- When did Pangea form? What mountains built during the formation of Pangea? How did Pangea affect climate and sea level?
Continents colliding near the south pole in the Carboniferous period underwent major glaciation. This Carboniferous glaciation marked the greatest ice age of the Phanerozoic Eon (or the past 500 million years)! Coal swamps characterisitic of the Carboniferous period dried up in the Permian due to increased aridity as Pangea formed. There were two main ways that Pangea caused dryness: 1) much of the land was far away from the ocean, and 2) Pangea'c crust was very thick due to all the conintent-continent collisions, which prevented epicontinental seas from transgressing onto the continents. The dissappearance of the coal swamps led to less organic C burial and therefore increased atmospheric CO2, causing global warming. This global warming brought the Carboniferous ice age to an end.
In terms of tectonics, the Appalachians continued to form along the margin of Euramerica (previously Laurentia) as plates continued colliding with it during the Alleghenian Orogeny, which followed the Taconic and Acadian Orogeny. The Ouchita Orogeny also occurred at this time as a southwestward extension of the Appalchian mountain building collisions. The Ancestral Rockies also formed due to forces associated with the Ouchita orogeny during the late Carboniferous. These mountains caused a rain shadow to their west, leading to large evaporite deposits across that region. The western margin of Eurameria was also undergoing mountain building with the Sonoma orogeny starting in the Late Permian and continuing into the Triassic.

Thanks for making this video! I don't think I've seen a youtube video give this kind of granular attention to the environments of the past and what caused them. I would love to see a series exploring this stuff! Which maybe you've already started, I'm going to go check out your other videos now!
Thank you so much! I am so glad you enjoyed this video, and based on what you said, I think you may like the other videos in my Earth history / historical geology playlist. It is all about the environments in the past and what caused them :D
I think it's absolutely amazing that an entire separate mountain range existed before the Rocky Mountains, in the same general area, then completely eroded away. It's also fascinating that both mountain chains were formed while the area wasn't along a continental boundary, but resulted from plate impacts further southeast and west. Geology is so cool!
But I'm a little disappointed that you talked about the Guadalupe Mountains right near where you live, but you didn't go show some geological features there. That would be a GREAT addition to this geology channel - a geology field trip! We need to see you wielding that geology hammer and hand lens you always mention in your video notes!
Eventually (probably after I graduate lol) I hope to get out and do some field videos! :D I would love that too, I just don't currently have the time or finances to do that, but I know someday I will ;)
@@GEOGIRL possibly you could find some photos of larger geological features
The Ancestral Rockies and the Laramide or "Modern Rockies" likely share a crustal weak zone in the Precambrian basement rocks..
@@GEOGIRL there is a hike in Guadeloupe Mountains National Park that comes with a little paper pamphlet guide to help find about forty unique and distinct fossils embedded in the rocky wall along the way up. They’re far more numerous than that though because it’s actually a massive fossilized coral reef
(Typing as the video starts to play) I'm more team Gondwana but it's hard to not like Pangea, it was weeeeeeeeeeeeeeeird. It's like a Sci-Fi fantasy "World" for DnD. You could walk from Pole to pole!? The inside is composed of a mountain-Ringed Desert, You can plop every biome on a single "island" (Shallow seas, bay-bee!). And that's just the Continent! What the heck were ocean currents upto!? Can you imagine the weather systems as air-masses come crashing down on those mountain ranges!?
I love your enthusiam about this! I share this excitement and agree that it WAS weeeeeeeeeeird ;D hahaha
I wish I could've been there just to see what the weather was like!
@@GEOGIRL Shame most peoples' reaction to ancient geology is "Okay. 😐" Butbutbut! The way the iron is locked inside means that the magnetosphere was the reverse of what it is today! // The coral growth indicates that the earth was spinning '17%' faster! // The calcium decay and mass die-off is due to ocean acidification from CO2 being dumped into the atmosphere due to burning coal deposits in a large igneous province! The same thing is happening today-kindof- THE ROCKS TELL THE FUTURE, MAN!
