Assembly of the Appalachians

[@0.01_bacteria]

My exam is in 2 days and this is very useful to understand visually . adding audio description will make it even better for the students.

[@TheAnarchitek]

The Appalachians are essentially synclines, strata turned sideways to the surface, evidence of a very ancient collision that happened when that part of ONAC was somewhere else, long, long ago. It's a part of the same "mountain" range that runs diagonally across Scotland, and a little bit of western Ireland, along with the Atlas Mountains, in Morocco, all the same original crust but separated by thousands of miles, today.

[@geologvlog881]

Absolutely!

White print on light gray background is hard to read. Could use a little audio description.

[@0.01_bacteria]

agreed

[@maryroller4417]

Going to have to look at this one frame at a time. Very interesting.

[@charliewatts6895]

Beautiful, and subscribed.

Who knew Cleveland was in the Appalachian Mountains? I guess that's why it's such a popular ski resort.

[@carriehunt9741]

So good to see some geology of the Blue Ridge in there. My mountains! How I miss them. Thank you!

[@MrToddino]

An explanation of all of the geological jargon used here would have been very appreciated. Rattling off names of eras and formation types without giving context doesnt help much

[@donchesnut4075]

This channel states that it is for geologists. Geologists understand these terms. This is not the channel for you.

[@MrToddino]

@@donchesnut4075 well shit

[@Wedge53]

Geology is a deep dive.

There is an excellent lecture series on geology here on KZbin by Paul Day - 25 lectures. Geology 101

Too fast to read and comprehend everything. Yes, I know I could pause, but this clip was not very user friendly. 😊

[@Hullj]

Yes. Yes. Yes. The value of the information is questionable as a result.

[@metfraser303]

Turn it to 0.5x speed (tap the gear for this) and maybe turn down the sound. This brought it to perfect reading speed for me.

[@mikelouis9389]

You definitely deserve more subscribers! Here's one more.

[@johnaugsburger6192]

Thanks

I have difficulties understanding the video. Perhaps an animation would have helped.

So the Grenville Block is an exotic terrane along the East Coast of North America?

[@Wedge53]

Looks to me that the Grenville Orogeny appeared once the supercontinent of Rodinia was formed (appx 750 mya?). I am just a casual observer, so I have no expertise.

[@twotone3471]

North America has but a single Craton, generally in Eastern Canada "The Canadian Shield" as its sometimes called. All the rest of North America is Exotic Terranes, though the rocks at the surface may be far younger than when the collision happened.

[@charliewatts6895]

@@twotone3471 The unchanging craton. Nothing really happens outside of its margins.

[@twotone3471]

@@charliewatts6895 I think you mean inside of its margains, but I know what you mean. North America's ancient self was called Laurentia, and was made of the core of the Canadian shield, another block consisting of Greenland, and Wyoming's Micro-Continent (goes beyond the political state) which are very, very old. The rest of the Continent was added on a piece at a time, or rarely the result of a failed rift valley or outright volcanism. But for the old core of North America, not a lot happens, minus the odd asteroid impact, or a glacier or two.

[@darkoil1973]

very well put, thanks.

[@StsFiveOneLima]

Maybe a little commentary.....?

[@phsal5182]

thank you!

[@williammizebee]

This is interesting but how much is this a hypothesis theory? Cleveland is distant or the edge of these formation Pennsylvania and West Virginia no geology is not easy to understand to us non geology peoples

[@sejal9765]

Thank you

[@mbvoelker8448]

Cool and informative, but moves too fast to read.

[@nancytestani1470]

This is so fascinating?

[@FAHHH-Q]

All this movement at the rate our finger nails grow is what kills me .
