Part 1 Hello London, I have enjoyed this video on plate tectonics. I know it has been several years since it was first posted but I found it far too important to not stop and comment on this subject. And more specifically, to allow me an opportunity to express an opinion as to the true and accurate description of the mechanism involved. It’s interesting when you consider how much the standard model is dependent on the mantle as having a convection regime. The great Arthur Holmes is credited to its acceptance in geology and the suggestion it could be the missing energy source to drive the tectonic plates. But, he also readily admitted it could be wrong. To date there is no direct observable evidence of the mantle having an up welling of lower density material resembling a convective cell or even a conveyor belt type of mantle movement beneath the tectonic plates. The standard model is only speculative in these regards. But even more importantly, the surface observations over the years have continually presented evidence of a mechanism of plate movement far different than what convection could provide. The mantle appears instead to be a solid state material that is 2,900 km thick, with pressures so great that at only 100 to 250 kilometers carbon can be squeezed into a diamond matrix. There are now a growing number of researchers who are skeptical of the standard model’s over-dependence on such an overly simplistic idea. Prof. Don L. Anderson of the Caltech seismological lab., had with many other geologists made critical assessment of the standard model. authors.library.caltech.edu/25038/122/Chapter%201.%20Origin%20and%20early%20history.pdf New Theory of the Earth Anderson, Don L.

"Because of the combined effects of temperature and pressure on physical properties, shallow stratification may be reversible - leading to plate tectonics - while deep dense layers may be trapped at depth." "Conventional (Rayleigh- Benard) convection theory may have little to do with plate tectonics. Convection is so poorly defined that it is difficult to consider it even a viable working hypothesis unless there is some direct observable evidence that it can make anything resembling a prediction of observation." Carlo Doglioni, the geophysicist and former president of the Italian Geological Society, and since April 2016, the president of the National Institute of Geophysics and Volcanology has published some very remarkable papers in regard to mantle dynamics and plate tectonics. www.dst.uniro...antle_Dynamics_ MANTLE DYNAMICS AND PLATE KINEMATICS Carlo Doglioni, La Sapienza University, Rome, Italy Roberto Sabadini, University of Milan, Italy ". . . . . none of the proposed models of mantle convection can account for the simpler pattern in plate motion we observe at the surface, nor has a unique solution been proposed for how material in the mantle convects. At the moment there is no way to link mantle dynamics and plate kinematics at the surface, considering that the mantle and lithosphere are detached. The Atlantic and Indian ridges are in fact moving apart with respect to Africa, proving not to be fixed both relative to each other and relative to any fixed point in the mantle. This evidence confirms that ocean ridges are decoupled from the underlying mantle." This remarkable observation above expresses the reality of the situation. Geologists need convection to be a viable solution to plate movement, but after 90 years, its existence, let alone its functionality, remains unanswered in the standard model. www.electroplatetectonics.com/
4:50. Incorrect. The oldest continental crust isn’t 4.3Ga. You’re referring to the Jack Hills. Those zircons are detrital. That means they were transported from somewhere else and incorporated into the conglomerate that houses them. The conglomerate was deposited much later

Great descriptions, but the music was very distracting.
thank you so much for this! the music kinda distracts me but still very full of information.
That was super helpful!! You explained it so much better than my science teacher did! Thank you!
oh my god!! this is amazing. it literally saved me during my exam.
Wow thank you so much! Even if I'm not a native english speaker I understood everything even better than in class :)
Thanks for making this video! Everything is very clear 😊
Thanks! I couldn't make heads or tails of my textbook at first so this was really helpful c:
saaaaame here.
the book was terrible at explaining this

okay boomer
Ok pseudointellectual
@@esconis5304 I’m a licensed professional geologist who literally studies detrital zircons what’s your qualifications?
Great t shirt Really represents what we’re all about good on ya
Kinda representing American pride and dominion over the moon (in a good way) methinks...
Thank you so much! This video is really helpful
Thank you I understand It very well.
gusto mo nabang maging hatdog?
@@charisjanejayma1532jumbo hatdog kaya natin to
mag tender juicy kana!!
Lavan
Weeee
Very clear explanation
can you turn the music up i cant hear it
Very informative, thank you!
Glad it was helpful!
What are the resisting forces?
I mean I don’t think I’ll ever learn it because just liek in class and in here I got distracted and started reading comments
hello jenks , as we know before continental formation sea was there .
So, how can be oceanic crust will be younger then continental crust?
This is too helpful! I found hope now.
Thank you so much this helped me from my report
I just spent the whole video dancing
so helpful thank you so much
Nice background beat
is there one on resisting forces??
thanks man! really helpful -
Tip: play it at x1.5
it really helped me i was really struggling with this....
thank for sharing!
much better than my teacher
if you could turn of the background music thank you
Thank you
whats the music?

thank you!!!
Do you know what is plate boundary???
Lmao
love your shirt
hailey Y yeah I agree totally
thanks!!!!!..... really appreciate
great!!!
nice hair bro
thanks...i didnt understand my textbook.....

I HATE SCHOOL
I don’t hate school I hate the lessons lol
The bgm is so disturbing
Music is way too loud! Still like the vid tho
excellent explanation, poor choice of music
Look at this dude
yapuh nya kyaruh naku
fucking hell the music is so distracting
hi p lesa, and2 aq gais helo
bro so goofy
Geography is really a dead subject but you tried your best to bring it alive (Tums up) for that.
He’s so cringy no offense