Absolutely fascinating stuff! This is fast becoming my favourite channel.
Aw thank you so much! I am so glad to hear that ;D
There seems to be a "trope" of NA being split by some sort of inland sea (sonoma, western interior). I wonder if it will happen again.
You are so good at explaining this stuff. Thank you!
Thank you! ;D
Great video as always!! Spending Sunday learning with you is very good and relaxing!! A hug from Brazil!!
Aw thanks, I'm so glad you enjoy learning with me, I'm hugging back! ;)
For some reason I am totally gobsmacked by geology and having traveled through these regions I am totally transfixed by your videos and can keep up with your pace! Keep it up! Love it. Understand what it took or you to be able to create these videos!
It's been a long time I have been watching a video of yours due to my busy schedule I have yet to watch all your previous videos from May ! Haha
Oh wow! Well I am glad you came back and I hope you enjoy catching up on the videos you missed ;) Thanks for the support!
There was only one continent and there is only one Geo Girl! ❤🎉😊
I just came across your channel from a recommendation. I really enjoy how you implement the graphics into your videos. It syncs very well and provides a lot of insight as you are going over the information. Very well done. I would only say that once you get going the narrative is very fast and continuous. I know you are covering a lot of information in each video but if pausing a bit between divisional subjects under the main topic or slowing down may help the pace. After a few videos I found myself zoning out to the drone of some much talking. But really, a super channel and as I stated, the insertion of the graphic content is extremely well done!
It will be helpful for us who are trying to get familiar with this material, for you to continue through your talk, to keep referring to how many millions of years ago are these geologic eras, as you refer back to them. Thanks. Keep up the good work!
Glad to see you again with another awesome geology knowledge..
Another small point,... I'm perfectly happy for you to use term "coal swamp", as coal will eventually form from the sediments deposited in that tectonic setting (assuming environmental conditions are favorable), but strictly the organic matter rich sediments initially deposited would be more accurately described as peat not coal. The transformation from peat into coal takes place as the basin subsides and the peat becomes buried by overlying sediments. At the increased temperature and pressure beneath the surface, the peat is transformed into coal through a process termed coalification.
Most of the major coal deposits in the world accumulated in foreland basin settings, which form between tectonically active mountain belts and the adjacent continental craton, due to downward flexure of the continental margin.
But I think you covered it in enough detail. I was just adding additional info in case anyone's interested, which they probably won't be.
Yes, this is a great point! I didn't make up the term coal swamps, it's just what we call the Carboniferous swamps because they ended up generating so much coal after burial, but this is a great point to make so people are aware that the coal is actually only generated after millions of years if the rihgt burial conditions persist! :D Thanks for pointing this out!
I learned a lot - thank you for putting this together.
Came for the Europa videos, stayed for the Geology. There is ALOT of great content here. Keep it coming, but please don't burnout.
Oh my gosh, you are TOO kind! Thank you so much for your generous donation and your kind words! I will keep it coming for as long as I can! And considering CZcams is my break from my real work, I don't think I'll burn out any time soon ;)
Thanks again!
@@GEOGIRL You're quite welcome. Thank you for the knowledge.
Great great great video!
Thank you! ;D
Thanks. Ever since Geo 1 , I wondered about the super continents. .. a subject I couldn't find much on... but now it looks like more is now known and available . Yeah EP and White Sands Geo is interesting. Used to live there. Go UTEP.
Really cool to see how all these mountain ranges on now-separate continents were connected to each other
Nice video, missing more global event for that time period, keep up the nice work.
