    This 70 year old retired geologist appreciates what you are doing with your videos. Always enjoy seeing the science I love promoted. FWIIW, on the age of the science, two points. I remind folks that Lyell and Smith, the founders of geology were contemporaries of our Founding Fathers, so geology has existed almost exactly as long as the United States. But more interesting I think, I received my M.S. in 1975 and in retirement again pursuing more study than economic '"use" of the science's knowledge, I am continually amazed at how much I was taught in the 60s and 70s is now no longer valid. Not a bad thing, but just a sign of geology's relative youth and the advances of technology. Ms. Reizner and Nick Zenter are doing great things for geology today. BRAVO!

    As a geoscientist myself, I couldn't agree more. The problem is that most of the scientific community thinks so little of the branch(es) of science that studies the planet they exist on. So much money and mental energy is wasted chasing geo-political excuses for their agenda, just like the Catholic church did in the medieval times. So extremely little is ever devoted to the geophysical understanding of the dynamics that rules our planet, whether from the surrounding cosmos to the multiple layers of our planet down to the inner core. Things have been occurring most recently (last several hundred years) to our magnetosphere that will definitely affect all life on Earth (especially an electrified world) yet only a tiny fraction of what we need to know has ever been researched. There have been several substantial studies and serious science, that have declared we need to be increasing CO2 levels if to avoid a climate and vegetative disaster that is coming in the natural cycle of Earth's dynamics. The issue really comes into play when multiple conditions arise to intersect each other that leads to very severe and recognizable events in the planet's history. It's NOT just one simple or singular condition that becomes the culprit of catastrophe. Our planet has a tremendous amount of resiliency and so many differing causes and effects counterbalance each other. Until there is a confluence of overwhelming conditions, then the affects can be severe and catastrophic.

    Growing up in CT, NY and VT…. we didn’t really care how it was pronounced…. “In U.S. dialects in the southern regions of the Appalachians, the word is pronounced /ˌæpəˈlætʃɪnz/, with the third syllable sounding like "latch". In northern parts of the mountain range, it is pronounced /ˌæpəˈleɪtʃɪnz/ or /ˌæpəˈleɪʃɪnz/; the third syllable is like "lay", and the fourth "chins" or "shins".[14] There is often great debate between the residents of the regions as to which pronunciation is the more correct one. Elsewhere, a commonly accepted pronunciation for the adjective Appalachian is /ˌæpəˈlætʃiən/, with the last two syllables "-ian" pronounced as in the word "Romanian".[15]”

    Well, Wikipedia ain't the be-all and end-all on everything. However, for the sake of discussion let's look at the preceding paragraph: "The name was not commonly used for the whole mountain range until the late 19th century. A competing and often more popular name was the "Allegheny Mountains", "Alleghenies", and even "Alleghania"." So we northerners came in late to the game... and I bet "al-la-GAY-nee" influenced "a-pa-LAY-cha." We're also the part of the country that turned Pennsylvania Germans (Deutsch) into Pennsylvania "Dutch." Once an altered spelling or pronunciation is used enough, it becomes standard, and in that sense no longer wrong... but I cain't blame the southerners one bit if they don't care for their word being altered/butchered by newcomers, so to speak. So, having grown up using the LAY sound, I now choose to pronounce it LATCH. As for those Elsewhere people tacking that guy Ian on the end... they obviously are wrong. :-)

    I grew up in the Blue Ridge and have lived in the Allegheny. As a kid I loved finding sea shells and fossils in shale outcrops and creaks. And one winter we had two to three feet of snow in the upper mountains. And then one day had temperatures in the 70's. When the floods resided we had several feet of rocks in a small mountain river with some large boulders. And it was easy to sea how mountains that were once as great as the Himalayans have eroded to what we see today.

    The way subduction zones arise at the margin of a continent is not so because the oceanic crust is old dense and sink. It is denser than continental crust and the oceanic crust is literally thrusted under the continent margin by Earth thermal motor that create giant convection cells. The oceanic slab (3.0 g/c3) do not fall into the mantle (3,6 g/c3) because it is less dense than the mantle. It is thrusted forcefully into the mantle by the convection of the underneath mantle.

    I live in Allegheny county Pennsylvania and the hill I live on is topped with Monongahela formation Pittsburgh Coal bed and at the base of the hills is Glenshaw formation Pittsburgh RedBed with Ames limestone lining the valley til I go a mile east the the Casselman tops the hills with Glenshaw halfway down 😮 the geological survey the museum did when I found Batrachichnus foot prints in Duquesne sandstone or the very top of the Grafton sandstone. What was confusing is there’s a red bed and freshwater black shale the splits the Duquesne from other Birmingham shale. However there’s also red bed mixed on top of the Ames Limestone mixed throughout the Grafton sandstone with some fresh water limestone in the Grafton horizon. The museum people did say geography is extremely complex and even within a horizon there will be a ton of different environments within. Keep in mind that you can go a mile from a location to another outcrop of the same horizon but it could be a completely different environment that’s the same age 😮

    Thank you for the presentation. When I originally took a geology course back in 1962, none of this was known. I was taught the major movement was up and down not lateral. As I continues on for my graduate studies in the university of Alaska, I was dealing with professors who could not conceive of the history of Alaska. As I mapped the basalts of central Alaska they looked more and more like oceanic basalts. My professors were in another world, it was now the 1966-8 period when the revolution really started to hit the world of geology. They would not allow me to put into my thesis the reality of what I saw. So my thesis on the basalts of central Alaska had nothing of the reality we now know is true, Alaska is made up of many portions of the island arches that collided with the Rocky Mountains (known as the Brooks Range). How far we have come. The rocks always tell the truth, never ignore what they are telling you! For my Ph.D I did high pressure temperature research for one reason, I could not stand the political environment of the geology profession at that time!

