The cost of living crisis appears to be a global problem, although here in the UK it has been made worse by the increase in the prices of many goods.

It is extremely, extremely rare to find meteorites in nature, unless you scour ice ablation zones in Antarctica, particularly on areas of blue ice, or certain deserts, such as the Sahara or Arabian deserts, where tektites can accumulate over time, because they are extremely dry, which helps preserve their reactive chemistry, and no precipitation or sediment can cover them. Most meteorites found these days are found on such expeditions to Antarctica.

It has been shown that "slab pull" is even more powerful than "ridge push". These are the two main forces in seafloor creation. Is "slab pull" what you mean when you say "drag"? I agree, the earth is such a dynamic planet. I never tire of trying to learn more about it.

What is most amazing is that humans can gain this level of knowledge by sheer observation and tested conjectures. By sharing intellect. This despite a propensity for know nothing politics!

[@lotharschiese8559]

@@harrietharlow9929 Very few are speaking to the fact earth has a molten mantel complete with convection currents, the convection currents must be recognized as the driving force behind wrenching the continents, the plates apart and causing subduction. Like watching a huge chunk of a cinder cone that broke off, and watch it be carried away on top of flowing lava. Think of a big observatory telescope, some 400 ton, floating on liquid mercury, the crust and the liquid mantle gives the same result and if if the mantle is on the move because of convection, the crust is going to move along with it. When 2 pieces of crust come together, one that is more flexible will bend and follow the path of least resistance, downwards, under the more massive continent.

[@harrietharlow9929]

@@lotharschiese8559 Well, yes, agreed. That is, of course, the man driver of plate tectonics. This was intuited by Arthur Holmes as far back as 1940. In his " "Principles of Physical Geology", he posits mantle convection as the mechanism of continental drift. But if I am understanding subduction correctly, the operative mechanisms are "ridge push" and "slab pull" and of the two, "slab pull" is the stronger and more influential.

They'll be nothing but dust in how many years? How should I know? I know they can't be here in 500k years but let's ignore common sense and say 5million years (which is ridiculous). I know what a fossil is but the fossilized bones of an animal is Not capable of being anything but dust after hundreds of millions of years.

Who do the Cartels Profit more from having in power in DC? A. Dems who refuse to secure the border. OR B. Trump n his Wall. Ok, nobody says cartels profit more from Trump. They don't.

[@haraldurkarlsson1147]

I addition to what I stated before I find it odd that no mention is made of drag along the base of the plates as a significant force. Clearly subduction (with its plate pull) plays a major role but some plates that a few subduction zones (North American Plate comes o mind) must be moved mostly by the drag. The mid-ocean (and rift systems like in Iceland) are clear indications that the push plays a minor part in the movement (as indicated by the tension seen in the volcanic rift zones) and that leaves drag as the major force.

[@harrietharlow9929]

The whole phenomenon of drag (slab pull?) is fascinating, at least to me. Another thing found out is that the Juan De Fuca plate is subducting at an extremely shallow angle. I understand that its predecessor, the Farallon, subducted at a similarly shallow angle which influenced the building of the Rocky Mountains. That surely has affected and still affects the North American Plate as well as the Juan De Fuca plates, yes? I'm just an amateur who wants to know more about the geological processes of our planet.

[@tiffanym4202]

Makes me wonder why thin oceanic crust subducts under continents and yet that massive, heavy continents just keep floating. I then wonder how that thin oceanic crust manages to cause uplift on the continents under which it is subducting. Something is still missing from the equation. Lastly, it has been said that the continents drift at a somewhat stable speed. I'd like to know if it were possible for them to speed up, such as 2 inches a year instead of an inch. Oh, I have one more: when plates are sliding by one another and get stuck, how do they manage to force their way past instead of bumping back the way they came? I love programs like this but am always left with more questions.

[@billwalsh388]

I think that the spin of the earth makes the Earth's crust shift.

[@Nobody-cw4wm]

I seek an answer to a question I’ve had for ages. With all the extra water going into our oceans from polar ice melt etc, will the extra weight create more earthquakes & movement of tectonic plates by compression?