Loved it ❤❤
Nice look...geo girl...🙃
Hooray! Sunday is GEO GIRL day! (I hope that doesn't sound blasphemous!) But hold on... You have 12.1 K subscribers?!? Didn't you just pass 10 K last week? That a 21% increase in subscribers in ONE WEEK? 😳 That's amazing, and well earned! Congratulations! Look out, PewDiePie, or at least, Dr. Becky; Geo Girl is coming for you! 😄
Hahaha Yea, my channel is growing faster than it ever has but honestly even though it's amazing it's a bit stressful as well! I am a people pleaser but I am quickly learning that it's not possible to please everyone haha, but I'm sure I'll eventually come to terms with that
YES MORE GEO GIRL CONTENT I LOVE
Yay! So glad you enjoy my content ;D
Thanks!
Nice and informative video ..😇💫😇😇✨
Thanks so glad you found it informative ;D
@@GEOGIRL most welcome...D✨✨🙃🙃🙃
Wow, algorithm brought up this video, probably because i'm a fan on PBS Eons, and your channel is so cool! Thanks for giving us entire geology lessons in an accessible way for free
Great content. You are so entertaining to listen to!!
Thank you! I am so happy you enjoyed it :D
Will watch later but I'm rooting for it: Pangea is my favoritest continent ever and what you have to say about its tectonics sounds extremely interesting.
Gotta love Pangea!!
Thank you! Subscribed! 🎉
Thanks! So glad you enjoyed it :D
Very nicely explained ❤️.
Thank you!
@@GEOGIRL why Permian triassic mass extinction does not take place in early Permian as pangea was formed , and very hot climate existed?
Thank you for making my Sundays a lot more enjoyducational 🤓
You mention coal swamps a few times. I recall one astonishing article in Scientific American from about a decade ago: "Coal ash is more radioactive than nuclear waste'. That one really blew my mind 🤯
Take care GeoGirl, see you next Sunday 🖖
Haha I love the word 'enjoydeucational' ;) Thanks so much! Can't wait to see you next Sunday!
I love that there's a time period called the Mississippian.
that's cool info.
Thanks! I agree :D
I have yet to visit the Guadalupe mountains but in 1995 climbed the Cretaceous El Paso Franklin mountains to find an old plane wreck (which years later was rediscovered and became quite a sensation in the El Paso news).
I love your nerdy blanket haha!
I can imagine being able to visit any place and time in a reasonably survivable environment suitable for observation. The scenes I see are beyond beautiful for some, while a danger is there with the beauty and your moments daydream could be suddenly fatal.
Still, the Western Seaway approx. 75 million years ago would be spectacular for 2000 miles north seeing the environments and creatures all along especially westward and the islands all along an ancient coast. Imagine the variety of fauna native to these areas. A click following setting the next coordinates and millions of years forward or back, would take up the rest of my life.
Didn't realize you were in El Paso. I can see why you would get into geology living there. That part of the country has a good view of the Earth's bare bones. Gonna dig through your videos and see if you have one about the Colorado plateau and the Rio Grande rift.
I've talked about the rio grande in passing in videos before, but never a full video on it, nor the Colorado plateau, but I got them on the list for future videos! ;)
Before I watch any further, you really rock. I've been wanting to know these things with the information laid out plainly and succinctly, so you are providing a valuable service for wannabe amateur egg heads like me. Thanks a bunch! Oh, and you're my hero. You be THE Obi-Wan!
Aw, thank you so much! This is so sweet, I am so glad you you enjoy my content ;D
Thank you for this information. I had wondered about the banded coal seams in West Virginia, where I grew up. I could see that the coal seams were covered by sedimentary rock but, Why, was never explained to me. That there were many periods of glaciation on the south polar regions making for sea level changes and thus climate changes and recurrent swamps and sea water incursions and other events, was never explained to me. Now I understand a little bit better.
So glad to hear that! I love it when suddenly the rocks around you start to make sense and open your mind up to all the amazing things rocks tell us! That happened to me when I moved to El Paso and learned about the mountains here, it is just so cool to know what your are walking on ;D
Avenge the Permian Extinction! Let trilobites reign!
That's a sick blanket
I live in Missouri and love to study the St Francois mountains in southeast Missouri. The core of the Ozarks.