    I came across a KZread video awhile back which explained that the reason the continents fit together like a jigsaw puzzle was not necessarily a total result of pure plate tectonics. As is well known, the circumference of our planet is wider around the Equator than the Polar circumference. So, an obvious question would be why that is the case. If you think of Earth being formed by extreme heat as it spins in its orbit, the spinning itself would cause Earth to expand by its centrifugal force. If you see that before the Earth cooled to its relative state presently, it expanded, it becomes easy to see how the continents were formed. So, you could think of Pangaea as one land mass that existed when the circumference of the planet was much smaller than today. I think it's a fringe theory...but it makes sense.

    Several supercontinents have existed - up to about 8, I believe is what we've uncovered, including Rodinia and Columbia, prior to Pangea. This is something called the Wilson Cycle and has occurred many times. Your fringe "theory" may make sense if only one supercontinent had ever existed, or if we had evidence of the Earth expanding. It's an important scientific lesson to realize that "just because something makes sense, doesn't make it true."

    Plate techtonics depends too much on a paradigm of a homogenous mantle. The newest data plots mantle anomalies that may extend to the core whose content is still a mystery. The idea of an iron core is simplistic so we can model Earth's magnetic field that is observed. Most geology can be replicated in the lab using hypersonic plasma winds that deposit strata in layers in characteristic shapes. No repeated submerging land necessary. No collision fetish which includes techtonics and impact craters. The vast majority of the solar system's craters are plasma discharges between celestial bodies. The Grand Canyon and other water tracts were formed by plasma discharges searching to "ground." The Wilson Cycle doesn't answer the "why?" The Electric Universe explains these cycles by repeating solar discharges that are in rythym with mountain building and extinction event calanders. Our judgement of time is anchored in Newtonian physics that need to be recalibrated to match obersvations and diagnostic tools.

    I find it hard to believe that Antarctica and Australia were once side by side with California ... That's a lot of travel without a lot of explanation ... What was going on in the Mantle to cause such a fantastical journey ? ... And , Why were all the Continents all lumped together ? Were they the remains of the planet that collided with Earth when the Moon was formed ? ... Are all the Continents Alien Material ? ... Or is Earth the result of its impact into a larger Water World ? Therefore we are the lump ... Also it seems the North and South Poles keep shifting , so How do we even know which way is N S E or W at any time in this Continental migration ? ... I can't see how "Scientsts" can possibly explain how all this happened , with so many variables ! ... Therefore , the only thing we know for sure , is the Present ! ... Maybe you should start from the present and work back ... Then you won't confuse people with speculation at the beginning , and fill them with the Facts first !

    She did mention the Wilson cycle. Look into that. If things haven't changed too much since I last learned about all this, very early on during the Hadean period, the earth was more or less molten, and the lighter minerals percolated up and formed the shields, the cores of continents. One way that scientists can determine the location of rocks at the time they formed is that any magnetic materials in the rocks will be oriented toward where the magnetic poles were at the time they formed. The magnetic poles stay reasonably close to the rotational poles, although North and South magnetic poles swap polarity at intervals. It was the mirror image polarities of sediment bands on either side of the Mid-Atlantic ridge that provided the first really conclusive evidence for continental drift. Continents move at about 2-5mm per year, about the speed your fingernails grow. This doesn't seem like a lot, but when you have hundreds of millions of years, it works.

    @@b.a.erlebacher1139 That's my Point ... These Know-it-all Scientists are making Statements of Conclusion through weak and Spotty Evidence ... We have an early Earth that's molten , Moon making collisions , a Water World , and a super continent lump with its bits mixed around like a Jigsaw puzzle ... all bumping into each other ... Then after a few mixing of the pieces ... Mother Nature finally spreads the Continents around the Globe , with some bits barely moving and some speeding halfway around the world ... Then on top of that you have pole shifts and flips to add to the Confusion ... LOL ! ... and if continents are moving at 5mm/year ... 1km would take (5mm/10mm x 100 = 1000mm/m x 1000m/km = 1km = 1,000,000mm/5mm = 200,000 Years to move 1km ... the Atlantic is 5000km wide ... So 200,000 x 5,000 = 1,000,000,000 = 1 Billion years ...... But the Dinosaurs lived 300,000 years ago ... when the Atlantic was 2/3ds spread ... So how do Similar dinos live on Spread Continents ?? ... Alexa says the Appalachians are 500 million years ago ... LOL ! ... So they must have formed when the Atlantic was Half Spread ?

    Hi! You can use the very same technology you are using right now to find out what is going on - we actually do have very good explanations based on ample evidence gathered over more than a century. I did not post my Plate Tectonics lecture because there are already so many great ones, but maybe I will. I recommend this: kzread.info/dash/bejne/fXZrqtx_YrKZe8o.html
