5 Times Supercontinents Caused Major Diversification & Devastation of Life | GEO GIRL

This really helps me grasp how old the earth is. Continents moving about the speed my fingernails grow and that they have broken apart and come together many times. It’s amazing

Even supercontinents have problematic breakups.

Thank you for another great video! I’ve now been a channel member for two years!!! And I’ve always been impressed by your knowledge, skill and passion for the amazing subject of geosciences, Dr. Geo Girl! One thing that I’ve been curious about concerning Gondwana is its existence as a coherent landmass both before its fusing with Euramerica to form Pangea AND after Pangea’s breakup. That makes me wonder if the rocks in orogenic provinces are much more broken and weaker than in the more stable cratons. So in general when continental rifting begins, it’s much more likely to occur in areas like the Central Pangean Mountains than in continental shield areas. (And maybe that’s why the Midcontinent Rift System failed to break apart North America?) Do you know more about this? Thank you again for your wonderful and talented work!!!

Geo Girl is a super YouTuber! Keep these awesome videos coming! ❤🎉😊

Howdy Rachel, thanks for another interesting topic. Back in my academic days I only remember Pangea and Gondwana being discussed, and plate tectonics only then being more globally accepted. And in my career expanding back to Columbia/Nena. But I suspect Vaalbará might have been larger than we might be able to prove because of continental mass being re-incorporated into the mantle. Look forward to seeing the model of the future Supercontinent. Who will take over after mammals? Birds?

Rachel ⛳, Solid work ⛏️. That was well constructed and super interesting! 👏👏👏👏👏

Loved your video! I recently got down a rabbit hole reading about the supercontinent Rodinia and the Great Discontinuity in the geological record

The possible extinction of mammals? What a cliffhanger ending!

Thanks for another great video! Your star is shining brighter and brighter!

Wow I didnt know there were several super continents, and Pangea is the most recent one. Thanks for this awesome video

Whaast? I didn't know about the first five at all! Why didn't anyone talk about them before? Seems you're the first here, Rachel! Thank you for my weekly dose of geology 😅🌺

You really deepened my understanding of the supercontinents and the mass extinctions around them. I still don't have knowledge of every detail but I have a better foundation to draw on in my readings. Thaks a bunch!

One of your best, this one. I hope your future plans include the writing of books. You'd be good at it. There's nothing that holds the attention quite so well as enthusiasm on the printed page.

Dear Geo Girl. Thank you so much. This video was epic. It's one thing to have these events explained on their own, but having the movement of the continents layered with the extinctions and ice ages and global warming and evolution of life... it all came together beautifully to tell a huge chunk of Earth's story that has, until now, seemed rather fragmented in my mind. It's such a delight to see how all of this comes together. You rock!

Absolutely terrific video. Thank you.

I swear I could listen to this for hours, amazing work breaking it down!

Your videos have become more enjoyable for me as you've gotten more experience making them.

Thanks, very nice presentation

Dang, I can hardly wait for the video about the next supercontinent! But at least I don't have to wait the whole 200 million years to see it in real life.

Love this. I have a Ph.D in geology, but my topic didn’t cover a lot of earth’s history. I appreciate that you don’t glaze over details that a wonk like me requires. :-)