Very interesting, Tectonics is my favorite subject all the time.
It's hard not to love! It's such an amazing phenomenon and has such a large effect on Earth as a whole! :D
@@GEOGIRL it's hard but more interesting. If tectonics activities are not happen than existence of earth is not possible.
Cool channel - just found it. Geologist. Drilled hundred of Pennsylvanian, Mississippian and Devonian wells in Oklahoma. Keep up the good work!
Oh my God I just heard the part where you live in El Paso. I grew up there and got both of my geology degrees from UTEP. As a matter of fact, my advisor was Libby Anthony. How cool is your channel?? Ha I'm super excited about this. Have very similar interests.
Wow, that's awesome! Yea, Libby is great! What a small world :D So glad you found my channel, I love finding fellow UTEP students and alumni ;D
That is awesome! Ha! This isn't my real name btw. I'll try to find you on LinkedIn or something as my real self. Super cool that you're doing this. Great content and you have a real talent for these videos. Keep it up!!
Kitty!! (At the end) 😀
Plate Tectonics is so fascinating. The Mountain building aspect is incredible! I live in Tucson... right to the east of the city is the Rincon Mountains, a small range, highly eroded.
It's been said that the original Appalachians curved along the southern states, and that the Rincons are the last remnant of that...
Any truth to that, Rachel? Just sounds too incredible, and more like State Promotional hype.
Oh that's interesting! I'm not sure, I don't know much about the Rincon Mountains, but I'll look into it, I would think it is definitely possible that they were an extension of the ancient Appalachians if they were part of the deformation that the Ouchita orogeny caused in the southern states :) However, the Ouchita mountains still exist (even though they are largely eroded) so I'm not sure the Rincon mountians count as the 'last' remnant, so maybe that part is a tad promotional haha ;)
@@GEOGIRL Exactly what I thought! We've got the "big hole in the ground" why make up Mountain stories?
Although you sounded like there could be a shred of truth....
Hmmmm! 😲😁
My fave 2 periods
So cool -Soon to be -Dr. Geo Girl! I just got back from the Appalachian area of Kentucky soooo beautiful. What are your thoughts in the Cumberland Gap area?
I actually don't know much about the Cumberland Gap area is but I will look into it and maybe make a future video about it! ;D
Thank you there is something to do with a meteorite.....and access to the west way later i guess =)

Thanks. Being a humble noob from Avalon I would love to understand the rock record diagrams that appear in your slides more. I guess they must vary depending on the part of earths crust they focus on but does the horizontal variation show how easily that rock erodes?
I figured the Permian basin would make an appearance in this video
Nice overview of the time period. Sorry you didn't mention the Mojave, Yavapai, and Mazatzal Orogenii making the Southern Rockies chain. The Paleoproterozoic Era was a fun time to be in New Mexico!

Earth at the time: What's a horse?
BTW the Uncompahgre uplift is my neck of the woods. It's infamous for causing plane crashes because it looks flat but isn't. If there's cloud cover, pilots who aren't familiar with the area will run straight into the terrain.
I lived in Val Verde county for many years.. The surface is primarily caliche (hard packed limestone) that I assume was originally under an ocean. I just got back from a motorcycle trip to Big Bend and the Fort Davis region so your presentation answered some of the questions about the local mountains and surrounding geology. Much of the rock has a rough red-brown hue that suggests vulcanism. These are surrounded by much lower desert plains which suggest they were part of the inland sea of what is now North America. I assume from your presentation that the mountains are remnants of the Ouachita range. Was this area very volcanically active as Gandawa and what would become North America began to collide.. Was there oceanic crust that subducted under the two plates as they collided?
Rather startled to see Delaware Basin so close to the Guadalupe Mountains, but it's in western Texas.and southeastern New Mexico. In fact, Carlsbad Caverns are at the boundary.
Living in Denver, I can tell you that the Rockies still cast a serious rain shadow.
