    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.

      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!

  • @Bloodmuffin6
    @Bloodmuffin6 4 роки тому +19

    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.

    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. Still wait to see what science says.

      I saw at least 5 layers that ment it had to be underwater at that time.. place called lawn hill north west qld. Mine called century mine.. dinosaurs found all over the area and we had some stuff found that were made to sign NDA to work in the area.. mainly footprints and whatnot..

      i learned, long ago, that The ozarks were a one of a kind in the world, but never completely understood the why and the consequences. I live just east of the mountains and it is assumed that they cause their own little weather area that extends to the east. I have explored the mountains in Mo and Arkansas, and it is beautiful land. 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.

    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 роки тому +16

      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.

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.

Just because it's one gap now doesn't necessarily mean all that rock eroded in one and the same way, does it?
