In some places, the rocks below the Great Unconformity are about 1.2 billion years older than those above it. This missing chapter in Earth’s history might be linked to a fracturing supercontinent, out-of-control glaciers, and maybe the diversification of life itself.

@MatthewSpencerKociol 4 года назад
well it's not THAT freaky. This whole video can be summed up as "one day a giant glacier formed, and scraped a billion year's worth of dirt and rocks into the ocean, and like primordial fish food it just boosted the ocean with new and diverse life forms!" Not that crazy when you consider all those big canyons out in the western states formed by Glaciars could be made in a few million years, and sometimes in just a few thousand years! By geological standards glaciers move pretty fast!

I literally JUST got done lecturing on Proterozoic climate, and as this is my first time teaching Earth History, I'm always looking online for assistance and I couldn't have done any better than this! The complex interactions between plate tectonics, volcanism, life, the atmosphere, and climate are hard to grasp (both today and in the past) for students, so I love having multiple sources (me, my textbook, some great videos) help me to teach these topics!

I love the hypothesis that changing ocean chemistry made the larger, harder bodies of the Cambrian possible. It makes a lot of sense--the biological processes that create biomineralization would have an easier time concentrating insoluble salts from ocean water if those ions are more abundant. As ocean chemistry changes, crude and weak biomineralization processes could be gradually improved by natural selection until they are tolerant to much more scarce conditions. A really beautiful concept.

I just love this show. The way it makes me look at the extraordinary past of our amazing planet, as well as the awe inspiring & vast lineage of organisms stretching billions of years behind each of us. It's so wonderful to look at the beauty of nature, learning from it instead of just exploiting it. It's an anodyne to the cynical worldview that the modern world sometimes imposes on us. An interesting aside, Sponges (as noted here) are truly amazing animals that were among the few multicellular organisms that survived "Snowball Earth" (possibly from living in the warmer waters near hydrothermal vents). There are a truly staggering 10,000 (at least) Porifera species alive, today - with many more in the fossil record. (This is actually a pretty damn big percentage of all animal life!)

The average for that is 10 alright? Now there are 1440 minutes and a day and 10 times 122 is only 1220. Therefore by subtracting those numbers you will have 220 minutes left of the day. Which is exactly 3.7 hours. Which means you will most likely finish these videos after 20.3 hours. Now this isn't exact but it's as close as I really care to get. So as long as you have all day and no life at all. You could feasibly finish all these videos in less than a day.

I don’t know why I think looking at geology is so cool, just the fact looking at rock layers like in the Grand Canyon tell a story of Earths history. It’s really interesting. But I think it maybe both theories, rock drawing CO2 cooled the planet into Snowball Earth which caused even more erosion stripping the planets history. However still lots of unknowns.

No doubt Clarence Dutton was an influential man, but he was only building o-n the work of the Scottish geologist James Hutton from around 100 years before. It was Hutton who discovered "unconformities" and ushered in a new era for the science of Geology based on the presupposition of uniformitarianism. No doubt a helpful idea at the time, but a fresh appreciation of catastophism is thankfully making a mark in recent years.
@georgefspicka5483
@georgefspicka5483 4 года назад
As the head of volcanology for the United States Geological Survey, Dutton was probably aware of unconformities via the book “‘Principles of Geology,” which was published in 1830 by another Scottish scientist, Charles Lyell. Much of it’s content was based on the papers of James Hutton. Charles Darwin took volume 1 of the book with him on his voyage around South America.

I believe that this area also has the tallest waterfall, by some measure, located at Hemmed in Hollow, in Arkansas. The mountain also has the Buffalo river and many other waterways.

@Zack_Taylor
@Zack_Taylor 4 года назад
@@joshuadeyoung5540 Maybe you're being hyperbolic, but there are a ton of reasons we know that not to be true. This was before the cambrian explosion, so the idea that during that period, life went through a similar diversification process incredibly quickly and developed intelligent life doesn't really add up. On top of that, there are plenty of marks on earth left by humans that could arguavly still be detectable after an event like this. Plastics and nuclear explosions stand out as being something that there would probably be some evidence of left over. It's conceivable that that evidence could have been lost, but just adds to the implaussibility. The lack of development of life that we see in the records immediately after this gap is the main reason that it seems impossible.

@3gunslingers

Ocean sediments I would guess. But since the oceanic crust is "recycled" relatively fast in geological terms we have no trace of those old sediments. When the oceanic crust gets pushed under the continental crust, it takes the sediments with it.

If both hypotheses of the Great Unconformity have their evidence, couldn't both be true? I.e. the breakup of Rodinia caused erosion to start, setting the stage for Snowball Earth, which in turn produced the grinding glaciers for some more erosion? Just because it's one gap now doesn't necessarily mean all that rock eroded in one and the same way, does it? Edit: I see SuperStormThunder had exactly the same idea a few hours ago. ;)