Good cross-reference for paleontology videos which often fail to mention where the land masses were at the time. BTW: say Ung-come-PAHG-ray. ;-}
Thank you for the kind words and the words of wisdom regarding pronouciation! Hahaha I always appreciate that so much :D
👍😀😀
If you could go back in time, Rachel, what would be the ideal part of Pangea to live? That is, not too hot, not too cold, not too wet and not too dry.
I need that T, it's so cool
It's one of my favs! ;D
Really.. excellent 👌👌👌
Very nice presentation....
Geo Girl is doing wonderful work for Geological fraternity and especially for great lovers of Geology....
Tons of appreciation and Godly blessing from India...
The most important thing I liked in this presentation is the "Patience" with which you have delivered this topic without missing any minute detail...
Great work.....Keep going
From the looks of that you could cross from Wisconsin to michigan with out going over a body of water
Uncompahgre - ("Un -com-pah-gray") named after the Ute named river that runs through the town of Ouray ("You-ray") Colorado and northward toward Montrose Colorado.
Thank you! I appreciate this! As I cover very specific scientific topics with very specific terminology, it is often hard to find pronounciations for these things online ;)
It is not setteled that increased GH caused the mesozoic warming. This is of the often occuring hen egg question. I think that the CO2 was absorbed by the Karoo ice age and when Antarctica left the pole, the albedo drasticly dropped and Antarctica melt and the warming oceans released the CO2 as a RESULT. In this video too, the tectonical movement as a global temperature FACTOR is not displayed. Which is suprising since we later on (now) see that when Antarctica moved back to the south pole, our Ice age began, which is well documented.
Yea, I am sorry, I should've mentioned that, I think I already discussed in my Carboniferous ice age video and many other ice age/glaciation videos about how the position of the continents over the poles affects climate, but I should've mentioned it here too, my bad! Thanks for pointing that out :)
@@GEOGIRL Thank you for staying open minded and kind! I am just kind of obsessed with the origins and geologists are the ones that go the core.
Not sure how I missed this one! Still, here's a like and comment for the Almighty Algorithm. 😊
Thank you ;)
23rd!
19:45 - Pangea kind of reminds of Westeros from Game of Thrones, Rachel;).
A mountain range so close to the equator would have some major climate implications and smack dab on the ITZZ, probably leading to a cold and wet Nothern Hemisphere and a drier Southern hemisphere, and also creating a lot of major river systems as well as so many microclimates.
This had to be a contributor to the mass extinction, since it would probably have lead to the evolution of many species that are narrowly adapted.
I heard of Pangea in my 80s youth! I use it as my empire name in my galactic exploration/empire game - Space Empires IV! When I moved to Poway, San Diego(from W.S.M.R - New Mexico around 1988), i ran into a fellow Navy brat who I actually met when I was even younger up in Monterey! Anyways, he had this Imperium Galacticum game which we'd play. I can never find that one; this Space Empires IV which is now long ago defunct is the closest thing I could find! And, I always use Pangea as my empire name!
Oh yes - have you heard of the latest ideas that the Earth's(and our solar system) going around the Galaxy caused plate tectonics? It's one of the big news items over the last week or two!
Oh how interesting, I haven't seen that, can you send a link?? Thanks!
@@GEOGIRL looks like youtube deleted the link. I've seen this before; i've been posting the latest nanotechnoloyg news at this one youtube, and then they started deleting my posts. I eventually guessed they don't allow posting urls anymore, for some reason.
Which is why I had previously tweeted some articles on your twitter; but, you don't seem to check your twitter account!
@@oker59 Hahaha I am so sorry, I never get on twitter or really any social media platform other than YT lol I am so bad about that! I actually have a video coming out in a few days where I talk about why I really don't get on those platforms much😅I will eventually check it, I am just so slow lol
@@GEOGIRL well, some people get too hooked on social media. It's like people who walk around with their smart phones and don't look at the world!