[@boxsterman77]

There's no extra weight. There's redistribution of some weight. But your intuition is somewhat right. The North American formerly under miles of glaciers is still rebounding from the release of that pressure. To the best of my knowledge, this is a gradual uplifting move that doesn't involve must seismic activity and doesn't involve the lateral movements of plates whatsoever.

8/8/2022 This is a very interesting video, I have no formal training in Geology, beyond high school science classes, but have been fascinated by the dynamics and mechanics of our planet, all my life. We can only understand, clearly, what happens on the surface and to the depth we can actually penetrate, so some of what is said here, like with all natural sciences, is conjecture and supposition, even if it is a well educated idea. The recent occurrences in Iceland clearly support the "pulling apart" actions in the Atlantic, and the volcanic activity in the Pacific, clearly support "subduction". Even so, the geological activity of our planet is the underlying force driving our "ON THE SURFACE" environment. No mater how old or young YOU might believe this planet might be, it is changing continuously, effecting the weather and ecology. This planet, in 2022, is experiencing a major adjustment and no NEW GREEN DEAL is going to make any difference. When we learn that earth is a living, breathing thing, then we might learn that it controls us not the other way around. Everything we see today took millions of years to form, now change is happening again. What Earth's future holds does not lie in our ecological efforts, but in the geological change. The changes happen slowly, but when the occurrences happen, they happen very quickly, and you can not stop the process. ;-)

Nothing new, between 45 to 55 volcanic eruptions a year on average now. Remember before 100 years ago we didn't even know how many volcanoes there were. There are earthquake frequency maps that were developed so you can see zones where eq's up to 5 are common. Some KZbinrs make a living predicting these small quakes, but they rarely ever predict a big quake, it is hardly predicting when you're using statistics. Big quakes are just too random to predict with any regularity. Here's an old video detailing it. kzbin.info/www/bejne/eHvSend5acRjd7c Earth doesn't grow volcanoes extremely high not only by moving crust, but also has higher gravity putting a limit on how high mountains can grow. What most people don't know is that the crust contains so much oxygen if released it would kill off most life. Silicates are SiO2, FeO2 and TiO2 Silicon, titanium and iron alone hold enough O2 to more than double the 22% we live on. Much is made about the magnetic poles are reversing, but there isn't any mass extinction events found around Pole reversals. Also magnetic strength waning and waxing is just natural.

34:00 this isn’t quite true. The paleopositions of the continents during Cryogenian Snowball Earth events are poorly constrained.

Its paleolatitude at that time was directly on the equator, and was subject to immense chemical weathering, and its vast exposures of mafic and ultramafic rocks soaked lots of carbon dioxide from the atmosphere through precipitation/acid rain. Combined with the effects of aerosols erupted by the LIP, this was thought to have created the initial conditions for Snowball Earth, which may have been exacerbated by the position of the Rodinia supercontinent away from the poles, and set the stage for a feedback process involving runaway low albedo, whereby the earth’s reflective value became less and less, causing colder and colder temperatures and more and more snow, which again caused lower albedo values, and so on…

Explanations are assumptions. Were you there ? Who told you the How let alone the Why ? It is amazing in every way. creation has a Creator !

Volcanic activity is nothing more than 'core incontinence'!

Why was fossil-fueled climate warming so trivialized in this video? Just because it doesn't rival the Siberian Traps doesn't mean it's not lethal, or within our ability to control. The Pleistocene Ice Age and its Glacial Maximums weren't as dramatic as Snowball Earth, but they changed life for the entire planet, and not in ways we would want to glibly welcome back. That advisory may be more urgent in regard to anthropogenic global warming. Let Earth be Earth, but humanity should express the sentient volition with which we were gifted. Strangely, you wouldn't learn how or why by watching this myopic geopic.

um the only planet that has oceans plate techtonics ? wasn't a very good intro to this

Great info but no closed caption??

I've always wondered what would happen if that tiny thread of land that connects Central and South America together were not there, as in ancient times. The oceans would flow through there. The currents would have to change. I think something like that would impact the entire world. Certainly sea life. And shipping. And shorelines. It would be cool if we could get a computer prediction model of the changes that we could foresee. Not that it matters because that's not gonna happen. But just out of curiosity that would be cool.
