun to study and learn about. May even do a full series on volcanology at some point in the future. Who knows?
Not a good idea to talk about Kilauea being a "relatively calm" volcano. After all in 1790 it produced a VEI 4 sub-Plinian eruption with significant pyroclastic flows and killed about 400 people. So Kilauea can go off with comparable force and danger to Mount St Helens.
It's true that groundwater getting into the magmatic system changes the rules for all types of volcanoes, including the 1790 Keanakakoi phreatomagmatic eruption at Kilauea you are mentioning (I've seen the victim's footprints in those ash beds in Kau). Aside from the 1790 eruption, Kilauea is overwhelmingly in the VEI 0-1 range.
Calling that place an island is like calling the sky's friendly! I really don't want to see anyone in Hawaii crying when their house burns! You asked for it!
That's not Monserat... I'm sure I butchered... those poor people have no choice where they live, I'm not rich enough for Hawaii! They do have a choice and choose the beautiful death trap!
Thank you very much! I am using all your lectures for my study. You refereed to lecture notes. Could you send me some? I cannot find your email or any way to contact you - that's why I write here in one of your recent lectures. I would accept any study material. Thanks again - so clear and logical! / Nina - Sweden
