What do you think about the Karin Sigloch-Mitch Mihalynek conclusion that tectonism is propelled by "90% slab-pull (subduction) and 10% ridge-push (spreading ridge)"? This limits all tectonic observations to the crust and ignores the role of the mantle. My observation of the tectonic principle is a conveyor belt or tank track (slab) + back drive-wheel (mantle convective upwelling) + conveyance/motion ( slab on mantle convection flow) + front idle-wheel (mantle cooling descent.) I understand their conclusions, but only to the point of accommodating the rigid crust for conveyance via mantle convection.
If you haven't heard of Nick Zentner at central Washington University he's a geology Professor who has a free on line teaching program that he started doing more actively when covid shut things down he started doing in his back yard cause he was bored.He got a huge following and stimulated us already interested in the subject to learn more. He didn't quit and neither did we so you may notice plenty of us listening to you and other geologists also. So you might like also looking up Nick. Really nice man also and great teacher ( he takes us along on hikes and field trips by carrying his phone). Thanks for sharing your very interesting talk. Just a side note ( a close friend's mom was Australian.. I'm old so she has passed... and my parents liked to take British tours and became good friends with a couple from the tours who were Australian and they came to USA and stayed with us and we toured them around... so I'm quite fond of Australia ). Please do share future talks on utube also.
Dear Michael Tellinger, You are an inspiration to us all! We've briefly talked in some of your previous video's livechats about scheduling you for a podcast interview. sadly the email address you had posted at the time didn't work for some reason. What is the best way to get a hold of you to schedule a future interview good Sir? I promise that you will not be disappointed! i have many parallel research discoveries to share with you, as well as help verify your own discoveries! especially when it comes to megalithic sites and giants! I have found many such sites around where I live here in Alberta Canada
Why is it that if you bury the ocean floor by reverse age you get all the continents fitting together into a ball on a smaller globe? That seems like an astounding coincidence.
There was ocean floor during the formation of past supercontinents as well. The ocean floor and even some continental crust gets recycled into the mantle via subduction. Unfortunately we don't know what it looked like, other than an assumption that it looked much like it does today.
Remember new ocean floor keeps forming constantly along the mid Atlantic ridge and that pushes Europe and Africa eastward and North America and South America westward ( then subduction probably occurres on both sides of the Pacific ocean ). Basically the land masses are always on the move and occasionally probably come together into gondwana like masses with the continents all together.
@@DonnaCsuti-ji2dd There are mid-Pacific ridges as well producing new ocean floor, pushing Asia West, and North America East. But how can that be? It only makes sense if you realize that the earth is expanding. The so-called "subduction" is assumed, not proven.
@@LymanAlphaBlob All of the ocean floor around the globe is no older than 200 million years. How is it that there is not one spec of ocean floor that can be aged prior to the "breakup of pangea"?
@@peterdebaets4590 there is plenty of ocean floor around the globe older than 200 million years. You don't even need to look in the water. A large percentage of the fossils/fossil sites we have access to today on dry land are from ancient lithified seafloor that is currently above sea level. Do you believe that there are fossils older than that?
Not even a passing mention of the atrocities committed by imperialism and the diamond industry against indigenous peoples and the planet, rendering that land acknowledgement completely meaningless.
I've always wondered who the motivated individual is that uploads high-fidelity 3D scans onto Sketchfab! Similar to Dr. Roach's work up north, I believe Monash scans cultural sites for GlaWAC in Victoria. We really should be doing the same for at least the two known hand stencils here in Tasmania. Although these scans are intended for educational purposes, they actually serve as fantastic 3D assets for artists creating virtual landscapes. Tasmania boasts some of the most visually striking geology.
Thanks for shering this nice presentation AUDIO is terible- but... if you switch ON SUBTITLE ... problem solved !!! At 40:30 you presented nice map that portrays Antarctica together with Australia. High mountains from Antarctica were creating enormous GLACIERS presented as a white stretches on that map. One of them goes directly from Antarctica to Adelaide ... ... where it created beautiful Glacial features . Thay are exposed in Hallett Cove Conservation Park with Glacial Hike, Hallett Cove ... Just google images: * sugar loaf Halet Cove * black cliff Halet Cove *
I know a spot where the joining may have occurred. I've found sea fossils in sandstone and mudstone well above sea level out in Magra in the Derwent Valley.
These beautiful birds get shredded to pieces by those annoying noisy minors it's a shame killing all the native birds they mate like rabbits and attack my cat on ground from trees the lot...ABC done a doco on them few months ago but nothing will change so it's a never ending battle until someone shoots them to protect our.native special birds....noisy minors shouldn't be on the native list they attack everything from a cat to a curriwong and kookaburras rosellas only thing they don't attack is a magpie or a black cockatoo....wish someone would slug them there annoying I hate noisy minor birds there territorial and they are bloody ugly and sound like car alarms I hate them
Thank you very much Anita and Marley. I enjoyed your presentation, learning of your 3 years of investigative work, gaining some insight into the history and viewing some of the art of that era👋😊Cheers, Lindsay Hope
The Earth is cooler with the atmos/GHGs/albedo not warmer. To perform as advertised the GHGs require “extra” energy upwelling from the surface radiating as a black body. The kinetic heat transfer processes of the contiguous atmos molecules render that scenario impossible. No greenhouse effect, no GHG warming, no man/CO2 driven climate change or Gorebal warming.
Thank you for having me! It was such a pleasure chatting to society members about this. Next time, I'll be sure not to plan to present the day after a big wedding 😂