I didn't get into smartphones till maybe a year ago. And, I have it on a monthly charge thing(which reminds me, I need to pay for another month . . .). I just don't want to get on an automatic payment thing I can't turn off!
I'm still not that into the smartphones thing.
I remember when I first got onto facebook; for the longest time, I didn't have a picture up, or had posted anything. Now, I've got all the greatest astronomy pictures, a whole bunch of blues/rock best ofs, and all my favorite movies and books(they don't allow you to update new books anymore - weird!)
I got onto twitter to follow the Ukraine war thing back in 2014. I don't know when, but I soon set up tweet bot to tweet out my favorite mathematical quotes and science videos and such. Then, they suspended me because of my use of tweet bots I think. My twitter account magically came back online like a year or so ago. I still haven't tried to get that back up and running. I heard they had a debate about tweet bots, and decided to allow them.
I'm attempting to pin down the origin of the lime and sandstone of the Mogollon Rim in northern Arizona. I can't seem to get a clear understanding of it other than it being a product of the Carboniferous and Permian periods.
Nice, but I think CZcams takes exception to your explanation of Carboniferous climate change, with them claiming that climate change ~300-ish million-ish years ago was mainly caused by human activities. Ether way, thanks for your videos.
9:30. Laurentia is AFAIK the craton. Euramerica is the continent composed of Laurentia, Baltica and Avalonia. So the figure is OK, it just marks the craton.
Oh that makes sense, thanks for that clarification!
Have you done or plan to do a video about the history of New Zealand's geology and how it originated (I'm a New Zealander)?
No but that's a great idea for a future video, thanks!

@@GEOGIRL If you get the chance you should come and visit New Zealand as it has a highly varied geography and is beautiful, this highly varied geography was one of the main reasons why the "Lord of the Rings" and "Hobbit" trilogies were filmed here.
@@GEOGIRL In addition to New Zealand's geology you could also do a video about NZ's unique animal and plant life, for example NZ has only two endemic mammal species - the Long Tailed Bat and the Short Tailed Bat. Also we also have many unique bird species such as the Kiwi, Kea and Kakapo also the last remaining species of the Rhinocephalian order, the Tuatar ( en.wikipedia.org/wiki/Tuatara ) is found here.

Meowing too loud?! Awww, I completely missed it. (Bummed.)
Small question with all the cratons on one side of the planet does that mean the Earth wobbled along on it's orbit? Further would that mean increased volcanism as the moon, sun , plus Jupiter's gravity caused mechanical heating of Earth's magma?
doc geo could you talk more about oxygen levels in these days? if we went back then as humans in a time machine could we breath ok?
Yep, pretty much any time from about 500 million years ago to today, we would breathe fine (the oxygen levels were relatively similar as today ~20%) But before 500 million years ago (from about 4.5-500 million years ago), we would've had a very difficult time breathing, especially before about 2.2 billion years ago, back then there was vitually no oxygen and also no ozone, so we would not only choke but also burn haha
HI Geo Girl, very nice, but please take a look at this too poike's theory,
Someone told me that the mid continental rift that was forming in the middle of North America only stopped because of the collision with Africa. Is that correct?
Sooo . . . The classic Zen Master koan mystery question goes waaaY back.
_"please show the sound of one hand clapping"_
What planet could be better to visit than Earth in the past?
Mars!! Apparently a few billion years ago, Mars may have been a paradise filled with life! (I don't study Mars personally, so I could be wrong about this, but I am pretty sure I heard this from Mars researchers somewhere haha) Maybe in the future I will do some research and make a video about Mars' past :D
@@GEOGIRL Good points and you could do a good job with the geo history of Mars. But while we hope there was and is exciting life elsewhere, we know it was was there on Earth. I still would prefer time travel than space travel.
According to CZcams & United Nations context warning box, they indicate humans lived during the Carboniferous period. I guess that makes sense considering if it wasn't for humans we would still be in snowball Earth.
Reason of ice age on earth please tell
Sun cycles, earth wobble, location of land masses and warm and cold oceanic flowage routes.
Small point, but for a not very good or compelling reason, the "Alleghanian Orogeny" is spelled with an "a", not with an "e", as in the Allegheny River, the Allegheny Mountains, or Allegheny County, PA ( where I was borned). Someone (I forget who now)... maybe John Rodgers, got too clever by half, and decided to cause unnecessary confusion. 🙄
Oops! Haha thanks for catching this and letting me know ;D

I love how google finds it necessary to leave a giant disclaimer under most of your videos as if you are discussing/disputing anthropogenic climate change.
"Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels." That's not even a correct statement. They are confusing natural climate change with human caused climate change. 99% of the climate change in earth's history had nothing to do with the actions of humans or the burning of fossil fuels.
Hahaha I know, everytime I have the words "climate", "climate change", or "global warming" in my video or video description it puts that disclaimer no matter how many millions of years ago I am talking about! 🤣
I thought Orogines was a Greek philosopher 🤔

Haha well I gues there's two meanings then lol
@@GEOGIRL lol
Thank you for the fascinating video.
Wish my old brain could keep up and retain the info. lol
No idea if this is at all relevant, but would a single continent like Pangea have a smaller area of continental shelf than the current disposition of continental masses.
If so would that have any impact on mass extinction event having such a devastating effect on aquatic fauna?
the earth has an orogenous zone :)
@@eaudesolero5631 LOL it actually has many! 😂
omg haha I'm almost embarrassed. I was sitting here watching this over again, and as the video "you" was lecturing away I was watching intently, nodding at each new point like you were really talking to me haaaaah
Ah, I love that! I am really talking to you, the only difference is I can't respond to you in real time, but maybe someday, I do live streams ;)
@@GEOGIRL truly
Are you working in NASA?geo girl??
Hahaha well I did a NASA internship over the summer, but no I don't work for NASA lol
I actually filmed the last couple videos a few weeks apart and it's just a total coincidence that I was wearing the same shirt and then posted them back to back😅
@@GEOGIRL ohhhkkkk...😅😅😅👍👍👍I thought... you are wearing NASA 's t-shirt...so hopefully you in NASA...😃😃
But no doubt.. you are so talented..and I hope... you will work in NASA..🙃🙃
@@ramchauhan5238 Thanks, I hope so too! 🪐
@@GEOGIRL yes...my best wishes with you...✨🙃
Hello geo girl how are you?
Hmm. Wonder what's so controversial about the geology of Pangea that CZcams put up a 'Context" box about climate change? :P
Hahaha it just does that automatically for all the videos in which I say the words "climate", "climate change", or "global warming" no matter than time period that I am talking about LOL
90% of the video is reference to other videos and later slides
Very well done though inevitably it has an American bias and the actions taking place in the former Gondwana and its consequences are largely ignored. A pity. Perhaps they deserve another video
I know, unfortunately I am at the mercy of my textbook that was written with a slight american bias. But I do plan to do more videos life this in the future, hopefully using references that focus more on other regions! ;)
How utterly ridiculous for CZcams to tag this video with a climate change context tag.
I vote down every one of these garbage videos. No ad money for CZcams. I love it.
Show me some skin .......
Na nevermind 🤮
Bad sound fast presentation weak screen material and a class like presentation. You are great and knowledgable but cant get any more followers with this level of Quality
I actually just made a new video that will be coming out in the next few weeks explaining why I make my presentations this way (with ppt) and how I plan to work on improving them, it's just that at the moment, I don't have the time or financial resources, so it'll be slow going, but these things will improve. Thanks for the input ;)
Oops, I must not have heard about this rule, because I just subscribed anyway. Good stuff is good stuff whether it was made in Power Point or by Marvel Studios.
@@danielkunigan102 u live n learn
Don't pay no nevermind to @OnurOzuvar. It was a good presentation, and you'll learn as you go.
